Posts Tagged ‘Coral Slime Mold’

 

Two or three years ago I saw my first pale beauty moth and now I’m seeing them everywhere. Their wings and body are pale greenish to grayish white and the female, which I think this example is, is said to be much larger than the male. The caterpillars are said to feed on the leaves of 65 species of trees and shrubs including alder, ash, basswood, beech, birch, blueberry, cherry, fir, elm, hemlock, maple, oak, pine, poplar, rose, spruce, larch, and willow. They’re supposed to be nocturnal but I see them in daylight. Usually in the evening though, so maybe they come out early.

There are a lot of dragonflies about this year and for some reason many of them are on lawns. I’ve walked over lawns and had hundreds of them flying around me. I can’t think of another time I’ve seen this but it must be that they’re finding plenty of food on the lawns. Or something. This example of what I think is a female widow skimmer (Libellula luctuosa) was near a pond on a cattail leaf, but there are lawns nearby. There were light whitish spots outside the dark spots on the wings but I think the lighting hid them.

 

A black ant was so interested in something it found on a sarsaparilla leaf (Aralia nudicaulis) it let me get the camera very close. I couldn’t see what attracted its attention and can’t tell from the photo either, but it was rapt. I think it was a common black house ant. It didn’t seem big enough to be a carpenter ant.

While I was visiting with the ant a winter dark firefly (Ellychnia corrusca) flew down and joined us on the same sarsaparilla leaf. According to Bugguide.net, these fireflies can be a pest in sap buckets in the spring because they like maple sap, and they will also drink from wounds in maple trees. They like to sun themselves on the sunny side of trees or buildings, but this one seemed happy just being on a leaf. Most fireflies live as larvae in rotting wood and forest litter near water and stay in the area they were born in, even as adults. They like it warm and humid, so they must be happy right now. They don’t seem to be afraid of people at all; I’ve gotten quite close to them several times.

On a very windy day what I believe was a male calico pennant dragonfly (Celithemis elisa) clung to the siding of a building. The light wasn’t right for dragonfly photography but I tried anyway and though it isn’t a great shot you can see most of the wing markings. These dragonflies are used to being blown about on the tips of twigs like a pennant, and that’s where their common name comes from. A fact that I find interesting about this dragonfly is how the males are not territorial and often perch facing away from water, apparently waiting for females as they approach the water. I’m not sure why this one chose a building.

NOTE: Blogging friend Mike Powell has pointed out that this is a female calico pennant dragonfly. If you’re interested in dragonflies or any other natural wonder, you should be reading Mike’s blog. You can find a link right over in the “Favorite Links” section of this blog. Thanks Mike!

I’m lucky enough to work near a pond and as I drive to work, early in the morning on a certain day in June, the snapping turtles begin to lay their eggs. As if someone flipped a switch the sandy shoreline between the pond and the road will be lined with the big turtles, sticking half out of the sand. And they are big; snapping turtles can weigh between 10-35 pounds. Though some snappers have been found as far as a mile from water most will dig their nest closer to it. They’ve been known to nest in lawns, gardens, and even muskrat burrows. Snapping turtles reach maturity at 8 to 10 years and can live up to 40 years or more.

It is said that some turtles weep from the strain of egg laying but this one had dry eyes. In fact she looked like she was smiling. You can see her beak in this photo; it has a rough cutting edge that is used for tearing food. They have powerful jaws and the snapping beak is easily able to snap off a finger or toe, so it isn’t wise to get too close to one. They have a neck that stretches quite a distance and they can lunge at high speed, which is how they catch their food. Snapping turtles eat plants, insects, spiders, worms, fish, frogs, smaller turtles, snakes, birds, crayfish, small mammals, and carrion. Plants make up about a third of their diet.

Snapping turtles lay one clutch of eggs in May or June and unfortunately this photo shows how most of them end up. Out of a nest of 15 to 50 eggs most will be eaten by raccoons, skunks, or crows. Though I’ve looked in the sand near disturbed nests I’ve never seen a paw print, so I can’t say what animal is doing this. It doesn’t take much to harm the turtles; the eggs are very delicate and the turtle embryo can be killed if turned or jarred. As many as 90% of the nests are destroyed each year and as I think about it I wonder if that isn’t part of nature’s plan. If every egg in every nest on this small pond were to hatch it would be overrun by snapping turtles and they would quickly run out of food. It might be better for them to never be born than to slowly die of starvation, but I’m very thankful that it isn’t up to me to make that decision.

Nature has a way of ensuring the continuation of each species and I know that many snapping turtles survive because I see them in ponds and streams everywhere. Egg hatching takes about three months but it varies depending on temperature and weather conditions. If the nest isn’t disturbed the hatchlings dig their way out in August through October and head right for the water. In winter they hibernate in the mud at the pond bottom. I should say that there are laws against disturbing turtle nests in New Hampshire, so they are best left alone.

I’m guessing that this bullfrog was very happy that there were no snapping turtles nearby. Adult female bullfrogs have an eardrum (tympanic membrane) that is about the same size as the eye and on a male it is much larger than the eye, so I’d say this one was a female. Females don’t croak but there was a lot of croaking going on here on this day.

With such a rainy spring I’m surprised that mushrooms aren’t popping up out of the sidewalks, but I’m not seeing that many. I did find some little horsehair mushrooms (Marasmius rotula) growing on a log recently. These are very small things; the biggest one in this photo might be as big as a pea.

Horsehair mushrooms are also called pinwheel mushrooms. Their pleated and scalloped caps always make me think of tiny Lilliputian parachutes. The shiny, hollow black stem lightens as it reaches the cap and is very coarse like horse hair, and that’s where the common name comes from. They grow in small colonies on rotting logs, stumps, and branches. Their spore release depends on plenty of moisture so look for this one after it rains. In dry weather they dehydrate into what looks like a whitish dot at the end of a black stem, but when it rains they rehydrate to release more spores. They can do this for up to three weeks.

The underside of the horsehair mushroom’s cap also looks like a parachute, with gills spaced quite far apart for such a little thing. In the center the gills join to make a collar that encircles the stem.

Swamp beacons (Mitrula elegans) are interesting fungi that grow in water and I find them in seeps where water runs year round. They are classified as “amphibious fungi” and use a process called soft rot to decompose plant material in low-oxygen areas. Since they only decompose soft tissue they aren’t found on twigs or bark and this photo shows how they are growing out of saturated leaves. I’m sorry about the strange angularity of this photo but I was kneeling in mud when I took it, trying not to drop the camera into it.

Another common name for swamp beacons is “matchstick fungus” and that’s exactly what they remind me of because they are just about the size of a wooden match. This one had an elongated head on it though and didn’t look very match like. If you want to get shots of this fungus be prepared to get your knees wet. Mine were soaked.

Hot humid weather along with a rainy day or two always makes me want to start looking for slime molds and sure enough after a recent shower, I found some. 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. A slime mold is an amoeba and that says a lot about how very small they are, but luckily they group together and that makes them easier to see. When I look for them I look for a smudge of color on the shaded sides of logs or on last season’s leaves. The one seen here is in its plasmodial stage and is on the move. I think it might be one called the tapioca slime mold (Brefeldia maxima.)

Slime molds can appear in their single celled amoeba form but when I see them they are almost always massed or massing together as these were. This plasmodial slime mold, like many others, 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 can reach speeds of up to 1.35 mm per second, which is the fastest rate recorded for any micro-organism. Eventually they will shift from the growth to the fruiting stage, when they will release their spores. Slime molds do not like dryness, so most of this usually occurs at night or on damp, humid days after a rain.

Here’s another look at what a slime molds can look like from a distance. This could also be yellow, orange or red. When looking for slime molds it’s important to remember that hot sunlight dries them out, so they’ll be on the shaded sides and undersides of logs, on stumps, mossy rocks, and in the leaves on the forest floor in the darkest part of the forest where the soil stays moist.

Here’s a closer look at the slime mold in the previous photo. 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. If you want to photograph slime molds you’d better have a good macro lens because many are almost microscopic in size. What you see in this photo wouldn’t even cover a penny. A good LED light is also helpful. I think this example might be coral or white fingered slime mold (Ceratiomyxa fruticulosa.)

I think all slime molds are beautiful but this one really takes the cake. At least I think it’s a slime mold. I’ve found various examples of it for about three years now and I’ve spent that long trying to identify it with no luck. I haven’t found anything even similar to it online or in a book. I think part of the problem is it starts out looking like the white, blurry, bumpy mass in the lower left corner and then opens into the tiny blue starbursts seen above. What that means is it’s hard to know whether to search for a white or blue slime mold. I’ve tried both many times with no luck, so if you know its name I’d love to hear from you.

As I was walking through the woods one day something told me to look up and when I did I saw a young porcupine sitting on the crook of a branch. It let me get close enough for a couple of quick photos but I didn’t want to disturb it, so I left and let it be. Porcupines are herbivores and eat leaves, twigs, and green plants such as clover. They often climb trees to find leaves for food, and in winter they will eat the bark of some trees. They are shy, gentle creatures but unfortunately I see many of their kind run over on the roadsides. They roam at night a lot and can be very hard to see. This one was quite small; probably smaller than a soccer ball. Many Native American tribes used porcupine quills for decoration on their clothing but women in the Lakota tribe found a way to get the quills without harming the porcupine; they would throw a blanket over it and then pick out the quills that were stuck in the blanket.

I went to the Ashuelot River one recent evening and found it raging because of strong thunder showers we’d had the day before, but a duck had found a calm spot away from the chaos of curling whitecaps. The river was high too; that small island isn’t usually an island.

But the duck didn’t seem to care one way or the other. It splashed and preened and tipped up to eat and smiled serenely while the river raged on around it. There has to be a lesson for us all in there somewhere. After all, nature is full of them.

He who has experienced the mystery of nature is full of life, full of love, full of joy. Radiance emanates from the whole existence itself; it does not know the meaning of holding back. ~ Maitreya Rudrabhayananda

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
