Posts Tagged ‘Honeycomb Coral Slime Mold’

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

Last Friday I cut wood for most of the afternoon at work and come Saturday morning I wasn’t feeling very agile, so I decided to take an easy, gentle and very beautiful walk along the Ashuelot River in Keene. I think I must have been about 10 years old the first time I walked this trail and it has been one of my favorite places to go ever since. You really never know what you’ll see here and I think 9 times out of 10 I come back surprised at what I’ve seen.

The biggest surprise of this day was a few clumps of yellow flag iris (Iris pseudacorus) growing on the river bank. I’ve searched for this plant for many years and found it only in one other spot in the woods by a pond that was very difficult to get to, but now here it is, right out in the open. This iris is a native of Europe and was introduced in the mid-1800s as a garden plant. Of course it escaped and began to naturalize and was reported near Poughkeepsie, New York in 1868 and in Concord, Massachusetts in 1884. Today it considered highly invasive and its sale and distribution is banned in New Hampshire, though in my experience it is a rarity in this part of the state. It’s a beautiful flower but now I do wonder what the banks of the river might look like 50 years from now if the plants are left alone.

In places the riverside trail is about 4 people wide but most of it is more like 2 people wide. Though I have no proof I believe the original trail is thousands of years old; once used by the Native Americans who used to fish, hunt and camp here. Natives were known to populate the Keene area and a little further upriver a school was built a few years ago and many Native artifacts estimated to be somewhere near 12,000 years old were found.

American water horehound (Lycopus americanus,) with its purple leaves, grew along the bank of the river. An interesting fact about this plant is how the Native American Iroquois tribe considered it poisonous, but the Cherokees used it to treat snakebite in both people and dogs. Usually I find that a plant used medicinally by one tribe was used in much the same way by other tribes, but not this one. In modern times it is used by herbalists to treat a variety of ailments including anxiety and insomnia.

A hoverfly found an ox-eye daisy very inviting. One of its wings seemed a little skewed but it looked like it could fly with no problems.

Like the ribs of an ancient sunken ship the branches of a fallen tree rose up out of the river. I read recently that in June 24, 1819 the New Hampshire legislature granted permission for the river, from this point south to where it meets the Connecticut River, to be dredged for steamboat travel. A toll on the steamers would be no more than 50 cents per ton of weight. Locks were built and in November of 1819 the first steamer 60 feet long and capable of carrying 15 to 20 tons, arrived in Keene. The venture seemed promising for a few years but the arrival of the railroad finally dashed the hopes of those wanting to see steamboats traveling the Ashuelot. Thanks goes to Alan Rumrill, director of the Cheshire County Historical Society, for this interesting bit of historical knowledge. If I saw a riverboat floating on the Ashuelot today I think I’d have to be revived.

Recent rains and high humidity helped a slime mold to grow on a well-rotted log. This slime mold is called coral slime (Ceratiomyxa fruticulosa var. porioides) and it loves to grow on rotted logs after a rain.

Coral slime mold is a plasmodial slime, which means that it moves using cytoplasmic streaming, which is basically a contracting of “muscles” by all of the separate cells until they come together in a single mass. They then shift from the growth stage to the fruiting stage. Slime molds die if they dry out, so most of this usually occurs at night or on damp, humid days after a rain. One of the most fascinating things about slime molds is how they move. They are thought of as a giant single cell with multiple nuclei which can all move together as one at speeds of up to an inch per hour. 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 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 really quite amazing.

My daughter was with me on this day and she found a broken robin’s egg, so I’m guessing that mom and dad are keeping very busy these days. If what I’ve read is accurate they will feed the young until they learn how to feed themselves. That could take as long as a month.

Porcupine sedge (Carex hystericina) blossomed along the river. You can just see the tiny, almost microscopic wisps of whitish flowers at the pointed ends of some of the upper spiky protrusions (perigynia.) This plant is also called bottlebrush sedge, for obvious reasons. It’s very common near water and waterfowl and some songbirds love its seeds.

Daisy fleabane (Erigeron annuus) started blooming a while ago. This plant has a very long blooming period; I see them in early June blooming profusely and then sporadically through the following months, even into November. I usually find more of them in waste places but I see them just about everywhere I go. It is considered a pioneer species, meaning it is one of the first plants to grow in unused pastures, or cleared or burned areas. Woodchucks and rabbits will eat the leaves and stems. Native Americans made a tea from the plant which was used as medicine for digestive ailments. Fleabanes get their name from the way the dried plants repel fleas.

Deer tongue grass (Dichanthelium clandestinum) was getting ready to blossom in sunnier spots. I don’t suppose many people have seen a deer’s tongue but I have and the leaves of this grass really do look like one, so it’s a perfect name for the plant. This is a very course, tough grass that is common in waste areas, roadsides and forest edges. It can be very beautiful when its leaves change in the fall; sometimes maroon, deep purple or yellow, and sometimes multiple colors on one leaf.

Invasive multiflora rose (Rosa multiflora) grew everywhere out here and in this shot it is growing up a dead tree. I just featured this rose in my last flower post so I won’t say much about it, other than its fragrance was astounding.

Insects love multiflora rose and that is the problem with its invasiveness, because birds love the rose hips that pollinated flowers produce. But just try to stop it; the genie is out of the bottle and there is no stopping it or any of the other invasive plants that are in this country.

Luckily invasive plants haven’t choked out all of our natives. Here was a large colony of Indian cucumber root plants (Medeola virginiana,) all in bloom.

The 3 large styles of Indian cucumber root darken as they age. Each flower will become a shiny, inedible dark purplish black berry. Native Americans used Indian cucumber roots as food. As its common name implies, this plant’s small root looks and tastes a lot like a mini cucumber.

It was a beautiful day to be on the river, but the big puffy clouds in the distance reminded me that there was a chance of a real old fashioned thunderstorm. When I was a boy our house had a covered porch and I used to love sitting on it and watching thunderstorms as they rumbled by. I don’t have a porch now but I still love a good summer thunderstorm.

The seeds of the yellow pond lily plant (Nuphar lutea) were a very valuable food source to Native Americans, who ground them into flour. They also popped them much like popcorn, but unless the seeds are processed correctly they can be very bitter and foul tasting. The plant was also medicinally valuable to many native tribes. There were quite a few growing in this part of the river where the water was so still it hardly moved at all.

The little red bridge is my signal to turn and go back because not too far after it is a highway full of cars. Both my daughter and I were surprised by the time. What seemed like a relatively short walk had taken us hours, but that’s what happens when you become lost in the beauty of nature and start discovering things that you’ve never seen before; time is a very easy thing to forget.

My favorite photo of this day was of what I think is American eelgrass (Vallisneria Americana.) I love the hypnotizing way it moves and undulates in the current of the river. It is also called tape grass and water celery, and it is an important food for turtles and other aquatic wildlife.

The song of the river ends not at her banks, but in the hearts of those who have loved her.

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
