Summer Fungi (And friends)

Finally, after I believe two years since my last full mushroom post, I’m able to do another. I thought I’d start with these pretty little butter wax caps (Hygrocybe ceracea.) I’m not a mycologist and I don’t even like eating mushrooms but I sure do like looking at them because they can be very beautiful.

I think theses small white mushrooms might have been flat oysterlings (Crepidotus applanatus.) They are a pure white wood rotting mushroom that feel like your earlobe and I’ve read that they’re sometimes called simply flat creps. They should not be confused with oyster mushrooms because they are inedible.

Here is the what the underside of the previous mushrooms looks like. I’ve heard that the gills brown with age so these examples must have been quite fresh.

I was able to see something I’ve never seen before; the “birth” of a Berkley’s polypore (Bondarzewia berkeleyi,) the largest mushroom I’ve ever seen. What you see here are at least three mushrooms erupting from that lumpy, whitish mass.

There were two groups here near a tree and this is one of the groups when it was young and just taking on that familiar shape. This mushroom grows at the base of hardwoods in the east and in the west a similar example, Bondarzewia montana, grows at the base of conifers.

These photos were taken over a period of about three weeks, so this is a slow growing mushroom. As I said, they can be huge, and this one was probably at least two feet across. I don’t know if it had finished growing but as this photo shows something had been eating it. I’d guess a squirrel. They get to a lot of mushrooms before I do.

From the gigantic to the almost microscopic. These eyelash fungi (Scutellinia scutellata) grow on the wet, seeping wound of a standing tree. Each of the bigger ones is less than the diameter of a pea. They are considered cup fungi and they get their name from the hairs around the perimeter. The hairs can move and sometimes curl in towards the center of the disc shaped body. I’ve read that some believe that the hairs might collect moisture, similar to the way spines on cacti work, but I’ve always found them growing in very wet places so I’m not sure about that. The shine you see in the photo is caused by the camera’s LED light. It’s quite dark where these grow.

Fan shaped jelly fungi (Dacryopinax spathularia) are spatulate fungi, meaning they’re shaped like a spatula. These grew out of the crack in a log and were quite pretty, I thought. Sometime you’ll see spatulate fungi that are more fan shaped or club shaped but these examples seemed to live up to the name fairly well. In China it is sometimes included in a vegetarian dish called Buddha’s delight.

According to Mushroom Expert.com Staghorn fungi (Calocera cornea) grow after heavy rains on the barkless, dead wood of oaks and other hardwoods. This log had its bark still on but these small fungi came out from under it.

The website goes on to say that this jelly fungus appears as clusters of slick, cylindric fruiting bodies with rounded-off or somewhat sharpened tips. In fact it looks more like a tiny club fungus than a jelly fungus. These examples covered a good part of this log. They’re fun to look at but getting a useable photo can often be a little less than fun. These fungi are quite small.

You can tell that it has been rainy, hot and humid when slime molds start to appear. Despite the name slime molds aren’t molds and they aren’t always slimy. Unfortunately, though everybody argues about what they aren’t, nobody seems to know exactly what they are. The easiest way for me to think of them is as a single celled organism like an amoeba, with thousands of nuclei. Many headed slime mold (Physarum polycephalum) likes decaying organic matter like leaves and logs because this is where it finds its food supply of bacteria, yeasts, mushroom spores and microbes. The slime mold in the photo is in a vegetative phase called plasmodium, which is when it can move by ”streaming ” at about 1 millimeter per hour. The plasmodium is made up of networks of protoplasmic veins and many nuclei which move to seek out food. Once it finds something it likes it surrounds it and secretes enzymes to digest it.

Here is a closer look at a “streaming” many headed slime mold on an oak leaf. It was moving, but so slowly the eye can’t detect it.

This example of a many headed slime mold looked like it was climbing this stone. There must have been something on the stone very appealing to it to have it do this. I think this was only the second time I’ve seen a slime mold on stone.

Slime molds can be very beautiful things and one of my favorites is white finger slime (Ceratiomyxa fruticulosa var. fruticulosa.) Finger is a good description of the way this slime mold appears. It’s hard to relate just how small these are, but in each ‘finger” would be less than the diameter of a toothpick, and in length possibly 1/16th of an inch. As if that didn’t make photographing them tough enough sunlight is an enemy of slime molds, so they are only found in very dark places like the undersides of logs.

I was pleased with this photo because it shows something I’ve wondered about for years. I once saw a log with hundreds of clear, antler shaped beings on it and I’ve wondered what they were ever since. Now I know that they were young finger slime molds, because you can see two of them just right of center in this shot. They’re so small I couldn’t see them when I was taking this photo.

The honeycomb coral slime mold (Ceratiomyxa  fruticulosa  var. porioides) in the above photo that I took previously is a close relative of the finger slime mold we just saw. When conditions are right and food is running low this organism will produce the white honeycomb shapes seen in the photo. They do this prior to fruiting, which is when they create the spores needed to reproduce. Without magnification this slime mold looks like a white smudge on a log and is far too small for me to see in any great detail. I’m always surprised when I finally see what is in the photos.

Each one of the yellow dots you see in this photo is part of a slime mold called Physarum viride. As far as I can tell it has no common name. This slime mold likes decaying logs and can be found in conifer or hardwood forests. Each bright yellow “Lens-shaped structure” is on a stalk, and as they age they will blacken and harden, and start to crack open before releasing their spores to the wind. Each of these tiny “dots” would measure less than the diameter of a common pin.

The white cousin of the slime mold we just saw is called Physarum alba. These structures are also stalked and except for their color behave in the same way as their cousins. You have to look closely but you can see how some of these have cracked open to show their black spores inside.

As I’ve said here before Indian pipes (Monotropa uniflora) are not fungi but because they like the same conditions they often show up when the fungi do, and so they often end up in these mushroom posts. I’ve included this one because I don’t think most people ever see them doing what this one is doing. When an Indian pipe is ready to become pollinated and begin producing its dust like seeds it turns is flower straight up to the sky and slowly browns and hardens, finally looking a lot like it’s made of wood before splitting open to release its seeds. They usually crack open in very late fall or winter.

And here is a view looking down into an Indian pipe flower; a view I’m guessing many have never seen. It is thought that the flower turns up like this so its ten yellow pollen bearing stamens surrounding a large central style will be more visible to pollinators. It is fitting that the plant appears in a post on fungi because it has recently been discovered, according to the University of Texas, that Indian pipes are associated with a fungus which obtains nutrients directly from the roots of green plants. That makes Indian pipe a parasite, with the fungus acting as a “bridge” between it and its host.

Chanterelle mushrooms (Cantharellus cibarius) are often deformed when we’ve had a lot of rain and over 12 inches of rain in a little more than two weeks is a lot, but this chanterelle looked fine. Chanterelle mushrooms are considered a delicacy but I’ve had mushroom experts tell me that you can never be 100% sure of a mushroom’s identity without examining its spores under a microscope. Since I don’t own a microscope that means you can never be sure of my identifications either, so please don’t eat any mushroom you see here until you have an expert examine them. There are mushrooms so toxic that one or two bites have killed. We have mushroom walks led by an expert or experts here. If you want to become serious about mushroom foraging you might find out if you have anything like them in your area. They’re a good place to start.

From the side chanterelles look like trumpets, but so do many other mushrooms including the false chanterelle, which is inedible. False chanterelles have orange flesh, while true chanterelles have white flesh. This example had white flesh but I still wouldn’t eat it without showing it to an expert first.

Common stinkhorns (Phallus impudicus) have an odor like rotting meat when they pass on, and that’s where their common name comes from. Though this example was dry, the green conical cap is sometimes slimy and shiny. It uses its carrion like odor to attract insects, which are said to disperse its sticky spores. Its stalk is hollow and spongy. I find these mushrooms almost always growing on some type of wood, often wood chips or very rotten logs. Though this one looks like it was coming up in a lawn I’d bet my lawnmower that there was wood in some form under the grass.

Jackson’s amanita (Amanita jacksonii) is also called American Caesar’s mushroom. It has a bright orange or orange-red cap with a lined perimeter, yellow gills, and a white, sack like volva. The volva is what remains of the outer skin, called a universal veil, that enclosed the mushroom in its young “egg” stage. As the mushroom grows the universal veil tears open to finally reveal what we see here. I had to brush a few pine needles away so we could see it clearly.

The Jackson’s amanita in the previous photo turned into this in a single night. It must have been 3 inches across, and it was a very colorful, beautiful thing.

I hope you enjoyed seeing these beautiful wonders of nature and I also hope you will be able to find plenty of mushrooms in your area this summer. You don’t have to eat them or even know their names; just admire their beauty. They’re popping up everywhere here.

The sudden appearance of mushrooms after a summer rain is one of the more impressive spectacles of the plant world. ~John Tyler Bonner

A Walk Around the Neighborhood

I decided to take a walk through my neighborhood recently. I do this now and then when I don’t feel like driving anywhere, but also because it’s a good way to learn about everything that grows in my area. As I’ve said before if someone knocked on my door and asked where to find any one of a hundred different plants, there’s a good chance that I could lead them right to it. That’s when you know that you know a place well. The old road in the above photo cuts through a mixed hard and softwood forest of the kind that is so common here. It makes a pleasant place to walk and look.

There is a small pond nearby which over the years has gotten smaller and smaller due to the rampant growth of American burr reed (Sparganium americanum.) The plant has now cut the pond in half and I expect the far half to be completely filled in a few more years.  I’ve seen many ducks, geese, and great blue heron here in the past but they don’t seem to come very often anymore. I’ve also seen this small pond grow to 3 or 4 times its size after a heavy rain, so full that it overran its banks. That can get a little scary, because that means the one road in and out of the neighborhood can be under water.

There is a small grove of gray birch (Betula populifolia) near the pond and I often search their branches to see if any new lichens have moved in. Gray birch doesn’t have the same bright white bark that paper birches do, but lichens seem to love growing on their limbs.

Black eyed Susans (Rudbeckia hirta) bloomed near the pond. This is one of our longest blooming wildflowers. It usually blooms from June right up until a hard October frost.

Flat topped white aster (Doellingeria umbellata) also bloomed near the pond. This aster can get 5 feet tall and has smallish white flowers. Its common name comes from the large, flat flower heads. Butterflies and other pollinators love it and I often wander down to where it blooms to see if there are any butterflies on it. It likes moist, sandy soil and plenty of sun, and it often droops under its own weight as it did here.

Hedge bindweed (Calystegia sepium) winds itself among the tall stems of the flat topped white asters. It is said that bindweed purifies and cleanses the body and calms the mind. Native Americans used the plant medicinally for several ailments, including as an antidote to spider bites.

The small pond that I showed a photo of previously eventually empties into a large swamp, which is called a wetland these days. I’m guessing that beavers and muskrats keep the water way open through it; it has been this way for as long as I’ve lived in the area.

I’ve seen two odd things on staghorn sumac (Rhus typhina) this year that I’ve never seen before. First, when the berries were ripening they went from green to pinkish purple to red instead of from green to red, and now they are a dark purple, which from a distance looks black. I wonder what is going on with these plants. I’ve never seen this before.

A bumblebee worked hard on Joe Pye weed blossoms. Soon the cooler nights will mean that bumblebees will be found sleeping in flowers in the morning.

Native rough hawkweed (Hieracium scabrum) is one of the last of our many hawkweeds to bloom. An unbranched single stem rises about knee high before ending in a terminal cluster of small yellow flowers. The plant blooms in full sun in late summer into early fall for about 3-4 weeks. Many species of hawkweed, both native and introduced, grow in the United States and I’d guess that we must have at least a dozen here in New Hampshire. Some of our native hawkweeds bleed a bitter white latex sap and Native Americans used to use it for chewing gum. I’m guessing that they had a way to remove the bitterness and probably found ways to flavor it too.

There is a lot of sand in this area and it is one of only two places that I know of where sand jointweed (Polygonum articulatum) grows. I didn’t see any of the tiny white flowers on this walk but I did see the plants. They should be blooming any time now and will appear in a future flower post.

I’ve found that it is close to impossible to get a photo of a forest while you’re in it. I’ve tried many times but it never seems to work. There’s just too much going on.

So since I can’t get a good photo of the forest itself instead I take photos of the things that live there, like this purple cort mushroom (Cortinarius iodeoides.) Purple corts are having an extended fruiting time which is now in its fourth week, I think. I’ve never seen so many and I’ve never seen them fruiting over such a long period of time.

Something else that’s is strange in the fungi kingdom this year is how jelly fungi like this witch’s butter (Tremella mesenterica) has fruited all summer long. I usually only see it in early spring, late fall and winter when it is colder. It could be because of all the rain I suppose; jelly fungi are almost all water. I almost always find them on stumps and logs; often on oak. After a rain is always the best time to look for them because they’re at their best when well hydrated.

We’ve had at least a day of rain each week all summer but it’s been on the dry side over the past couple weeks, so I was surprised to see this white finger slime mold (Ceratiomyxa fruticulosa, variety fruticulosa) growing on a log. The log was very rotten and held water like a sponge, so maybe that’s why.

There is a small glade of lady ferns (Athyrium filix-femina) out here and I like to stop and admire the lacy patterns they produce and how they wave in the breeze like they were on this day.

Bracken ferns (Pteridium aquilinum) are starting to show some fall color. Bracken is one of the oldest ferns; fossils date it to over 55 million years old. The plant releases chemicals which inhibit the growth of other plants and that is why large colonies of nothing but bracken fern are found. Some Native American tribes cooked and peeled the roots of bracken fern to use as food but modern science has found that all parts of the plant contain carcinogens.

Wild sarsaparilla (Aralia nudicaulis) is also starting to turn. These plants sometimes turn a deep purplish maroon in fall but more often than not they go to yellow. Native Americans used the root of this plant as emergency food and it was also once used to make root beer.

Giant foxtail grass (Setaria faberi) grew in a sunny spot at the edge of the forest. This is a big annual grass that can form large colonies. Its nodding, bristly, spike like flower heads (panicles) and wide leaves make it easy to identify. The flower heads go from light green to straw colored as they age.

This walk ends in a meadow full of little bluestem grass (Schizachyrium scoparium,) which is one of my favorite grasses. I hoped to show you its flowers but it was a little early for it to be blooming. Little bluestem is a pretty native grass that is grown in gardens throughout the country. It’s very easy to grow and is drought resistant. Purplish-bronze flowers appear usually in August but they’re a little late this year here.

This was one of those perfect New England days in late summer where the spirit of autumn takes a first stealing flight, like a spy, through the ripening country-side, and, with feigned sympathy for those who droop with August heat, puts her cool cloak of bracing air about leaf and flower and human shoulders. ~Sarah Orne Jewett

Slime Time

We haven’t had much rain here this summer but all it takes is a thundershower, a good hot day and plenty of humidity to get slime molds on the move. And they really do move; through a process called cytoplasmic streaming slime molds can reach speeds of up to 1.35 mm per second, which is the fastest rate recorded for any micro-organism. Scarcity of food is what drives them on, always searching for bacteria and yeasts to feed on. As this photo shows slime mold plasmodium is a mass of glistening vein-like material (actually a single-celled amoeba) that creeps across dead leaves, wood, or soil. I think this might be the many-headed slime (Physarum polycephalum.)

I think this might also be the many headed slime (Physarum polycephalum,) even though it looks quite different than the previous example. When slime molds run out of food and come together into a mass like that pictured above, individual cells change their shape and can form stalks that are capped by fruiting bodies. A fruiting body can look like a jellybean or sphere, or can sometimes resemble blackberries, hair, dripping wax, and just about any other shape imaginable. The fruiting bodies produce spores that are borne on the wind and which will create new slime molds.

How big are slime molds? It varies, but tiny is usually a good description. I always carry my glasses and a loupe when I’m looking for them.

Some slime molds can grow big enough to be seen without too much difficulty. When the weather is right I look for what appear to be white or colored smudges on logs, leaves, or even mossy stones. Slime molds seem to grow on just about anything; there is even a photo online of one engulfing a beer can that was left out on a rock. They almost always grow on the side away from the sun because they don’t want to dry out. This one was growing on the top of a well-rotted log and that tells me that this log doesn’t see much sunlight.

If you want to photograph slime molds you’d better have a macro lens. What is seen in this photo wouldn’t have even covered Abe Lincoln’s head on a penny. I think it might be white finger slime (Ceratiomyxa fruticulosa, variety fruticulosa.) Identifying slime molds can be tricky, but most good mushroom books will include a section on them and there are a few good online resources as well.

 

The secret to finding slime molds is to walk very slowly and keep your eyes to the ground, scanning right and left as you go. I almost walked right by this one growing on a mossy boulder. Comparing it to the leaves and pine needles shows how small it was.

Looking through a macro lens shows the individual bodies of the slime mold on the stone in the previous photo. I’ve never seen this one but I think it might be Didymium iridis. If it is each tiny body grows on top of a hair thin black stalk. Calcium carbonate crystals give the fruiting bodies a light bluish, powdery appearance.

This organism has me completely baffled. I first saw one last year and it reminded me of a mass of tangled fishing line. This year I stumbled onto a spot where many of them grew in the leaf litter on the forest floor. Each mass was about pear size.

This is a closer look at the whatever-it-is in the previous photo. I don’t know if it’s a slime mold or fungus and haven’t been able to find a photo or description of anything similar. I keep forgetting to feel it and tug on one of the many threads.

Wolf’s milk slime mold (Lycogala epidendrum) starts out as tiny pink globules but as they age and become more like what we see in the above photo the globules look more like small puffballs growing on a log.

I think there are actually two slime molds in this photo. The two small black-brown shiny spheres could be Trichia decipiens, which are often found mixed in with other slime molds.

Wolf’s milk slime mold is also called toothpaste slime and that’s because there is a pinkish orange material inside each globule with the consistency of toothpaste. It can also have a more liquid consistency, which is usually the way I find it. As it ages it will turn into a mass of brown powdery spores.

One of the most common slime molds is the scrambled egg slime (Fuligo septica.) It gets quite big and will grow in full sun on wood mulch or chips, so it is easily seen and is often people’s first introduction to slime molds. Fuligo also septica produces the largest spore-producing structure of any known slime mold.

I wasn’t sure if this was a slime mold or not but I found some similar examples on line that said they were Lindbladia tubulina slime mold, which apparently has no common name. This one was somewhere between gunmetal gray and black, and about as big as a pear. It is described as cushion shaped and likes to grow on dead conifers, just as this one was doing.

A close look at the surface of Lindbladia tubulina shows thousands of tiny shiny spheres. The outside was crusty but inside where the spores are produced is said to be spongy and yellow or olive green. This type of surface is said to be bullate, which means “covered with rounded swellings like blisters.”

I don’t really know if this was a slime mold, fungus, or something else but since blue is my favorite color I was happy to see it. It was about as big as a penny.

Nature will bear the closest inspection. She invites us to lay our eye level with her smallest leaf, and take an insect view of its plain. ~Henry David Thoreau

Beauty in the Dark

We’re really getting a taste of high summer now with frequent thunderstorms, 90 degree temperatures, and high humidly. As soon as that happens I start thinking about fungi and slime molds because those are the conditions that many of them prefer. Unfortunately slime molds can be difficult to identify and, even after hours of looking through books and online, I still can’t identify the tiny transparent slime mold in the above photo. Some slime molds start life transparent and then change both their shape and color, which doesn’t help. They also often grow in very dark places, so some of these photos were taken under LED light.

 

The reason slime molds interest me is because they are very beautiful, and also fascinating. Nobody really seems to know exactly how they move, but they do. When the microorganisms that they feed on become scarce, many of these single celled organisms meld together and move toward food as a single entity. The white finger slime (Ceratiomyxa fruticulosa var. fruticulosa) in the above photo reminded me of a bed of kelp under the sea, all swaying in unison to the pull of a tide only they can feel.

 

I’ve never seen this slime mold before and I was surprised to see the tiny gray starbursts, which must have been 1/16 of an inch or less, when I looked at the photo. I couldn’t see them in person because they were too small. I haven’t been able to identify them but I think that they are beautiful things. This photo was taken with the aid of an LED light.

As slime molds go, this many headed slime (Physarum polycephalum) is usually large and easy to see. This one covered the base of a tree. It was in its plasmodial stage and on the move. This photo was also taken with the aid of an LED light.

According to Wikipedia “a plasmodial slime mold is enclosed within a single membrane without walls and is one large cell. This super cell (a syncytium) is essentially a bag of cytoplasm containing thousands of individual nuclei.” Slime molds aren’t plants and they aren’t fungi. They come closer to being amoebas than anything else and are believed by some to have simple brains. My question is, how do they know what the others are “thinking?” They seem to have the same “group think” abilities as a school of fish or a flock of birds, and that is quite amazing.

No need for LED with this scrambled egg (Fuligo septica) slime mold. It is one of a handful that can be found in full sun. The example in the photo is in its spore bearing phase and has formed a mass called an aethalium. Once it has released its spores and completed its life cycle it begins to darken and degrade into a dark red liquid that resembles blood, which can also be seen in the photo. This slime mold feeds on wood and is often found in mulch beds. This one was on a white pine stump.

One of my favorite shapes in the slime mold world is found in these honeycombed, dome shaped fruiting bodies of coral slime (Ceratiomyxa fruticulosa var. porioides). They are so small and delicate that one swipe of a finger could wipe out hundreds of them. To find them I look at logs after a rain; to the naked eye they look like white powder on the side of the log. Luckily a shaft of sunlight lit this area enough so I didn’t have to use artificial lighting for this photo.

In this photo, also in natural light, it looked like individual coral slime plasmodia were moving together to form a single mass. Slime molds can reach speeds of up to 1.35 mm per second, which is the fastest rate recorded for any micro-organism.

Slime molds aren’t the only tiny things that like to grow in dark places. I had to use a flash to get a shot of these yellow coral fungi (Ramariopsis laeticolor.) Each one was no bigger in diameter than a piece of cooked spaghetti, and they stood all of a quarter inch high.

I should say that, though slime molds and fungi like growing in dark places everything needs at least some light, and as I wandered the forest getting some of these photos one morning, I noticed that shafts of cool morning sunlight fell directly on or very near where they grew. Just because we may find them growing “in the dark,” and even though they don’t photosynthesize, that doesn’t mean that they don’t get an hour or two of sunlight each day. Sunlight also brings warmth and as I’ve studied fungi and slime molds over the years I’ve wondered if the reason they grow in a shaft of sunlight is because the soil is warmer there.

Dead man’s fingers (Xylaria polymorphaare) are a type of fungi that often look like a human finger. This one growing out of a crack in a beech log didn’t, but that was because it was a young example. They change their appearance as they age. This one had water droplets on it.

As they age dead man’s finger fungi begin to darken. The lighter areas are covered with spores that are produced in early stages of their development. These fungi cause soft rot in the wood they grow on. Insects or slugs seem to love them, judging by the damage on these examples.

In the final stages of their life dead man’s finger fungi darken until they turn black, and then they simply fall over and decompose. These examples grew at the base of a maple stump. It doesn’t take a very vivid imagination to see what almost look like fingernails on a couple of them. Maybe I should have saved these photos for Halloween.

 

Even on its lowest setting the LED light I use to photograph mushrooms and slime molds casts a shadow, so I use tissue paper as a diffuser to make the light softer. This photo of these little pinwheel mushrooms (Marasmius rotula) shows what happens when I forget the tissue paper. I’ve been trying to think of a way to eliminate the tissue paper altogether but so far haven’t had any brilliant ideas.

Witches butter (Tremella mesenterica) comes to life when it rains and can swell up dramatically from the hard, dark orange flake form that it takes in dry weather. I find this jelly fungus on tree limbs but it can also be a parasite on other types of fungi. The tremella part of its scientific name comes from the Latin tremere which means “to tremble,” and it does tremble just like gelatin. The mesenterica part of the scientific name is a combination of the Greek mesos, meaning “middle” and the prefix entero meaning “intestine.” Though the example in the photo doesn’t show it, the shape of this fungus often looks quite intestinal.

This is an excellent example of why we should pay attention to scientific names. The description provided by the scientific name of this fungus describes it perfectly in every detail, whereas “witches butter” tells us absolutely nothing, except maybe that the folks who roamed medieval forests were highly superstitious.

These are the largest split gill fungi (Schizophyllum commune) that I’ve ever seen; easily 3/4 of an inch across. The “gills” on the split gill fungus are actually folds on its underside that split lengthwise when it dries out. The splits close over the fertile surfaces as the mushroom shrivels in dry weather. When rehydrated by rain the splits reopen, exposing the spore-producing surfaces to the air, and spores are released. Split gills grow on every continent except Antarctica and are said to be the most studied mushrooms on earth.

This hot humid weather brings out other creatures too. I’ve seen pink slugs eating fungi many times, but this one leaned more towards yellow-orange and must have been 2 inches long. It was quite dark where it was so I had to use the flash. Slug identification seems close to impossible, at least for me, so I can’t tell you its name.

Beauty is certainly a soft, smooth, slippery thing, and therefore of a nature which easily slips in and permeates our souls. ~Plato

Slime Time

I showed two or three examples of slime molds in an earlier post but since then I’ve been seeing them everywhere and have to do something with all the photos, so here they are. Slime molds fascinate me because of their almost endless variety of shapes, colors and forms. They can be hard to find sometimes because they avoid sunlight and grow only in dark places. This means that photographing them can be challenging, but it can be done. Slime molds can also be very beautiful in my opinion, so I’m going to try to go easy on the scientific jargon and just let you enjoy looking at them.

 

Some slime molds can be very small and others quite large. This one in its plasmodium stage was easily as big as a dinner plate. When slime molds are in this state they are usually moving-very slowly. Slime molds are very sensitive to drying out so they usually move at night, but they can be found on cloudy, humid days as well. I think this might be many headed slime mold (Physarum polycephalum.)

 

This photo shows how slime molds, even though sometimes covering a large area, are actually made up of hundreds or thousands of single entities. These entities move through the forest looking for food or a suitable place to fruit and eventually come together in a mass. I think this one might be spreading yellow tooth slime (Phanerochaete chrysorhiza.)

 

These are the “teeth” that make up the spreading yellow tooth slime mold in the photo above. They are fruiting bodies that will release spores produced on their surfaces. These fruiting bodies are so small that they are rarely able to be seen with the naked eye.

 

From a distance this slime mold looked like any old gray, fuzzy forest mold, but as I got closer I saw that it was actually thousands of very thin filaments. I’ve never seen anything like it and can’t find it in books or online.

This is a close up of the slime mold in the previous photo. It looks like a pile of tangled fishing line, but each filament looked smaller in diameter than a human hair. I don’t know what benefit there would be to a living thing taking this form, unless it is to increase its surface area. It is certainly one of the oddest things I’ve ever seen in the woods and if I hadn’t seen it for myself I think I’d have a hard time believing that it was alive.

 

I’ve seen photos online of slime molds very similar to this one but the people who took the photos didn’t have any more luck identifying it than I did. For now all I can say is that it is a white slime mold, possibly a Physarum, in the plasmodium stage. I had to use a flash for many of these photos because of the cloudy day and forest darkness.

 

I think this might be another example of spreading yellow tooth slime (Phanerochaete chrysorhiza.)

 

This is another white slime mold in its plasmodium stage. Its name and species are unknown to me, but I think this one is very beautiful-almost like coral that has somehow escaped the sea.

This one won’t win any slime mold beauty contests that I happen to be judging, but it is unusual and the only example of the kind that I’ve seen. I think it might be chocolate tube slime mold (Stemonitis splendens.) The many tiny filaments were hanging from the underside of a log.

 

I showed a photo of this white finger slime (Ceratiomyxa fruticulosa var. fruticulosa) a post or two ago but I’m seeing it everywhere and I like it.

 

I think this might be dog vomit slime mold (Fuligo septica.) That’s an unfortunate name for a very interesting bit of nature. In the plasmodium stage this slime mold is transparent before it goes on to become a sponge-like mass called an aethalium, which is pictured here. An aethalium  is a “large, plump, pillow-shaped fruiting body.” This is also called scrambled egg slime mold because in Mexico, when it is in its plasmodium stage, it is collected and eaten like scrambled eggs. This is usually done on nights with the light of a full moon so the transparent plasmodium can be more easily seen.

 

I think that this is another example of Fuligo septica. At this stage the slime mold forms a hard crust that eventually degrades and darkens in color prior to releasing its spores.

 

This photo shows the darkening process of Fuligo septica just starting.

 

One of the most interesting things about slime molds is the many colors that they come in and how they can change color and form seemingly at will. When some slime molds dry out they become similar to powder on dry leaves. I see this most often with yellow and orange slime molds, but here it has happened with a blue one.  Slime molds can be almost any color. Yellow and white seem to be most common but they can also be green, pink, purple, blue, red, orange, brown, and black.  Part of the fun of slime molds, for me, is trying to find all the various colors and shapes. This is only the second time I’ve seen blue.

I hope you find slime molds as beautiful and fascinating as I do. If so, the next time you walk in the woods after a rain on a humid summer day, look a little more carefully in those dark places that you wouldn’t expect anything to be growing in. You might be surprised by what you find.

I love nature, I just don’t want to get any of it on me.~ Woody Allen

Beauty From Small Dark Places

We’ve had a lot of rain here in southwestern New Hampshire over the last two weeks and all of the sudden the dark places in the forests are showing some color.

 

There is a mushroom called Caesar’s mushroom (Amanita caesarea,) so why shouldn’t there be one called false Caesar’s mushroom (Amanita parcivolvata)? I think that’s what this one is but even after reading through three mushroom guide books I’m still not 100% sure.

 

 Violet toothed polypore (Trichaptum biformis) looks a little like turkey tail fungus (Trametes versicolor,) and I’m fairly certain that I have misidentified it as such here on this blog. Once you get to know the two though, it’s obvious that the purple edges on these are not found on turkey tails. I wish I had taken a photo of the undersides of these as well because it is supposed to be a beautiful lilac purple color and that’s something I’ve never noticed before.

 

A slug was feeding on this mushroom.

 

I know that slugs and snails are two different critters but there was a perfectly good shell sitting empty on this leaf that the slug in the previous photo might have been happy to have known about.

There is a wasp called the cicada killer (Sphecius speciosus,) but I’m not sure if this is one because their yellow stripes seem to be wider than those on this example. I’m also not sure if the other insect is a cicada. As I was putting this post together I heard about a wasp that is being considered to provide biological control of the emerald ash borer. Emerald ash borers kill ash trees and we have an infestation of them here in New Hampshire but again, I don’t know if the wasp in the photo has killed one or not. This photo asks more questions than it answers, so I’m hoping that someone reading this will be able to answer them.

 

I’ve never seen as many Indian pipes (Monotropa uniflora) as I have this year, including some very large colonies of them. My guess is they love heat, humidity and rain-all of which we’ve had plenty of lately.

 

 Horsehair mushrooms (Marasmius rotula) fruit on rotting wood, but I found these growing on the base of a living tree. These tiny mushrooms have caps no bigger than the diameter of a pea that sit on black stalks that are half the diameter of a pencil lead. They like dark, moist places and can be very tough to get a good photo of.

The pine needles scattered around this mushroom show just how small it is. Xeromphalina cauticinalis mushrooms fruit on debris found under conifers, and that’s just where this one was growing. This mushroom is supposed to be a western species that is only occasionally found in the east.

 

You can tell that it has been rainy, hot and humid when slime molds start to appear. Despite the name slime molds aren’t molds and they aren’t always slimy. Unfortunately, though everybody argues about what they aren’t, nobody seems to know exactly what they are. The easiest way for me to think of them is as a single celled organism like an amoeba, with thousands of nuclei.

No matter how you choose to classify them, slime molds can be very beautiful things, as the honeycomb coral slime mold (Ceratiomyxa  fruticulosa  var. porioides) in the above photo shows. When conditions are right and food is running low this organism will produce the white honeycomb shapes seen in the photo. They do this prior to fruiting, which is when they create the spores needed to reproduce. Without magnification this slime mold looks like a white smudge on a log and is far too small for me to see in any great detail. I’m always surprised when I finally see what is in the photos.

White finger slime (Ceratiomyxa fruticulosa var. fruticulosa) is a good description of the way this slime mold appears. It’s hard to relate just how small these are, but in each ‘finger” would be less than the diameter of a toothpick, and in length possibly 1/16th of an inch. As if that didn’t make photographing them tough enough sunlight is an enemy of slime molds, so they are only found in very dark places like the undersides of logs.

 

This sow bug, which also called a wood louse, helps show just how small slime molds are.

 

 Many headed slime mold (Physarum polycephalum) likes decaying organic matter like leaves and logs because this is where it finds its food supply of bacteria, yeasts, mushroom spores and microbes. The slime mold in the photo is in a vegetative phase called plasmodium, which is when it can move by ”streaming ” at about 1 millimeter per hour. The plasmodium is made up of networks of protoplasmic veins and many nuclei which move to seek out food. Once it finds something it likes it surrounds it and secretes enzymes to digest it.
