1-the-stream

There is a small stream near my house that I like to visit at least once in winter and I did so recently. Right now it looks lazy and placid, but I’ve seen it rise overnight into a raging, road eating thing that easily covered everything in this photo except the trees. Its name is Bailey Brook, I just found out the night before posting this, but according to the Maine Geological Survey a brook is just a small stream. On the other hand a stream is a small river or brook, so I’m just going to keep calling it a stream.

2-tree-moss

One reason I like to come here is to see my old friends the tree mosses (Climacium dendroides.) They’re beautiful little mosses that I never see anywhere else. They must like very wet soil because they grow right at the edge of the stream and are covered by water when the stream floods. In fact all of the plants you’ll see in this post are under water for at least a day or two each year. It is their shape that gives tree mosses their common name but it is their inner light that draws me back here to see them.

3-christmas-fern

Christmas fern (Polystichum acrostichoides) is probably the most common of our evergreen ferns. When seen at this time of year it is obvious that it has had its branches flattened by the weight of the snow because they splay out all over the ground. When the new fronds, or fiddleheads, appear in spring the previous season’s fronds turn yellow and then finally brown. The dead fronds then form a mat around the living fern that helps prevent soil erosion. This is a fern that doesn’t mind wet soil.

4-christmas-fern

Christmas fern is easy to identify by its leaflets that resemble little Christmas stockings. The narrow fine teeth that line the edges of the leaflets and the short leaf stalks can also be seen in this photo. It is said to be called Christmas fern because early settlers brought the green fronds inside at Christmas.

5-marginal-wood-fern-spore-cases

Marginal wood fern (Dryopteris marginalis) is another evergreen fern that also grows well here because it likes damp, shady places. Its spore bearing sori grow on the edges of the leaves and give this fern its common name. The sori are covered by a kidney shaped cap (indusium,) which is smooth. The cap comes off just when the spores are ready to be released, as it has done on at least two of these examples.

6-pine-sap-on-fern

The sticky sap from a white pine (Pinus strobus) had dripped on the upper part of the marginal wood fern’s frond. I decided to show it to you so you could see how white pine sap turns blue when it’s cold.

7-jelly-fungus

An orange jelly fungus (Dacrymyces palmatus) was drying out and had lost its transparency. Jelly fungi can absorb many times their own weight is water but when they begin to dry out they can shrink down to a hard dry chip the size of a toddler’s fingernail.

8-fungal-growth

I saw a fallen branch with some familiar looking growths on it, so I looked a little closer.

9-fungal-growth

The branch growths had me believing they were slime molds for a minute or two. They looked a lot like a slime mold called Ceratiomyxa fruticulosa v. porioides, which looks like tiny geodesic domes and loves to grow on rotting wood. But something wasn’t right; they were a little too big and they weren’t bright white like Ceratiomyxa fruticulosa. Them my right hand found something cold and jelly like on the branch.

10-fungal-growth

I think what my hand found was a milk white toothed polypore (Irpex lacteus.) This is a “winter” fungus that can appear quite late in the year. It is also a resupinate fungus, which means it looks like it grows upside down, and that’s what many crust fungi seem to do. Their spore bearing surface can be wrinkled, smooth, warty, toothed, or porous and though they appear on the undersides of logs the main body of the fungus is in the wood, slowly decomposing it. This is the first time I’ve seen the “birth” of this fungus.

11-winter-fungus

I saw an awful lot of fungi for a January day. I’m not sure what this one was but it was pleasing to the eye and reminded me of spring, and that was enough.

12-artists-conk

Artist’s conk (Ganoderma applanatum) grew on an old oak and wasn’t hard to identify. This bracket fungus gets its name from its smooth white underside, which is perfect for drawing on.  Any scratch made on the pure white surface becomes brown and will last for many years. I drew a farm scene on one more than 30 years ago and I still have it.

13-artists-conk

Artist’s conks are perennial fungi that get bigger each year. Older examples can be up to two feet across, but this one was closer to half that. I put my Olympus camera on it to give you an idea of how big it was. This fungus causes heart rot in a wide variety of tree species, so this living tree is doomed.

14-horsetails

Horsetails (Equisetum hyemale) rise like spikes from the forest floor. These ancient plants are embedded with silica and are called scouring rushes. They are a great find when you are camping along a stream because you can use them to scour your cooking utensils. Running your finger over a stalk feels much like fine sandpaper.

15-horsetail

In Japan horsetails are boiled and dried and then used to smooth wood, and are said to produce a finish superior to any sandpaper. Horsetails produce spores in their cone shaped tips, but the examples in this spot rarely grow them. I think the stripes on them will always remind me of socks.

16-woodpecker-tree

This tree is full of insects, probably carpenter ants, and the pileated woodpecker that made these holes knew it. Pileated woodpecker holes are almost always rectangular and very big compared to other woodpecker holes. These were quite deep as well.

17-bark-beetle-damage

Pine bark beetles (Ips pini) had a field day here, according to the evidence left behind on several fallen limbs. The look of a jagged saw tooth pattern means unfinished egg chambers.  Pine bark beetles kill limbs and trees by girdling them. This stops the movement of water and nutrients up and down the tree and the infected limbs or the entire tree will die. These beetles are small and range in size from about 1/10 to 1/4 of an inch in length, but they can do a lot of damage when enough of them are in a forest.

18-grape-tendril

Native river grapes (Vitis riparia) grow along the stream banks. These are old vines that grow well into the tree tops and the fermenting fruit makes the forest smell like grape jelly on warm fall days. I like looking at their tendrils. Sometimes I see beautiful Hindu dancers in their twisted shapes; other times animals, sometimes birds. This one took the shape of a heart.

River grapes are also called frost grapes, and their extreme cold tolerance makes their rootstock a favorite choice for many well-known grape varieties. They’ve been known to survive temperatures of -57 degrees F. (-49 C)

19-tangle

Bailey Brook gets its start in the Horatio Colony nature preserve in Keene, which was too far away to hike to on this day, so I stopped at this tangle of trees, brush and vines. Finding ways under, over, through or around snags like these can take a lot out of you. This stream completely dried up in last summer’s drought and I could have walked up its bed all the way to its source, but I didn’t. I’m happy to see it full pf water again.

If it weren’t for the rocks in its bed, the stream would have no song. ~Carl Perkins

1. Pine Bark Beetle Damage

Pine bark beetles (Ips pini) made an intricate design on a white pine (Pinus strobus) limb. These beetles are small and range in size from about 1/10 to 1/4 of an inch in length, but they can do a lot of damage when enough of them are in a forest. They feed on the phloem tissue just beneath the bark and if they girdle the branch it will die. Dead branches mean no photosynthesizing and eventually the tree will die. For those who have never head the term; girdling of a branch or tree happens when the phloem and bark has been cut around its diameter in a complete circle. Native Americans and then early settlers used girdling to remove trees from fields and pastures and it is still used by some today.

2. Reindeer Lichens

I saw a beautiful drift of gray and green reindeer lichens recently. This shrubby lichen gets its common name from the way reindeer and caribou paw through the snow to find and eat it. Reindeer lichen reproduces vegetatively by small growths called soredia that break off and grow new lichens under the right conditions. The soredia are carried by wind, water or animals. Reindeer lichens grow about .31 inches (8 mm) per year so it’s clear that this drift has been here for a very long time. They can live for a century or more and studies have shown that only boiling and radiation caused severe damage to them. There are many who believe that lichens are virtually indestructible and are therefore immortal.

3. Reindeer Lichen

Reindeer lichens remind me of corals that you would see under the sea. The grayish white color and the way that the branch tips all point in one direction tell me that this one is gray reindeer lichen (Cladina rangiferina.) I find the biggest colonies of this lichen along the edge of a pine forest, growing in a very thin quarter to half inch of dry sandy soil over granite bedrock. At times they get so dry that if you walk on them it sounds much like it would if you walked on potato chips. I’ve read that reindeer lichens produce a single new branch each year and that their age can be determined by counting the branches. The plants pictured must have been very old indeed. I’m glad that I didn’t have to count their branches.

4. Bittersweet in Tree

Oriental bittersweet (Celastrus orbiculatus) grew into the top of a tree and then found that it had nowhere else to climb so it massed in the tree top, and its bright red berries show that. Bittersweet is very persistent and will simply grow or hang back down until it reaches the ground and then creep until it finds something else standing vertical. As it grows the vine winds tightly around the tree trunk and doesn’t expand when the tree does, so its wire like strength will eventually strangle the tree. This is why its sale and cultivation are banned in New Hampshire.

5. Blueberry Stem Gall

Blueberry stem gall always reminds me of a kidney bean. This gall forms when a shiny black wasp called Hemadas nubilipennis damages a bud while laying her eggs on a tender shoot. The plant responds to the damage by growing a kidney shaped gall around the eggs, and this is where the larvae will overwinter before emerging as adults in the spring. This example was a highbush blueberry (Vaccinium corymbosum) but this wasp isn’t choosy and will also use lowbush plants (Vaccinium angustifolium.) The galls do no real harm to the plants.

6. Witches Broom on Blueberry

This witch’s broom on a highbush blueberry looked very red. It’s interesting that the highbush blueberry’s leaves turn a beautiful red in the fall and the stem galls and witch’s broom are also red. Why so much red present, I wonder. Witch’s broom is a deformity that causes a dense mass of shoots to grow from a single point. It’s not caused by an insect but by a fungus called Pucciniastrum goeppertianum. This fungus spends part of its life cycle on the needles of balsam fir (Abies balsamea) so bushes should never be planted near fir trees. When the fungus releases its spores and they land on the stems and leaves of the blueberry, the bush becomes infected. The fungus overwinters on the bush and in the spring again releases spores which will infect even more balsam fir trees, and the cycle begins again. The disease infects the entire plant so pruning off the witch’s broom won’t help. I’ve worked on blueberry bushes that have borne large amounts of fruit even though they had witch’s broom, so I’m not sure how much the deformity harms the plant. I think it’s more offensive to the eye than anything.

7. Waterlily Leaf in Ice

A water lily leaf was trapped in the ice just off shore in a small pond. It tugged at me and I thought it might make a fine picture, but it looked much better in person than it does here.

8. Hornet Nest

Do hornets care that what they build is so beautiful, I wonder?

9. Burl

There was a time that I thought I had some artistic ability and I’d sit for hours drawing and painting. One of the things I loved especially was pen and ink drawing, and that’s what this burl I found on an old tree stump reminded me of. It looked like a Da Vinci sketch in pen and ink with a colored wash over all to add some depth and character, and how beautiful it was. I think the old master himself would have been pleased to see it.

For those not familiar with burl; it’s an abnormal growth that grows faster than the surrounding tissue. Scientists don’t fully understand why it happens but burls are thought to grow on trees that have been weakened by stress or damage.  Once the tree’s defenses have been weakened insects and /or fungi can attack and cause the abnormal growth. Woodworkers make some very beautiful things from burl and prize burls highly. Bowls and other objects made from it can sometimes sell for thousands of dollars.

10. Wooly Aphids

I found this colony of wooly alder aphids (Paraprociphilus tessellatus) on an alder limb. These insects can be winged or unwinged and need both silver maples and alders to complete their life cycle. Eggs overwinter in crevices in the bark of silver maple trees. In spring, nymphs hatch and begin feeding on the underside of new leaves. In late May through July, they develop wings and fly to alder trees where they feed on twigs and begin reproducing. Soon the colony is composed of aphids in all stages of development and becomes enveloped in white, fluffy wax as seen in the photo. Some aphids mature, return to silver maple trees and mate. Each mated female lays only one egg, which once again starts the overwintering stage.

11. Wooly Aphids

Wooly aphids are sap sucking insects that secrete sweet honeydew on branches and leaves of plants. The honeydew attracts a fungus called black sooty mold. Since the mold only grows on the aphid honeydew and not the plant, it doesn’t harm plants. In fact the aphids will do far more harm. I’m not sure if the aphids with dots in this photo always look that way, if they haven’t grown the white waxy covering yet, or if they’ve lost the covering for some reason. They were very small; not even pencil eraser size.

12. juniper Berries

I love seeing juniper berries at this time of year. A waxy coating called bloom makes them a bright and beautiful blue. I always wonder how many gin drinkers know that the unique flavor in their drink comes from this plant’s fruits. Though they’re called berries, botanically speaking juniper fruits are actually fleshy seed cones. Unripe green berries are used to flavor gin and the ripe, deep purple-black berries are the only part of a conifer known to be used as a spice, often used on game like venison, moose and bear meat.

13. Unknown Fungi

Part of what I try to do on this blog is show the amazing and beautiful things that are tucked into virtually every nook and cranny of nature and, with nothing but a slower gait and a watchful eye, how easy they are to see. Walking along at a toddler’s pace and looking at logs is just how I found the unknown fungi in the above photo. I knelt to give them a closer look and saw that they were like nothing I’d seen. Finding unexpected beauty like this can take us to that higher place where time seems to stop for a while. Sometimes it’s hard to know how long you’ve been there but that’s okay; as Mehmet Murat ildan said: “If you are lost inside the beauties of nature, do not try to be found.”

14. Mushroom Mycelium

Mushroom mycelium grew on the bottom of a log where it made contact with the soil. It wept golden nectar and its many intricacies reminded me of distant cosmic nebulae where stars and planets are born.

He who does not expect the unexpected will not find it, since it is trackless and unexplored. Heraclitus of Ephesus
