Posts Tagged ‘Hammered Shield Lichen’

Last weekend I remembered that I hadn’t climbed any hills in a while so I chose Hewe’s Hill in Swanzey. The trail starts in a meadow / hayfield and I was surprised to see a path starting to wear into the grass. I suppose it must be becoming a popular climb even though I rarely meet anyone here.

There was a nice display of big leaf asters (Eurybia macrophylla) and gray goldenrod (Solidago nemoralis) along the edge of the field. The big, hand sized, heart shaped leaves helped me identify the asters.

The trail starts out narrow and level but before long it widens and angles uphill.

A ray of sunshine had found a colony of shining clubmoss (Lycopodium lucidulum) and made it shine even more. This clubmoss is unusual and easy to identify because it is unbranched and grows fairly erect.

Cockscomb or crested coral (Clavulina cristata) grew on the side of the trail. Crested corals have branches that end in sharp tips and these tips will often turn brown, but these examples were still nice and white. It had rained all day the day before so it might have been very fresh. I’m not sure what the tiny yellow fungus in the background was.

The names pinwheel and horsehair mushroom are interchangeable and go by the scientific name of Marasmius rotula. They grow on decaying leaves and decaying wood and can appear overnight after a good rain. They are very small and rarely grow larger in diameter than a pea. This one grew on last year’s leaves and was easily the largest I’ve ever seen with a diameter equal to that of an aspirin.

Another record mushroom in my book was this hemlock varnish shelf fungus (Ganoderma tsugae.) It was larger than a dinner plate and I’d guess quite old. Its common name comes from its shiny cap which usually looks like it has been varnished, but this example was very dirty. This mushroom is considered the most important of all the herbs and substances used in Chinese Herbal Medicine, including ginseng. In China it is called the Reishi mushroom and scientists around the world are researching its anti-cancer potential.

The trail goes gently uphill until we near the summit where the grade is steep. It’s very dark through this section of forest because of the overspreading evergreen branches of pines and hemlocks.

If you look closely at the tree to the left of the trail in the previous photo you can see that it is full of woodpecker holes. This photo shows how the wind carried mushroom spores into one of those holes and they grew there, fruiting on this day or the day before. This is how fungi infect and almost always kill the trees they grow on. All it takes is a small wound, and that’s why wounds on expensive ornamental or fruit trees should be quickly treated.

When trees die they eventually fall and I saw several down across the trail. This hemlock was the largest. Note all the tree roots on the trail where the soil has washed and worn away. They can be very slippery after a rain and I slipped on them a few times on my way down the hill.

Hammered shield lichen (Parmelia sulcata) and crowded parchment fungi (Stereum complicatum) battled for space on a fallen limb. There was plenty of room for both to the right and left but crowded parchment fungi often covers entire logs, so it wants all the space.

Yellow patches (Amanita flavoconia) gets its common name from the yellow bits of the universal veil on its orange cap. The universal veil is made of tissue and completely covers the young mushroom. As the mushroom grows it eventually breaks through the membranous veil and pieces of it are left behind on the cap. Rain can wash them off so I was surprised that they have stayed in place on this example. This mushroom is in the amanita family and is considered toxic. The amanita family contains some mushrooms that can kill if eaten, so I never eat any mushroom that I’m not 110% sure is safe. In truth I’m not crazy about mushrooms anyhow so their toxicity is a non-issue for me.

Indian cucumber root (Medeola virginiana) was showing its fall colors. This plant has small black berries but this example didn’t have any. Little is known about what animals eat the berries but it is said that the Native American Iroquois tribe used the crushed dried berries and leaves to treat convulsions in infants. Native Americans also ate the roots of the plant, which taste and smell like a cucumber. I accidentally scared a turkey away and I wondered if it was that bird eating all the berries. I also saw plenty of blueberry bushes but not a single one had a berry.

This fungus grew right on the ground and looked like it was pretending to be a pizza. I haven’t been able to identify it.

I didn’t expect the views to be very good due to the previous day’s heavy rain, so I wasn’t disappointed when they weren’t. It was very hazy but you can still see the trees; countless thousands of them. I didn’t see much leaf color yet though some seemed to be lightening up to a yellow green.

Out of several shots of the views I took this is probably the best as far as lack of haze.

As I stood scanning the trees for signs of fall color a large shadow crossed over me and when I looked up I saw a flock of what I think were turkey vultures circling silently above me. They looked to be huge, and there had to have been 7 or 8 of them. Big birds flying across the skies; throwing shadows on our eyes. These words from Neil Young’s song Helpless played in my mind as I watched them soar.

These aren’t very good photos but my getting-photos-of-birds-in-flight skills are just about nonexistent. What struck me most about these birds other than their large size was how absolutely silent they were. They never made a sound the whole time I watched them; there wasn’t even the sound of wind in their feathers even though they flew so close once or twice it seemed like I could have reached out and touched them.

Because of the previous day’s rain many of the little toadskin lichens (Lasallia papulosa) that live up here were their natural green color and plump with plenty of moisture. When wet the greenish color of the algae that is present in the lichen comes through on the surface. The tiny black specks in its lower left corner are its disc shaped fruiting bodies, called apothecia, where its spores are busily being produced so a new generation of toadskins can get their start.

When wet toadskin lichens are rubbery and pliable and feel much like your ear lobe but when they dry out they are much like a potato chip, and will crack just as easily.  Like many lichens they also change color when they dry out, like the dry example in the above photo shows. The warts on its surface are called pustules and on the back of the lichen there is a corresponding pit for every pustule. Each lichen is attached to the rock at a single point that looks much like a belly button, so this is an umbilicate lichen. This example’s belly button is the bright spot that looks like a sun in a solar system.

I’ve written several posts about Tippin Rock, which is the 40 ton glacial erratic that lives up here, so I was going to just pass it by without taking a photo, but then I saw something I hadn’t seen before. At first I thought I had come upon one of those benevolent forest sprites whose job is guiding creatures who pass through the woods and protecting the forest, but instead it was Gus. “Are you tipping that rock?” I asked, and Gus giggled and said no, it was his father making it tip. Gus is a happy little guy who was overcome by bursts of great joy each time his father made Tippin Rock tip. It’s truly amazing to see 40 tons of granite rock gently back and forth like a baby cradle and Gus was having a ball riding the huge stone but truth be told, his dad was looking a little winded. From what I gathered Gus and his dad and their dog Annie had come up here specifically to tip the rock, and tip it did, again and again and again. Once I thought it might actually tip off its natural keel and never move again but Gus rode it out and everything was fine.

I don’t get many chances to show a person’s size in relation to the big boulder so I was grateful when Gus’s father graciously said that I could take a few photos. Gus is a very bright, joy filled five year old who is as cute as a button. He told me that he likes school and loves his teacher very much, and I told him that I’d bet that his teacher loved him right back. Gus also told me that he and his family were having a dinner party the following evening and said that I should come so he could show me around, but I left the family to their fun and headed off down the hill.

Anyone who reads this blog regularly knows how I harp about people getting into the woods so it was a real pleasure meeting Gus and his dad and their dog Annie up there; easily the high point of my entire weekend. I hope Gus grows up to be a great lover of nature; he’s certainly off to a great start.

Last Saturday the weather wasn’t cooperating at all. As the above radar image shows there was a thin ribbon of rain from the Midwest to the northeast. In my corner of New Hampshire it was in the mid-30s and we had snow mixed with rain, which translates into a sloppy mess. With the hill climbing trails still covered in snow and ice March continues to be a challenge.

This is what the view out my back door looked like while it snowed.

In spite of a near blinding snow squall this willow’s golden branches lit up this space. Golden willows are one of the earliest signs of spring in this area.

I’m guessing that I won’t be seeing any yellow flowers on the pussy willows (Salix) real soon. Once the snow stopped they had ice on them on this day.

A sedum decided to throw caution to the wind and come up anyway, even if it was snowing. The shoots looked like tiny cabbages.

Buds of American elm (Ulmus americana) are just starting to open. Their flowers are unusual and beautiful and I hope I don’t miss them this year. I know of only two trees with branches low enough to reach.

Last year this magnolia blossomed too early and lost nearly every flower to frost because of it, but this year there is still a single furry bud scale on every bud. They looked a little wet and bedraggled but they’re still protecting the flower buds inside. Soon they’ll fall off and the tree will start to blossom, cold weather or not.

It looked like the bud scales on these box elder buds (Acer negundo) were just starting to open. The buds and young twigs of box elders are often a beautiful blue or purple color due to their being pruinose. Pruinose means a surface is covered in white, powdery, waxy granules that reflect light in ways that often make the surface they are on appear blue. Certain grapes, plums, and blueberries are pruinose fruits. Certain lichens like the beautiful smoky eye boulder lichen have fruiting bodies (Apothecia) that are often pruinose. Box elder is in the maple family and several Native American tribes made sugar from this tree’s sap.

Lichens are at their best in wet weather so I decided to look at a few I hadn’t seen in a while. I can’t speak for the rarity of hammered shield lichen (Parmelia sulcata) but I do know that I rarely see it. This lichen gets its common name from the way it looks like its lobes were hammered out of a sheet of steel. This one grows on a tree in a local shopping mall. It’s the only example that I could confidently lead  someone to if they asked to see one.

On the same tree, just a few inches away, grows a star rosette lichen (Physcia stellaris) that produces spores quite regularly. The dark brown apothecia with white rims are fairly easy to see without magnification but there was something else here that I had never seen.

I’ve seen many lichens with apothecia that are cup shaped as this one has but some of these cups were full of water, and that’s something I’ve never seen. I don’t know how or even if this benefits the lichen but I do know that most of them like a lot of water. Star rosette lichen gets its common name from the way its lobes radiate outward like a star.

If you don’t mind getting down on your stomach in the kind of swampy ground that they like to grow in you can sometimes get a peek inside the spathe of a skunk cabbage (Symplocarpus foetidus) to see its flowers. A spathe is just a modified leaf or bract which kind of wraps around itself and protects the flower bud. As the plant matures a gap opens in the spathe to let in the insects which will pollinate the flowers. This one was open far more than they usually are and I wondered if someone had been there before me, taking a peek inside.

Inside the skunk cabbage’s spathe is the spadix, which is a one inch round, often pink or yellow stalked flower head from which the small flowers emerge. The flowers don’t have petals but do have four yellowish sepals. The male stamens grow up through the sepals and release their pollen before the female style and pistil grow out of the flower’s center to catch any pollen that visiting insects might carry from other plants. The spadix carries most of the skunk like odor at this stage of the plant’s life, and it is thought that it uses the odor to attract flies and other early spring insects. This example had released a large amount of pollen and it was stuck to the insides of the spathe. In 1749 in what was once the township of Raccoon, New Jersey they called the plant bear’s leaf because bears ate it when they came out of hibernation. Since skunk cabbage was and is the only thing green so early in the spring so if the bears woke up too early they had to eat it or go hungry.

Some of the skunk cabbages came up too early and paid for their mistake by being frozen. Now their spathes are shriveled and black. This one had a new green leaf shooting up beside it but its spathe didn’t look good. The leaf will keep the plant alive but it will have to wait until next year to blossom again. There is a time when they’re young that the leaves do look somewhat cabbage like but they grow quickly and lose any resemblance once they age.

I doubt it would help pollinate a skunk cabbage but I did see what I think is a wasp recently. It seemed sluggish; most likely because of the cold. It did finally rear up on its hind legs when I got the camera too close, but I don’t think it was in any position to sting just yet. It seemed like it could barely stand. After a couple of quick shots I left it alone to contemplate the weather.

Reticulated irises (Iris reticulata) are our earliest iris I think, and usually bloom at about the same time as the crocus does, though this year I saw a crocus blossom two weeks ago. This beautiful and tough little plant comes from Turkey, the Caucasus, Northern Iraq and Iran.

This one looked more like an iris, even with the ice on it making its petals curl. Reticulated iris are a much tougher plant than I ever realized and I appreciate them and the other early bloomers showing me that spring is indeed here, even though it still feels like winter.

The first day of spring is one thing, and the first spring day is another. The difference between them is sometimes as great as a month. ~Henry Van Dyke

1-bridge

The last time I talked to anyone at the Keene Middle School about it, it looked like the boardwalk through Tenant Swamp behind the school might be closed in winter, so I was happy and surprised to find it open last weekend. You enter the swamp by crossing this bridge.

2-stream

The bridge crosses over a small stream which on this day had a skim of ice. For a swamp there is remarkably little standing water seen here.

3-boardwalk

I was happy to see that the boardwalk had been shoveled. At least I thought so…

4-boardwalk

Until I walked a little further and saw this. The snow had turned to a solid block about 3 inches thick, but thankfully it wasn’t slippery. On the left in this photo you can see the tall stems of the common reed, which is invasive.

5-phragmites

The invasive reed is called Phragmities australis and has invaded the swamp in several places. Even in winter its reedy stems block the view. Tenant swamp is bisected by a highway (Rte. 12 N.) and you can see large colonies of it from the road. This reed came from Europe and forms large monocultures that even burning can’t control unless it is done 2 or 3 times. Not only does a thick matted root system choke out other plants, but decaying reeds also release gallic acid, which ultraviolet light turns into mesoxalic acid and which means that seedlings of other plants that try to grow near the reed have very little hope of survival. It appears to be here to stay.

6-swamp

I think that even if I was blindfolded and brought here I’d know that I was in a swamp. There just isn’t anything else quite like them and being able to walk through one is a rare opportunity. In 2010 Keene built a new middle school at the edge of Tenant Swamp and the building sits on a high terrace that overlooks it. Before the school could be built however an archaeological sensitivity assessment had to be done, and by the time the dig was completed it was found that Native Americans lived here at the end of the last ice age, approximately 11,000-12,000 years ago. The dig also found that the Ashuelot River once ran through here; about a half mile east of where it now flows. Since the site evolved into a swamp it was never farmed or built on so it was valuable enough archeologically to be placed on the National Register of Historic Places.

Since then, after much hard work and fund raising, a path and boardwalk leading into the swamp itself was built. It’s the kind of place that people rarely get to experience so it is meant to be a kind of outdoor classroom for anyone who wants to learn more about nature.

7-spruce

One of the most notable things seen here are the many spruce trees, because they aren’t normally plentiful in this area. It must stay relatively cool here because spruce trees prefer the boreal forests further north. There are at least two species here and I think they were probably red spruce (Picea rubens) and black spruce (Picea mariana.) Neither one minds boggy ground.

8-spuce-trees

Many of the older spruce trees are dying but they are pole size and I wouldn’t think that they’d be too old. I can’t even guess what would be killing them.

9-spruce-bark

Something had peeled the outer bark off this spruce to expose its beautiful, colorful inner bark.

10-beard-lichen

The spruce trees are hung thickly with beard lichens (Usnea) in places. These lichens seem to especially like growing on the bare branches of evergreens. I’ve met people who think the lichens kill the tree’s branches but they don’t, they just like plenty of sunlight and bare branches get more of it.

11-winterberries

Winterberries (Ilex verticillata) are a native holly that love wet feet so I wasn’t surprised to see many examples of them here. The berries were a little puckered but birds are probably still eating them because I rarely see any in the spring.  Robins, catbirds, mockingbirds, Eastern bluebirds, and cedar waxwings all eat them.

12-winterberries

The bright red color of winterberries makes them easy to see. There are also many blueberry bushes growing here, but I didn’t see a single berry on them. When I thought about it I realized that this swamp is full of food for birds and animals, and for humans as well.

13-cattail

Cattails (Typha latifolia) were an important food for Native Americans. Their roots contain more starch than potatoes and more protein than rice, and native peoples made flour from them.  They also ate the new shoots in spring, which must have been especially welcome after a long winter of eating dried foods. Some of the cattails were releasing their seeds, just in time for the return of red winged blackbirds. The females use their fluffy fibers to line their nests. Cattails can grow faster than fertilized corn and can create monocultures by shading out other plants with their dense foliage and debris from old growth. They are very beneficial to many animals and birds and even the ponds and lakes they grow in by filtering runoff water and helping reduce the amount of silt and nutrients that flow into them.

14-bobcat-tracks

I saw what I think were bobcat tracks meandering around and under the boardwalk. There are many squirrels in this swamp and it might have been hunting.

15-hole-in-tree

This might have been a squirrel’s home, but it was too high up to look into. It might also have been an owl’s home, so it was probably best that I didn’t stick my nose into it.

16-alder-cones

Alders (Alnus) love to grow near water and they are one of the easiest shrubs to identify in winter. This is because the alders, of which there are about 15 species native to the U.S., bear seed pods that resemble miniature pine cones.  These cone shaped seed pods are the fruit of the female flowers and are called strobiles. Many birds eat alder seeds including ducks, grouse, widgeons, kinglets, vireos, warblers, goldfinches and chickadees. Moose and rabbits feed on alder and beavers eat the bark and use the stems to build with. Native Americans used alder as an anti-inflammatory and to help heal wounds. They also made a tea from it that helped cure toothaches. Those allergic to aspirin should not use alder medicinally because the bark contains salicin, which is similar to a compound d found in aspirin.

17-fern

There are many ferns here. When I visited the swamp in the summer I saw some that were easily waist high; mostly cinnamon ferns (Osmundastrum cinnamomeum,) which love boggy ground. Of course you won’t see any in winter but you can see plenty of signs that they grow here.

18-blue-pine-sap

I’ve seen lots of pine (Pinus strobus) sap turn blue in winter cold but this is the deepest blue that I’ve ever seen it. That’s odd since it really hasn’t been that cold since December. Native Americans used pine sap (or pitch) to treat coughs and pneumonia. It was also used to treat boils, abscesses and wounds.

19-lichen-on-moss

Lichens like plenty of water and mosses soak it up like little sponges, so this friendship between a crispy tuft moss (Ulota crispa) and a hammered shield lichen (Parmelia sulcata) is no real surprise. Hammered shield lichen gets its common name from the netted surface of each of its many lobes. It is also called the wax paper lichen, and if you’ve ever crumpled a piece of wax paper and then flattened it again out you know just what this lichen looks like.

20-swamp

To a nature nut the swamp is like a siren’s call and I would have loved to step off that boardwalk and explore it further, but then I remembered the stories of people getting lost there. A five hundred acre swamp is huge and I’m guessing that I’d probably be lost in under an hour. In November of 1890 George McCurdy went in and never came out alive; he died of exposure. They found him, but I’ve heard stories about another man who went into the swamp and was never found.  As much as I’d love to explore more I think I’ll just stay on the boardwalk for now.

The most primitive places left with us are the swamps, where the spruce still grows shaggy with Usnea (lichen). ~Henry David Thoreau

1. The Tree

A few posts ago Jerry from the Quiet Solo Pursuits blog and I were talking about how much there is to see on the bark of trees. Almost like an entire world in one square foot of tree bark, we agreed. Of course that got me thinking that it might be interesting to see what I could actually find on a square foot of tree bark, and the above photo is of the tree I chose. It’s nothing special; just a tree in a local shopping mall, but I’ve had trouble figuring out what it is. Landscape architects have hundreds if not thousands of trees to choose from these days, so it could be from virtually any place on earth. Its bark and shape look a lot like hop hornbeam, but I don’t think that’s what it is. Anyhow, this post isn’t about the tree.

2. Miniature Garden

This post is about the gardens that grow on trees, and this particular specimen had so much growing on it that you could hardly see its bark in places. To give you some idea of the scale of what we’re looking at, that little tuft of moss in the center of the photo is roughly the same diameter as a quarter, or slightly less than an inch (24.26 mm).

At this point I should say that, though many people think that lichens, mosses, and algae growing on a tree will harm the tree, that isn’t true. These growths are epiphytes and take nothing at all from the tree. They are simply looking for a convenient place to perch, much like a bird, and get everything they need from the sun, rain and air. However they do like high humidity and still air and their presence might be a sign that the tree should be in a drier place with better air circulation, but if a tree seems sick we shouldn’t automatically blame what’s growing on it. Instead we should call a certified arborist and find the true cause.

3. Moss

Trees have natural channels in their bark that channel rain water down to their roots, and mosses and lichens often take advantage of that. Both lichens and mosses like lots of water and can usually be found growing along these tiny streams. This photo is a closer look at the moss in the center of the above photo. I’m fairly certain that it’s called Lyell´s bristle-moss (Orthotrichum lyellii.) In this photo it was good and wet.

 4. Moss

It’s hard to believe that this is the same moss that’s in the previous photo, but it is. The difference is this photo shows what it looks like when it dries out. I took these photos over a few days so I could show you the changes that these plants go through between their wet and dry states. This is a good illustration of why serious moss and lichen hunters do so immediately after it rains.

5. Penny on Tree

I finally figured out how to make a penny defy gravity so we could get an even better idea of the scale of some of these lichens. For those of you not familiar with the size of a penny, they are 3/4 of an inch (19.05mm) in diameter. Unfortunately, though I can show you this lichen’s size I can’t tell you its name. There are a few poplar sunburst lichens in this area but I’ve never seen one as flat or as round as this one, so I’m not sure if that is what it is.

6. Unknown Yellow Shield Lichen

Whatever it is it was producing spores, as its tiny round fruiting bodies (apothecia) show. They’re the parts that look like tiny suction cups. For now I think I’ll just call it a yellow shield lichen. I know where it lives so I’ll watch it over time to see how it changes.

7. Poplar Sunburst Lichen

I have no doubt that this lichen is a poplar sunburst lichen (Xanthoria hasseana.) Its growth habit is much different than the flat, round example seen previously. Virtually every photo I’ve seen of this lichen shows the mounded, irregular shape seen here.

8. Poplar Sunburst Lichen

Poplar sunburst is a beautiful lichen and one of my favorites. It seems to never stop producing spores as the many fruiting bodies (apothecia) in this photo shows. You would think that such a prolific lichen would show up just about everywhere, but this is the only place I’ve ever seen it. That makes me wonder about the viability of its spores and how far they really travel on the wind.

9. Star Rosette Lichen

This lichen almost had me fooled into thinking that it was a black eyed rosette lichen (Physcia phaea) but the photo clearly shows that its “eyes” (apothecia) are more bluish gray than black. For that reason I believe that it’s a star rosette lichen (Physcia stellaris), which has dark brown apothecia that are often pruinose. Pruinose refers to a white, waxy, powdery coating like that found on blueberries, plums, and first year black raspberry canes. I’ve noticed by watching smoky eye boulder lichens, which also have pruinose apothecia, that the coating can reflect light in different ways, sometimes appearing gray and at other times more blue.

10. Powder Edged Ruffle Lichen aka Parmotrema stuppem

The uniform pale gray color, broad rounded lobes with erect edges, and soralia on the lobe edges all point towards this being a powder edged ruffle lichen (Parmotrema stuppeum). In this example the soralia are white and granular and make the lichen look like its edges have been dipped in sugar.  Soralia are meant to fall or break off a lichen and are used as a vegetative means of propagation. Another feature used to identify this lichen is its black to brown undersides, which aren’t visible in this photo.

11. Rimelia Reticulata Lichen

Here is another example of soralia (aka soredia) on the lobe edges of a lichen but these are much larger and more noticeable than those in the previous photo, and it’s easier to imagine them breaking off when a chipmunk runs over them. I’m fairly certain that this is a netted rimelia lichen (Rimelia reticulata) because of its soralia, but also its black undersides and root like rhizines, which are hard to see in this photo but are there. This is the first time I’ve ever seen this lichen and the previous powder edged ruffle lichen, so I’ve learned a lot from that tree.

12. Hammered Shield Lichen

This lichen I have seen before but only once or twice. Because it looks like its lobes were hammered out of a sheet of steel it has the not so surprising name of hammered shield lichen (Parmelia sulcata). I’m glad that I found so many different gray lichens. At a glance it’s easy to think ho hum, another gray shield lichen, but I hope this post might convince people that it really is worth taking a moment to get a closer look. Even gray lichens can be surprisingly beautiful.

 13. Unknown

Here is something that has had jerry and I scratching our heads and wondering about for over a month now. Jerry first noticed that his lichen photos showed some kind of white, thread like filaments on them and when I went back and looked at my photos I saw that some of the lichens showed the same thing. The fact that they were on moss in this instance almost fooled me, because the club shaped objects in the photo look much like the spore capsules on a moss called puckered tuft moss (Ulota coarctata) and for a short time I thought I had solved the puzzle.

14. Unknown Seed

This photo shows a single tiny club shaped object from the mass in the previous photo. It is so small that I can’t even think of anything to compare it to. Human hair might be best, but the club like end has a greater diameter. It can’t be a moss spore capsule because if it were there would be an opening in the end nearest us for the spores to escape through. Since there is no opening it must be something else. I think that the shiny, hair-like filaments at the far end show that it is a seed of some kind, and those shiny filaments are the seed’s crushed “parachute.” It’s very similar to a dandelion seed but I don’t know if that’s exactly it. There are many other plants with cottony seeds in the area including willows, asters, cattails, milkweed, yellow goat’s beard and others, but none of them are an exact match. If you are reading this and know what plant it came from I’d be very grateful if you filled me in. I’m sure that Jerry would thank you too.

15. 800px-Dandelion_seed_-_May_2012

This excellent photo by Wolfgang Arnold on Wikipedia Commons shows the “parachute” part of a dandelion seed looking like we would expect it to, but what would it look like after being stuck to a tree all winter?  And what happens when the brown seed falls off or degrades? Does it leave a white, club shaped end like we see in the previous photo? As often happens nature brings more questions than answers, but we can learn a lot by solving the riddles that are presented to us. I’m anxious to see dandelions bloom again.

 16. Bristly Beard Lichen aka Usnea hirta

There were some very healthy looking examples of bristly beard lichens (Usnea hirta) on this tree, and If you look closely at the lower right side of this one you’ll see how the white filaments catch on lichens and show up so clearly in photos.

I’m sorry that this post turned out to be so long but that’s what happens sometimes when you stop to look at a tree-whole new worlds open up unexpectedly and you see things that you’ve never seen before. I hope you’ll find that out for yourself one day soon.

Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve. ~Max Planck
