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.

Here are a few more of those out of the ordinary things that I stumble across in my travels.

 1. Beard Lichen

Like the bones of a prehistoric reptile or the ruins of an ancient castle, beard lichens (Usnea) always remind me of the great age and great mysteries of this earth. This one has become an old friend and I visit it often. Most lichens refuse to grow where there is air pollution, so seeing them is always a good sign.

2. Bubbkegum Lichen

Ground dwelling lichens like this bubblegum lichen (Icmadophila ericetorum) will become covered with leaves and harder to see before too long.  This lichen gets its common name from the bubble gum pink fruiting bodies.

3. Scattered Rock Posy Lichen

Scattered rock posy lichen (Rhizoplaca subdiscrepans) grows on stones in full sun, so it will be visible all winter long. This is one of my favorite lichens and one of the most beautiful, in my opinion.

4. Beechnuts

Beech trees (Fagus grandifolia) are dropping their ripe nuts now and I saw a few places last week where the forest floor was littered with them.  The chipmunks and squirrels have been busy though, so you find more empty husks than anything else.

5. Beechnut  Opened

If you harvest beechnuts and then leave them alone for a day or two they will open like the one in the photo, and out will drop two kernels. Like many trees and other plants, beech trees will have a year of heavy production, known as a mast year, and then produce very few nuts for a few years afterwards. Since most of the kernels I opened were empty I have to assume that this isn’t a mast year.

6. Wild Sarsaparilla Fruit

The black, shiny wild sarsaparilla (Aralia nudicaulis) berries are ripening. This year has been amazing as far as the bounty of nuts, fruits, and berries I’ve seen. I think the birds and animals will have a good winter with plenty to eat.

7. Polypody Fern Sori

Now is the time to turn over the leaves of the common polypody fern (Polypodium virginanum ) to see the naked spore capsules, which are called sori.  Most ferns have a flap like structure called an indusium that protects their spores, so being able to see them exposed like this is unusual. They always remind me of tiny round baskets full of flowers. The Druids though this fern had special powers because of its habit of growing near oak trees. Its roots and leaves have been used medicinally for many centuries and its name appears in some of the earliest herbal and botanical texts.

8. Cockleburrs

Common cocklebur (Xanthium strumarium) grows in every state except Alaska and throughout most of Canada. The spiny parts of the plant in the photo hide its tiny female flowers parts. Male flowers can be seen in the upper part of the photo, just to the right of center. I find cocklebur growing on riverbanks but it can also grow in agricultural areas. Since it can be toxic to livestock it isn’t a favorite of farmers and ranchers. Historically it has been used medicinally by Native Americans and was once used to make yellow dye.

9. Wild Cucumber Fruit

Young boys just need something to throw at each other (and rarely at young girls if they’re trying to get their attention) and it’s as if wild cucumber seed pods (Echinocystis lobata) were specifically designed for that purpose. The spines are scary looking but in reality are soft and aren’t really prickly until they are dried. This one reminded me of a small spiny watermelon.

10. Foxtail Grass

It’s not hard to see where green foxtail grass (Setaria viridis) gets its common name. This grass is a native annual that grows in clumps. Each bristle, called an awn, comes from a single grass flower and through natural rain and frost action burrows into the ground with the seed once it falls from the seed head. These plants are very dangerous to dogs and other animals because the awns, driven by the animal’s normal muscle movements, can burrow into their skin and cause infection and even death if not treated. Dog owners would be wise to rid their yards of any kind of foxtail grass.

11. Wooly Alder Aphid aka Paraprociphilus tessellatus

This colony of wooly alder aphids (Paraprociphilus tessellatus) on an alder limb was quite large. 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.

12. Water Lily Stems

I watched the sun come up over a local pond recently and it was at the perfect angle for lighting up water lily stems. Since this isn’t something I often see I thought I’d show them here. These leaf stalks are flexible and coil somewhat to allow for fluctuations in water depth.

13. River Rocks

I visited a different section of the Ashuelot River one day and found that someone had been stacking rocks. Some Native American tribes believed that stacked rocks were a spiritual method of protecting sacred spaces. They were often built near powerful energy sources like springs or places with high numbers of lightning strikes. Piles and stacks had many different shapes and sizes and each meant something different.

14. Old Red Oak Tree

This large red oak stood next to a trail I was following one day. It isn’t the biggest I’ve seen but it was big. I leaned my monopod against it to give an idea of its size. A small sign nearby said that its age is estimated to be 300 years, and that it probably was never cut because it grew on a stone wall. Stone walls are boundary markers here in New Hampshire and it is illegal to remove stones from them or alter them in any way unless they are on your land. I can picture the farmers on either side of the wall not cutting the tree because their neighbor might have claimed ownership. That’s the way we do things here-not wanting to bother our neighbor, instead of asking we wait and see, sometimes for 300 years.
