Posts Tagged ‘White Finger Slime Mold’

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

1. Many Headed Slime

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.)

2. Many Headed  Slime

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.

3. Slime Mold

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.

4. Slime Mold

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.

5. White Finger Slime

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.

 6. White Slime on Rock

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.

7. White Slime on Rock Possible Didymium iridis

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.

8. Unknown

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.

9. Unknown 2

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.

10. Wolf's Milk Slime Mold

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.

11. Wolf's Milk Slime Mold

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.

12. Scrambled Egg Slime Mold

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.

13. Lindbladia tubulina 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.

14. Lindbladia tubulina Slime Mold

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.”

15. Unknown

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

1. Transparent Slime Mold

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.

 2. White Ceratiomyxa fruticulosa Slime Mold

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.

 3. White Slime Mold

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.

4. Yellow Many Headed Slime Mold

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.

5. Weeping Fuligo septica Slime Mold

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.

6. White Ceratiomyxa fruticulosa Slime Mold

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.

7. White Ceratiomyxa fruticulosa Slime Mold 2

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.

8. Yellow Coral Fungi aka Ramariopsis laeticolor

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.

9. Dead Man's Finger aka Xylaria polymorpha

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.

10. Dead Man's Fingers aka Xylaria polymorpha

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.

11. Dead Man's Finger aka Xylaria polymorpha

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.

 12. Marasmius rotula Mushrooms

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.

13. Yellow Jelly Fungus

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.

14. Splitgill Mushrooms

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.

15. Unidentified Slug

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

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.

 1. Large Yellow Many Headed Slime Mold

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.)

 2. Yellow Tooth Slime Mold

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.)

 3. Yellow Tooth Slime Mold Closeup

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.

 4. Unknown Gray Slime Mold

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.

5. Closeup of Slime Mold

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.

 6. Unknown White Slime Mold

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.

 7. Possible Yellow Tooth Slime mold

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

 8. Unknown White Slime Mold

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.

9. White Slime Mold

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.

 10. White Finger Slime Mold

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.

 11. Fuligo septica Slime Mold

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.

 12. Yellow Fuligo septica Slime Mold

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.

 13. Fuligo septica Slime Mold

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

 14. Blue Slime Mold

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

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.

 1. Orange Mushroom

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.

 2. Purple Edged Bracket Fungi

 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.

 3. Slug on a Mushroom

A slug was feeding on this mushroom.

 4. Snail Shell

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.

5. Unknown Wasp

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.

 6. Indian Pipes

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.

 7. Horsehair Mushrooms on Tree

 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.

8. Tiny Brown Mushroom

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.

 9. White Honeycomb Slime Mold

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.

10. White Finger Slime Mold

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.

 11. Yellow Slime Mold with Sow Bug

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

 12. Many Headed Slime Mold

 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.

Only spread a fern-frond over a man’s head and worldly cares are cast out, and freedom and beauty and peace come in.  ~John Muir
