Posts Tagged ‘Spyrogyra algae’

Keen observers of the flowers that bloom in spring probably noticed that there weren’t any coltsfoot flowers in my last post. That’s because I hadn’t seen any yet, even though I had been to every place I knew of where they bloom. Except one, I remembered; the deep cut rail trail in Westmoreland that the ice climbers call the “Icebox” has a lot of coltsfoot plants along the trail. So, though I wasn’t sure what I’d find, last Sunday off I went. What I found was where winter has been hiding. As the above photo shows there was still plenty of ice clinging to the man-made canyon walls.

But the ice was rotten and melting quickly. Ice this big can be very dangerous when it falls, so I don’t get near it. I thought it had been warm enough to melt all the ice and snow here but obviously I was wrong.

The opaque gray color is a sure sign of rotten ice. Ice is rotten when the bonds between ice crystals begin to break down because of air and dirt coming between them.

Water was literally pouring from the walls. The groundwater always seeps and drips here but on this day it was running with more force than I’ve ever seen so I think it was meltwater.

And then I saw this fallen ice column. It looked like a boat and was as big as one that would fit 5 people. If this ever fell on a person it would crush them, so I decided to turn back and get out of here.

The view further down the trail didn’t look safe at all with all the ice columns melting in the sunshine, and there was what looked like a pile of ice down there.

That’s what it was; a pile of huge ice chunks all across the trail. I know it’s hard to judge the scale of things in a photo but these ice columns are as big as trees. Actually there is a fallen tree over on the left.

Here’s a shot of some ice climbers taken in February to give new readers an idea of the size of this ice. Some of it is huge.

I think that part of the reason the ice columns fall like they do is because the water in the drainage ditches along the side of the trail erode their bases away, as can be seen in this photo.

Ice isn’t the only thing that falls here. Stones fall from the ledges regularly and I saw at least three fallen trees on this day. I’m reminded each time I come here how dangerous the place can be, but it is also a place where I can see things that I can’t see anywhere else.

One of the things I can’t see anywhere else is the great scented liverwort (Conocephalum conicum.) They grow here by the thousands and I’ve learned to expect them to look a little tattered and worn in spring, because most are covered by ice all winter. By June though they’ll all be a beautiful pea green. Another name for the plant is snakeskin liverwort, for obvious reasons. Its pores and air chambers our outlined on its surface, and that gives it a very reptilian look. In my opinion it is one of the most beautiful of its kind.

I decided to look a little closer at areas with no ice or leaning trees nearby and I’m glad I did because I saw many interesting things, like what I believe is yew leaved pocket moss (Fissidens taxifolius.) This little moss grows in very wet places on the ledges where water drips on it almost constantly. Pocket mosses get their common name from the way the lower lobe of each leaf curls around its stem to form a pocket. This example was a little beat up because it has also most likely been under ice all winter.

Grasses were just coming up in the drainage ditches that follow along each side of the trail. The beech leaf in the foreground will give you an idea of their size.

I saw a large patch of moss on part of a ledge.

It turned out to be Hedwigia ciliata, which is a very common but an uncommonly beautiful moss. It’s also called white tipped moss because its branch tips are often bright white. I usually see it on stones in full sun.

Seedlings were coming up among the mosses. I’m not sure what they are because they had no true leaves yet but I do know that Jack in the pulpit plants grow all along this section of ledge. Many different species of aster also grow on the stone. It reminds me of a radish seedling.

I found that green algae (Trentepohlia aurea) darkens when wet. This hairy alga is orange because of the pigment beta carotene hiding the green chlorophyll. It grows out of direct sunlight on the damp rock walls.

I thought I’d practice my photography skills by trying to get a shot of a stone filled with mica. It isn’t as easy as it sounds because each piece of mica is like a tiny mirror that amplifies the sunlight.

If I could have gotten closer to the ice columns I would have shown you that the ice comes in many colors here. One of the colors is a reddish orange and I believe that it comes from iron leaching from the soil and stone. The above photo is of a spot in the woods where a pool of water was. When the water evaporated it left behind the minerals it carried, in this case probably iron.

I saw this bubbly mass in one of the drainage ditches. I’m not sure but I think it’s some type of algae. It reminds me of the spyrogyra algae I saw a few years ago. That example was on a very wet stone outcrop and this one was in water. I’ve read that it is most abundant in early spring and that the bubbles come from trapped gasses. It isn’t something I see regularly.

I never did find any coltsfoot flowers to show you but there were plenty of other interesting things to see. I also never made it all the way to the old lineman’s shack because of all the fallen ice, but I did see a piece of it; this plank from it was being used as a bridge to cross the drainage ditch. I wish people wouldn’t keep pulling the old shed apart but I don’t suppose anything can be done about it.

Nature is never static. It is always changing. Everything is in a constant state of flux. Nothing endures. Everything is in the process of either coming into being or expiring.

1. Silver Maple Seeds

The beautiful fruits (samaras) of the silver maple (Acer saccharinum) start out their lives deep red with a white furry coat. When you see them beginning to form you have to check them frequently to catch them in this stage because it happens quickly and ends just as quickly. The mature seeds are the largest of any native maple and are a favorite food of the eastern chipmunk. Silver maples get their common name from the downy surface of the leaf underside, which flashes silver in the slightest breeze.

2. Ostrich Fern Fiddleheads

I joined a professional ostrich fern (Matteuccia struthiopteris) fiddlehead forager earlier to see where the ferns grow along the Connecticut River. There were many thousands of ferns there-so many that I don’t think a busload of people could have picked them all. I also saw some of the biggest trees that I’ve ever seen that day. Ostrich fern fiddleheads are considered a great delicacy by many and many restaurants are happy to pay premium prices for them at this time of year. I’ve always heard that ostrich fern is the only one of our native ferns that is safe to eat. They like to grow in shady places where the soil is consistently damp. They really are beautiful things at this stage in life.

3. Lady Fern Fiddleheads

Though I’ve heard that ostrich fern is the only fern safe to eat many people eat lady fern (Athyrium filix-femina) fiddleheads as well, and gourmet restaurants in Quebec will pay as much as $10.00 per pound for them. Both ostrich and lady fern fiddleheads are considered toxic when raw and should be boiled for at least 10 minutes, according to one chef. After they are boiled they are sautéed in butter and are said to hold their crispness. They are also said to have the flavor of asparagus, but more intense. Lady fern is the only one I know of with brown / black scales on its stalks.

 4. Cinnamon Fern Fiddleheads

Both cinnamon (Osmundastrum cinnamomeum) and interrupted ferns (Osmunda claytoniana) have wooly fiddleheads that taste very bitter and are mildly toxic. Some fern fiddleheads, like those of the sensitive fern, are carcinogenic so you should know your fern fiddleheads well before picking and eating them or you could get very sick. I’ve known the fern in the photo for a few years now and know that it is a cinnamon fern, but if I hadn’t seen its fertile fronds in the past I wouldn’t know for sure. The fertile fronds that will appear a little later on once reminded someone of a stick of cinnamon, and that’s how it comes by its common name.

5. Interrupted Fern

The interrupted fern gets its common name from the way its green infertile leaflets are “interrupted” about half way up the stem by the brown, fertile leaflets. The fertile leaflets are much smaller and their color makes them stand out even at a distance. This fern doesn’t seem to mind dry, sunny spots because that’s usually where I find them.

6. Interrupted Fern Fertile Frond

Though usually brown the fertile leaflets on this interrupted fern were bright green and I wonder if they change color as they age; I’ve never paid close enough attention to know for sure. In any event, the fertile leaflets are covered with tiny, round spore producing sporangia. They will release their spores through tiny openings and then the fertile leaflets will fall off, leaving a piece of naked (interrupted) stem between the upper and lower infertile leaflets.

7. Algae

Last year at about this time I found this greenish stuff seeping out of the rocks on a rail trail and, not knowing what it was, called it rock slime. It looked slimy but if you put your finger in it, it felt like cool water and wasn’t slimy at all. Now this year I seem to be seeing it everywhere, but still seeping out of rocks. Luckily last year our friends Zyriacus, Jerry, Laura, and others identified it as a green algae of the genus Spyrogyra.  Zyriacus said that some 400 species of this genus are known, and they thrive in freshwater. It’s great having knowledgeable friends-just look at the things we learn from each other!

 8. Beaver Tree

Beavers started cutting this tree, but they don’t seem to be in any hurry to see it fall because it has been this way for a while. The only part of the tree’s trunk they eat for food is the inner bark, called the cambium layer, so maybe they were just snacking.

9. Beaver Tree Closeup

A beaver’s teeth really do make it look like someone has been chiseling the tree. If they have a choice they’d rather tackle trees less than six inches in diameter but they can fell trees up to three feet in diameter. The Native American Cherokee tribe has a story that says that the beaver collects the baby teeth of the tribe’s children, and will give a child good luck in return for a song.

10. White Baneberry

White baneberry (Actaea pachypoda) has so much movement and interest in its spring shoots. They remind me of tiny bird claw-like hands and always make me wish that I had brought a pencil and a sketch pad so I could draw them. Later on this plant will produce bright white berries, each with a single black spot, and that is how it got the common name doll’s eyes.

11. Striped Maple Bud Opening

We’re having some unusual spring warmth and it seems to be speeding up events that normally take a few weeks. I took this photo of a striped maple (Acer pensylvanicum) bud breaking on April 30th. On May 10th I was taking photos of striped maple flowers. From no leaves to flowering in just 10 days seems quite remarkable to me.

 12. Shagbark Hickory Bud Break

As you walk the trails along the Ashuelot River you might see what look like large pinkish orange flowers on the trees and think gosh, what beautiful things. If you get closer you will see that the colors are on the insides of the bud scales of the shagbark hickory tree, and aren’t flowers at all. And then you might wonder why such beautiful colors would be on the inside of a bud where nobody could ever see them, and as you walk on you might find yourself lost in gratitude, so very thankful that you were able to see such a thing. And later on, you might wonder if this chance meeting might have been an invitation.

 13 Beech Bud

In the spring as the sun gets brighter and the days grow longer light sensitive tree buds can tell when there is enough daylight for the leaves to begin photosynthesizing, so the buds begin to break. Bud break is defined as “when the green tip of a leaf can be seen emerging from the bud” and this can be a very beautiful thing, as we just saw with the shagbark hickory. American beech bud (Fagus grandifolia) break is every bit as beautiful and begins when the normally straight buds start to curl, as in the above photo. The curling is caused by the cells on the sunny side of the bud growing faster than those on the shaded side. This creates a tension that curls the bud and eventually causes the bud scales to pull apart so the leaves can emerge. At the bud’s location on the tree branch an entire year’s new leaves and stems will often grow from a single bud.

 14. Beech Bud Break

Now we know how beech buds open, but who can explain why they’re so beautiful when they do? Maybe it’s just another invitation. These invitations come so unexpectedly. Art, music, the beauty of a leaf or flower; all can invite us to step outside of ourselves; to lose ourselves and walk a higher path, at least for a time. It’s an invitation which if accepted, can be life changing.

One who not merely beholds the outward shows of things, but catches a glimpse of the soul that looks out of them, whose garment and revelation they are–if he be such, I say he will stand for more than a moment, speechless with something akin to that which made the morning stars sing together. ~George MacDonald
