Posts Tagged ‘Bud scales’

I’ve met people who thought that buds appeared in spring just before the leaves came out but no, buds actually form in late summer, when trees begin storing reserves to help them get through winter. The period is called lignification and it happens when trees stop their active growth cycle. One of the ways to identify trees and shrubs in winter is by their buds. The size and placement of buds as well as the number of bud scales (cataphylls) can all help with identification. Bud scales are modified leaves that cover and protect the bud through winter. Some buds can have several, some have two, some just one scale called a cap, and some buds have none at all. Buds that have several scales are called imbricate and have scales that overlap like shingles. I’m starting this post with some unusual trees that aren’t often seen in this area, and the bud shown above is a sweet gum bud. It is a good example of an imbricate bud. It is also a good example of a rarity here.

Sweet gum trees (Liquidambar styraciflua) are easily identified by their unusual seed pods, above, and by the large size of their buds, which can be green, red or orange. I’ve read that Native Americans used the hardened resin from these trees for chewing gum. The resin was also used in a tea to calm the nerves and, when powdered and mixed with shavings from the tree, was used as incense by the Maya. The resin is said to look like liquid amber, and that’s where the first part of the scientific name, Liquidambar comes from.

Another tree you’ll have a hard time finding in this area is the European copper beech (Fagus sylvatica purpurea.) I’ve looked at its buds before in March and maybe they were swelling up to prepare for bud break, but they seemed bigger than those on our native trees. This year in January they really don’t look much different than our native beech buds. Long and pointed, they are a different shape than the sweet gum bud we saw but are still imbricate buds because of their shingle like, overlapping bud scales. They’ll open with maroon foliage, which over time will become a beautiful bronze / purple.

I love the bark on this old beech tree. It reminded me of an elephant’s skin. This tree lives on the grounds of the local college and there is another in Dublin, but otherwise I don’t know of any other European beeches in this area.

Tibetan cherry (Prunus serrula Tibetica) is another tree you might have a hard time finding but if you had studied your buds, you would recognize these big, shiny red buds as more imbricate buds. A gummy resin often fills any spaces between the scales and makes the bud waterproof. If water ever reached the bud and froze it could kill or damage it, so nature found a way to prevent that from happening. The shape of many imbricate buds also ensures that water will run off, rather than stay on the bud. Bud scales also help prevent moisture loss. These buds are very pretty, in my opinion.

The bark of a Tibetan cherry is very interesting. It is also called the paper bark cherry because of the way its bark peels as it ages, much like a birch. It is used as an ornamental tree as much for its bark as for its flowers, which are similar in shape and size to other ornamental cherries. The mahogany bark has very long, closely spaced lenticels that give it an unusual appearance. Lenticels are corky pores that allow gases like oxygen to reach the living cells of the bark. Without enough oxygen bark can die, so it “breathes.”

The most unusual tree bud to appear in this post is that of the ginkgo, which I find at the local grocery store, of all places. The short shoots bear terminal buds that are small at less than an eighth of an inch, with room for just two overlapping scales. A bud with only two overlapping scales is called two ranked. You can see how the terminal bud and many leaf scars are crowded together. Ginkgo is considered a “fossil tree” that has been on earth for millions of years. It is also considered the oldest living seed plant. It is said to be capable of living several hundred years, and there are trees in China that are thought to be at least 400 years old.

Buds with two scales that meet but do not overlap are called valvate buds, and a good example of a valvate bud can be found on nannyberry shrubs (Viburnum lentago). Though the scales in the photo do happen to overlap somewhat normally they would not, so they are still considered valvate. Nannyberry is one of our few native viburnums with edible fruit. They can get quite tall, almost the size of a small tree. According to the book The Origins of English Words “nannyberry” is also called sheep berry and that name comes from its fruit, which is said to resemble sheep droppings. The nanny part of the name comes from the nanny goat. Squirrels and birds are said to eat the fruit but I see huge numbers of them still on the bushes well into winter.

Cornelian cherry buds (Cornus mas) are also good examples of valvate buds. In the spring when the plant begins to take up water through its roots the buds swell and the two scales part to let the bud grow. What confuses me about this shrub is how the two outer scales never seem to be completely closed. It doesn’t seem to matter though because they always flower beautifully. Some bud scales like these are hairy and some are covered with sticky resin that further protects the bud. Cornelian cherry is an ornamental flowering shrub related to dogwoods. It blooms in early spring (in March) with clusters of blossoms that have small, bright yellow bracts.

One bud scale covering a bud is called a cap, and magnolia bud scales are good examples of that. Magnolia flower buds are described as “densely pubescent, single-scaled, terminal flower buds” and that’s what we see here. The hairy single scale will fall off when the bud inside has swollen to the point of blossoming. Once the plant flowers the ground under it will be littered with these hairy caps for a short time, so if you’d like to see one up close that’s the time to look.

I was lucky to find a seed pod on the magnolia that I looked at but unfortunately it was quite dry. I’d like to find a fresh one because I’ve read that they’re full of bright red seeds. I’ll look for one this spring to show you.

Big, black and pointed mountain ash buds (Sorbus americana) fooled me into thinking they had a single cap like bud scale at first, but they actually have several overlapping scales which are quite sticky. I finally got a photo that shows this. You have to look closely at buds to see what is really going on, so it helps to have a loupe or a macro lens.

The terminal buds on a Colorado blue spruce (Picea pungens) are oval shaped and imbricate with many bud scales. Sometimes the scales pull back from the bud (reflex) as these did, creating what look like tiny green flowers. In a way they remind me of the male flowers on a haircap moss, but of course they’re much bigger.

Here is a look at the side of the bud in the previous photo. Evergreen buds can be very sticky, but I’ve noticed that much more sap or resin flow occurs on warm days. On a cold day in January these buds were hardly sticky at all. You can also see the rows of whiteish breathing pores (stomata) on some of the needles in this shot. Carbon dioxide, oxygen, and water vapor enter and exit the tree through these tiny openings. There are many millions of them on a single tree.

If you see that some of the branches on your Colorado blue spruce are a bit deformed like those seen in the above photo your tree has the Eastern spruce gall adelgid living on it. They cause crab claw like galls but don’t do any real harm to the tree. I’ve had them on a tree in my yard for years now and it is still as healthy as the day I planted it. By the way, a blue spruce can be green.

If I had to choose a favorite tree bud the flower buds of the red maple (Acer rubrum) would have to be at the top of the list. They’re very beautiful but more than that, they are one of my first signals that spring has finally come. It doesn’t matter what the calendar says, when I see red maple flowers, I know winter is over. Of course sometimes they get a little over anxious and will get frost bitten, but more often than not they’re a reliable indicator. Each small flower bud has four pairs of bud scales.

Sugar maple terminal buds (Acer saccharum) appear on the end or terminus of a branch. The larger, pointed, very scaly bud is flanked by lateral buds on either side. The lateral buds are usually smaller than the terminal bud and the twigs and buds are brown rather than red like silver or red maples. These buds have imbricate bud scales and they show the whitish, sticky resin that “glues” one scale to another.

Norway maple (Acer platanoides) buds are also imbricate but instead of sticky resin on the edges of its bud scales they have a fringe of fine hairs which help shed water. These buds are relatively large and easy to study using a hand lens, so they’re perfect for children in the field.

Buds that have no bud scales but are very hairy like those seen on witch hazel (Hamamelis virginiana,) are called naked buds. The hairs take the place of bud scales when it comes to protecting the bud and it works well. Other naked buds are found on staghorn sumacs (Rhus typhina) and the native viburnum called hobblebush (Viburnum lantanoides).

Witch hazel flower buds are also very hairy, but rounder than its leaf buds. It won’t be long before the yellow or orange strap like flower petals appear on the spring witch hazels. It’s something I’m impatiently looking forward to.

I know that not everyone gets as excited over buds as I do but I also know that there are children who read these posts so I often have them in mind when I do a post like this one. I hope something like a post on buds might help jump start a child’s interest in nature. They aren’t that complicated and hopefully bud scale terminology won’t seem too intimidating.

If you are interested in learning about tree and shrub buds, start with one in your own yard that you are sure of, like a maple tree or even your rhododendron, and then branch out to those you don’t know well. The following information might help to get you started:

A bud scale is made up of modified leaves or stipules that cover and protect the bud in winter. Usually the number of bud scales surrounding a bud will help identify a tree or shrub.

Imbricate bud: A bud with numerous scales that overlap each other like shingles.

Valvate bud: A bud with two or three scales that do not overlap.

Two Ranked Bud: A bud with two scales that do overlap.

Caplike bud: A bud with a single scale that comes off in the spring.

Naked bud: A bud with no scales.

If you find that you have the itch to learn even more about buds and trees, this little book is for you. I’ve had my copy since I was a teen but it’s still in print. It is very helpful and easy to understand.

Must we always teach our children with books? Let them look at the stars and the mountains above. Let them look at the waters and the trees and flowers on Earth. Then they will begin to think, and to think is the beginning of a real education.  ~David Polis

1. Hazelnut Pods

I like the reds and orangey browns and the velvety texture of hazelnut husks. They add a nice touch of color to the gray and white world of winter. The nuts are a favorite of many birds and animals including turkeys and squirrels so they disappear quickly. This photo is of American Hazelnut (Corylus americana) but we also have beaked hazelnut (Corylus cornuta) in parts of the state.

2. Hobblebush Bud

This is the time of year that I start watching buds to see what they’re up to.  Hobblebush (Viburnum alnifolium) flower and leaf buds are naked, meaning they have no bud scales. Though there might be plenty of snow the ground is frozen, so none of the moisture is available to plants and bud scales help conserve moisture. Plants that have no bud scales have evolved other ways to protect their buds, and one of those ways is by wearing wooly winter coats like the hobblebush does.

3. Nannyberry Bud

Nannyberry (Viburnum lentago) buds always remind me of long beaked birds. This is another native viburnum but instead of being naked its terminal flower buds have two scales. They’re a good example of valvate bud scales, which simply means the margins of the two bud scales touch but don’t overlap. This shrub is easily confused with wild raisin (Viburnum cassinoides) in the winter because its flower buds are very similar, but the bud scales on wild raisin tend to split open more around the swollen part of the bud.

4. Striped Maple Buds

Striped maples (Acer pensylvanicum) have colorful twigs and buds and are among the easiest trees to identify no matter what time of year because of the green and white vertical stripes on their bark. Their terminal buds have two scales and are valvate like the nannyberry buds.

 5. Red Maple Buds

Red maples (Acer rubrum) protect their buds with as many as four pairs of rounded, hairy edged bud scales. The scales are often plum purple and the bud inside tomato red. This is one of the first of our native trees to blossom in spring and also one of the most beautiful, in my opinion. Each small bud holds as many as 6-8 red blossoms. Red maple trees can be strictly male or female, or can have both male and female blossoms on a single tree. They bloom before the leaves appear and large groves of them can wash the landscape with a brilliant red haze which shouts that spring has arrived.

6. Alder Catkins

This is also the time of year that I start to watch catkins for signs of pollen production. Before too long alder catkins will open their purple scales and burst with golden pollen, and the edges of ponds and streams will be draped with their dangling beauty for a short time.

7. Black Birch Male Catkins

Black birch (Betula lenta) catkins will do the same, but they aren’t quite as showy as alder catkins. Black birch twigs taste like wintergreen when they’re chewed so that’s how I make sure I have the correct tree. Black birch was once harvested, shredded and distilled to make oil of wintergreen, and so many were taken that they can be very hard to find now. I know where a few grow but they aren’t a common sight. Young trees are easy to confuse with cherry.

8. Black Knot aka Apiosporina morbosa on Cherry-3

Speaking of cherry, one day I saw several young trees with black knot disease. It is caused by the fungus Apiosporina morbosa which can also attack plums, peaches, and apricots. Spores from the fungus can be spread by rain or wind and typically infect trees from April through June on new growth. Infected stems swell up and produce hard black knots like those in the above photo. This disease can eventually kill the tree so infected limbs should be pruned off 2-4 inches below the knots and buried or burned before bud break the following spring.

9. Oak Gall Caused by Callirhytis quercussimilis

A gall wasp called Callirhytis quercussimilis caused this swelling on the trunk of this scrub oak (Quercus ilicifolia.) If the trunk had twisted just a bit differently it would have made a great cane.

 10. Cedar Seed Pods

The dried, open cones of northern white cedar (Thuja occidentalis) look like tiny, carved wooden flowers. Gone are the eight seeds that each one holds, but the flattened, scale-like leaves so common on cedars can be seen in this photo. Native Americans showed 16th century French explorer Jacques Cartier how to cure scurvy with the leaves of this tree and he was so impressed that he named it Arborvitae, which is Latin for Tree of Life. He also had trees with him when he returned to Europe, and Thuja occidentalis became the first North American tree to be introduced there.

11. Indian Pipe Seed Pod

Indian pipe (Monotropa uniflora) seed pods also look like tiny carved wooden flowers. Most have split open by now to release tens of thousands of seeds to the wind, but not this one. It has cracked open though and since the individual seeds are only ten cells thick, some have probably escaped.

12. Crust Fungus Steccherinum ochraceum

Fallen branches are great places to find lichens and fungi in the winter so I always take a closer look at them. This one had a large area of what I think was white rot fungus (Phanerochaete chrysorhizon) growing on it. This toothed crust fungus is a deep, orangey- brown and has folds that look like teeth.  It is very similar to the milk white, toothed polypore (Irpex lacteus) but that fungus has edges that curl.

13. Rimmed Camouflage Lichen aka Melanelia hepatizon Apothecia

I found this leafy (foliose) rimmed camouflage lichen (Melanelia hepatizon) growing on a white pine branch but it can grow on stone and is also called rock leather. Its body (thallus) is very dark olive green with brown and black here and there. Its fruiting bodies (apothecia) are rosy brown disk like structures with white ruffled edges that look as if they’d been dipped in powdered sugar.  These white bits are called Pseudocyphellae, which are pores in the body of the lichen that open to the medulla. The medulla is a layer made up of long, thread like structures called hyphae which in turn make up the fungal part of the lichen. If we revisit lichens 101 we remember that lichens are actually composite organisms that emerge from algae or cyanobacteria (or both) living among filaments of a fungus in a mutually beneficial (symbiotic) relationship. Phew. Some lichens can be almost as difficult to describe as they are to identify.

14. Orange Inner Bark

Though I enjoy finding things in nature that I’ve never seen before and love to learn all about them, sometimes I like to put away the books, forget all the big words and just enjoy the staggering beauty of it all. The unfurled bark of this tree limb showed its striking and unexpected colors that were hidden within, and it reminded me of how lucky I am to be able to see such things, and how very grateful I should be for the opportunity. After a whispered thank you for all of the wonderful things I had seen on this day I headed for home with a glad heart.

1. Stream Ice

This year winter seems determined to overstay its welcome and has brought record low temperatures and record high snowfall amounts. Even though we’ve had mini thaws where the temperature rose to 40 degrees for a day or two, most of the time we have been well below freezing during the day and below zero at night. Because of that the snow that has fallen is melting very slowly.

 2. Melting Snow

The snow in the woods is knee deep, which makes going rough. I recently bought some gaiters to keep my pant legs dry and make life a little easier, but another good storm will mean snowshoes for sure. One way to make it easier to get around is to look for south facing spots like that in the photo above where the snow has pulled back some. These are great places to look for mosses and other plants that stay green throughout winter.

 3. Fern on Ice

Ferns might look fragile but evergreen ferns like this intermediate wood fern (Dryopteris intermedia) aren’t. This one was growing in the midst of an ice sheet. There aren’t many ferns that are evergreen in New England so winter is a good time to hone one’s identification skills by getting to know them. This one is very similar to the marginal wood fern (Dryopteris marginalis). Both the words “intermediate” and “marginal” in the fern’s common names refer to the placement of the spore bearing structures (sori) found on the undersides of the leaves.

 4. Evergreen Christmas Fern

Another fern commonly seen in winter is the evergreen Christmas fern (Polystichum acrostichoides). This one 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. When seen at this time of year it is obvious that evergreen Christmas fern has had its branches flattened by the weight of the snow because they splay out all over the ground. Once new fronds emerge these will brown and die off.

 5. White Poplar Bark

Winter is also a good time to learn how to identify trees by their bark since there is no foliage in the way. A tree with light to dark, mottled gray bark with diamond shaped marks in it is a young white poplar (Populus alba). The diamond shapes are the tree’s lenticels, which are air pores. The bark on white poplars can be very white at times like a birch, but it is usually light gray when young. Older trees have darker gray, furrowed bark at their bases.  White poplar was introduced from central Europe and Asia in 1748. It can now be found in every state except Alaska, Arizona, and Hawaii.

 6. Hedwigia cillata Moss 

Mosses are easy to find in winter if you look at logs and stones where the snow has retreated. This Hedwigia ciliata moss with its white leaf tips is usually found growing on boulders and is very easy to identify. Common names include Hedwig’s fringeleaf Moss, Hedwig’s rock moss, and Fringed Hoar-moss. Johann Hedwig was a German botanist who studied mosses in the eighteenth century. He is called the father of bryology and lends his name to this and many other mosses.

 7. Slender Tail Moss aka anomodon attenuatus

This moss has never appeared on this blog in this dry state before. Long-leaved tail moss (Anomodon attenuates) is also called tree apron moss because it is quite common on the lower part of tree trunks. When wet its leaves stand out from the stem and it takes on a more feathery appearance and looks completely different than it does in the photo. This is a good example of why serious moss hunters do so after it rains.

 8. Moss aka Dicranoweissia cirrata

This is another first appearance on this blog. Curly thatch moss (Dicranoweissia cirrata) grows on rotting logs and stumps and is very small, with leaves that curl when dry. After a rain its leaves will straighten out and this moss will look very different than it does in this photo, which is why I’ve found it so hard to identify. Tiny growths on the leaves called gemmae are intended to break off to perpetuate the species.

 9. White Cushion Moss

White cushion moss (Leucobryum glaucum) can appear silvery, white, bluish green or grayish green but it always forms a thick cushion and stands out from the mosses that might surround it. It likes plenty of water and shade and grows on rotting logs or on stone when there is enough soil. It is probably the easiest of all the mosses to identify.

 10. Beard Lichen

March is a month known for its wind and anyone who studies nature can take advantage of that fact, because there are all kinds of things falling from the trees at this time of year. This beard lichen (Usnea) was lying on top of the snow and at 4 1/2 inches long is the longest I’ve ever seen. It is said that if you take a single strand of this lichen and gently pull it apart lengthwise you’ll find a white cord inside, but it must take extreme magnification to see it because I’ve never been able to.

 11. Gilled Bracket Fungus 

Another bracket fungus that mimics the common turkey tail (Trametes versicolor) is the multicolor gill polypore (Lenzites betulina).  Since turkey tails have pores and these have gills they are hard to confuse. Multicolor gill polypores start life very white but turn gray as they age. They have some zoning like turkey tails and are often covered with green algae.

 12. Gilled Bracket Fungus Closeup

This is an extreme close-up of the underside of the multicolor gill polypore in the previous photo. These are clearly not pores.

NOTE: Thanks to help from a knowledgeable reader and more experience identifying fungi I now know this to be the Thin-maze flat polypore (Daedaleopsis confragosa). The photo does actually show pores but they’re elongated and can resemble gills. I’m sorry if my incorrect identification caused any confusion.

 13. Hobblebush buds 

In my last post I talked about bud how scales enclose and protect buds throughout winter. Not all plants use bud scales for protection though; some like the hobblebush in this photo have naked buds.  Instead of using bud scales plants with naked buds often use fine hairs like those that can be seen on the fuzzy leaves and stems of the hobblebush. If there isn’t a flower bud between them the tiny naked leaves almost look like hands clasped in prayer. I like to imagine that they’re praying for spring like the rest of us, but I don’t know for sure.

 1. Keene State Plaque

Recently a little birdie told me that some of the students in a certain biology class at a certain college were saying that it was “too cold” and that they “couldn’t walk in the snow.” And how were they supposed to find anything anyway when there’s “snow everywhere?”

Just for fun I decided to return to college myself just to see how valid these complaints were.

 2. Keene State Parker Hall

This was my chosen starting point on the campus of Keene State College. The great thing about nature study is it doesn’t matter which path you take. Nature will have something interesting to show you no matter where you go. With a willingness to participate and a little extra attentiveness you will learn things that you’ve never even imagined.

Oh-you will notice that the snow isn’t “everywhere.”

 3. Boston Ivy Berries

My first stop was the ivy covered walls of Parker Hall shown in the above photo. This photo is of Boston ivy (Parthenocissus tricuspidata), which lends its name to the “ivy league” schools. The odd thing about Boston ivy is its name, because it isn’t from Boston and it isn’t an ivy; it’s a member of the grape family and comes from China and Japan. This vine attaches to just about any vertical surface with tiny circular pads that form at the ends of its tendrils.  It secretes calcium carbonate and uses it to “glue” the pads to the surface it wants to climb. The glue can to hold up to 260 times its own weight.

4. Crabapples

If you are a biology student reading this blog then this photo should have you asking questions like why haven’t the birds eaten these crabapples?  You can see the hundreds of them in the background on the snow even though many birds, including robins and cedar waxwings, love crabapples. In a winter as harsh as this one you would think they would be gobbling them as fast as they could, so why aren’t they? Science has shown that birds will leave fruits that are lower in fat for last but are crabapples low in fat? The answers are simple; many crab apples are ornamental cultivars that birds just don’t like. Some other cultivars have fruit that birds will eat only after it has frozen and thawed several times.  If you want to attract fruit eating birds with crab apples (Malus) the choice of cultivar requires some research.

 5. Lilac Buds 

One of the ways to identify trees and shrubs in winter is by their buds. The size and placement of buds as well as the number of bud scales can all help with identification. Bud scales are modified leaves that cover and protect the bud through winter. Some buds can have several, some have two, some just one scale called a cap, and some buds have none at all. Buds that have several scales are called imbricate and have scales that overlap like shingles. The lilac buds in the above photo are good examples of imbricate buds.

 6. Cornelian Cherry  Bud  aka Cornus mas

Buds with just two (sometimes three) scales are called valvate. The scales meet but do not overlap. This Cornelian cherry bud is a great example of a valvate bud. In the spring when the plant begins to take up water through its roots the buds swell and the scales part to let the bud grow. Some bud scales are hairy and some covered with sticky resin that further protects the bud.

Cornelian cherry (Cornus mas) is an ornamental flowering shrub related to dogwoods. It blooms in early spring (in March) with clusters of blossoms that have small, bright yellow bracts.

 7.  Powdery Goldspeck Lichen aka Candelariella efflorescens 

Powdery goldspeck lichens ( Candelariella efflorescens) grow on tree bark of all kinds. The round, flattened, yellow patches are very small but grow in large colonies that make them easier to see.  Winter is the perfect time to look for lichens because they aren’t hidden by foliage. I saw plenty on this campus.

Lichens are great indicators of air quality because they refuse to grow where the air is polluted. There was a famous study done by schoolchildren in the United Kingdom in the 1960s. They produced a “mucky air map” that showed the absence of lichens from areas polluted by coal burning. Such a study (on a much smaller scale) done on a college campus might be a real eye opener. The lichens wouldn’t even have to be identified; simply recording their presence is enough. The absence of lichens is not a good thing.

 8. Lenticels in Bark

The Tibetan cherry (Prunus serrula Tibetica) is also called the paper bark cherry because of the way its bark peels as it ages, much like a birch. It is used as an ornamental tree as much for its bark as for its flowers. The mahogany bark has very long, closely spaced lenticels that give it an unusual appearance. Lenticels are corky pores that allow gases like oxygen to reach the living cells of the bark. Without enough oxygen, bark can die.

9. Sweet Gum Pod

I was surprised when I finally realized that these were sweet gum seed pods, because Massachusetts is the northernmost point that sweet gum grows naturally in the U.S. and, though it is native to the east coast, it is considered a “southern tree.” But, there is an old (often risky) trick that landscape designers will sometimes use if a client is determined to have a certain plant that isn’t hardy-they use masonry. If a plant that isn’t reliably hardy is planted near masonry it will often survive lower temperatures than it would otherwise because the masonry absorbs heat from the sun during the day and releases it slowly at night, keeping the plant warm enough to survive. There were several of these sweet gum trees near a massive wall of brick, and they were protected from wind by other buildings.

10. Sycamore Fruit

I’ve never heard of a dwarf sycamore tree but this is an empty sycamore seed head that I plucked from a tree with very mottled sycamore bark that stood no more than 7 feet tall. There are a large number of ornamental trees on this campus and I’m not sure how I would identify them all without occasionally asking the head gardener.

 11. White Rot Fungus aka Fomitiporia punctata

White rot fungus (Fomitiporia punctata) covered this fallen oak limb. There are many species of white rot fungi and they play a major part in wood decomposition. Scientists have discovered that they will also biodegrade environmental pollutants and certain chemical wastes. Researching that might be very interesting.

 12. Amber jelly Fungus

Amber jelly fungi (Exidia recisa) were on the same fallen oak limb, but frozen solid by the looks. This is the first time I’ve seen these growing on oak. I usually find them on alder. Some jelly fungi are also good at helping wood rot. This one fruits in late fall and winter and is a true winter fungus. I’ve always wondered why certain fungi only fruit in winter.

13. Barberry Berries

I was surprised to see this very invasive Japanese barberry (Berberis thunbergii ) growing as a hedge but as I think about it I shouldn’t have been. I’ve planted barberry hedges myself back when we didn’t realize how invasive it was.  I also saw burning bushes used in a hedge. Also called winged euonymus (Euonymus alatus), they are also very invasive and until recently were widely used. The final invasive that I found was oriental bittersweet (Celastrus orbiculatus). These were growing near a chain like fence-right where a bird might sit for a while after eating its berries.

Exploring their campus for invasive species would be a good project for a biology class and could be done at any time of year. The results might be surprising for those in charge of such things since, in this instance, this is a state college and the state has banned selling or importing these invasives.

 14. Daffodils 

The most satisfying thing I found on this campus was the little taste of spring provided by these inch high daffodil shoots. I was surprised since we had just seen a temperature of 7 below zero the night before.

So, if anyone reading this happens to be a student attending a certain biology class in a certain college, this post is for you. All of these photos and at least twice as many more were taken in less than an hour while meandering around the Keene State College campus and I didn’t once have to step in snow deeper than the soles of my hiking boots. It was cold but I dressed for it. That’s what we have to do to keep warm in a New England winter.  I hope this post has shown how easy it is to find things in nature with very little effort.
