Lichen History Revised
As in any well done science work, new information that can be verified may change our understanding of the world. We can only learn ‘the next step’, we can never completely know the depth and complexity of the world from any one perspective. And so now lichenologists have found something new going on in lichens that revised our understanding of when lichens first appeared on earth as well as what makes a lichen; at least certain lichens. I suspect they will always fool us; they are too complex to box into a category and leave them there.
The study originally looked for reasons some fungi and algae ‘hug’ each other and don’t let go. But along the way, the evidence seemed to show that fungi figured out how to do this in many places and times, not just from one ancestor. The earliest fungi to do this, that humans have evidence of so far, do not show up before ferns and a few other plants. So it may be that lichen did not colonize land before plants.
There may still be more surprises in the fossil records, and we may need to revise this story again in the future. It’s like a big puzzle; each piece is useful but only part of the picture. Even though we don’t have the whole puzzle figured out, we do see part of the story. Making adjustments, like sorting pieces-sky pieces we know go near the top of the puzzle, water pieces near the bottom- helps understand the patterns of life on earth even as we continue to search for the details.
For a life as simple looking as lichen are (to us), they do have amazing abilities to be flexible and adaptable; traits we might find useful. So the scientists continue to look for why and how the lichen do what they do, and I’ll let you know when I find out too!

Veering off topic from Lichens to Mushrooms today; I just can’t help myself because the story is so wonderful. A human has written music from mushrooms. Not one song, but thousands, from every mushroom he encountered over decades of walking in the forest.
Recently a friend gave me information about the discovery that lichens disable prions, particularly the ones that make CWD. In the last post, I mused about what else they might be up to that we have no ideas about yet. As elders and others from cultures with intact connections to the living world know and occasionally inform us, everything is alive and interacts in myriad ways with the world. Some people still know that, and sometimes they make something beautiful from their love of the world’s beauty. And sometimes, a human interacts with the living world in a new and beautiful way. That’s the story of Vaclav Halek.
Today, while listening to the radio program ‘To The Best Of Our Knowledge’ the story of Vaclav Halek’s willingness to listen to what he heard years ago, and his inspiration to add his own gifts to the mushrooms’ songs so other humans could also hear them sing, brought to mind all the discoveries made about mycelium, lichens, fungi, and other Tiny Ones, such as bacteria. So few humans notice the Tiny Ones, the Small Ones, the Stemmed Ones….all those who are quiet and small and everywhere. Sometimes we “hear symphonies” when in the presence of a grand landscape, or spectacular sky. But Mr. Halek’s symphony came from….mushrooms.
While wandering in the forest in the 1980’s, he first heard music coming from a mushroom. He seemed to have no hesitation in hurrying to write down what he heard. That response started a long relationship with thousands of mushrooms, all of them giving him their own unique music. Melodies, symphonies and many other pieces of music have been created over the years.
Here is the story about Mr. Halek:
John Cage was a mycologist as well as a musician, and used mushroom names in his works. He also commented that he could hear mushrooms. So Mr. Halek isn’t the only person to be aware of Mushroom’s voice.
Here is the last stanza from his poem ‘Mushrooms’:
they’ll be separated froM the rest of creation
and pUt in a kingdom
all of tHis is an attempt
Our understanding of these plants, which perhaps
are not plants at all. so far they’ve
Managed to remain
juSt as mysterious as they ever were.
It’s easy to find a label…’synaesthesia’ and dismiss this man’s work as a harmless pathology. I invite you to consider if there are other possibilities that hold potential, or simply cause happiness, for what he is doing.
If any of us go outside our walls, away from our electronics, and become quiet and slow and wait for a while, anyone may hear or see new and wonderful ways the world is alive, and maybe even singing to us, and maybe even has something to say or offer that is worth the effort to listen.
How do you see, or hear, or smell the world? What places or beings could you discover by bringing your special awareness to a part of the world so far unnoticed? Maybe simply being in the presence of a sunset, or a mushroom, or an animal inspires your own creative expression of beauty, and maybe what is around you will also contribute in some way to that creative process. There are so many reasons to go out wandering in the fields and woods, but this is one of the most unique. If you hear a mushroom (or maybe even a lichen), let us know. And if you’re inspired by whatever you find or meet in your wanderings, please share your story.
Winter Lichens 3
Julie, Olga and I went out to view the white and wonderful woods after the big snow a couple days ago, and I, of course, had a secret agenda to also check on the Little Ones. As soon as the new snow warmed slightly the snow fleas were out hopping around. I knew the lichen would not be hopping around! But they do show their colors in the snow and I am still searching for new species. Each day in the forest brings the possibility of meeting a new lichen (as well as whatever other wonders appear whenever one stays in the woods a while). We are walking on Cutoff Trail. The ice has formed curtains along the rock walls, as it has almost everywhere this year.
No ice caves here, just a small cliff. The rock is mostly covered with liverwort, moss, fern; the lichen are small. One of my favorite trees, the river birch with its beautiful coppery bark, stands here.
The lichen like this tree too; the moist base has a colony of aqua blue lichen. Aren’t they beautiful on the red and silver bark? Since the names are not verified yet, I can describe them any way I wish, in this blog anyway! Don’t worry, names will be forthcoming by spring.
Turkeys flapped around in the treetops. The sun came out. On the south slope, snow in the branches began to melt, just enough to form liquid water at the edges of the snow on each branch. The trees were suddenly illuminated in diamonds of light. A few moments later as we walked away from the direct sunshine, the warming air simply made the clumps of snow in the branches fall off on our heads.
This is not a lichen, it is a fungus, making a little snow sculpture on the side of a tree.
While we move about so quickly and ceaselessly, the trees, moss, rocks and lichen quietly remain. The ice moves too. More slowly than us but faster than lichen, rock or tree; changing all those slow moving ones as it forms, grows and then disappears. The lichen and their rocks and trees will be here as we and the ice come and go.
Remember to enjoy the small things in life.
Winter Lichens Part 2
Remember this, from a week ago? A little frosty but still green and growing.
Today, January 10th, it was 5 degrees above zero and this is my lichen hunting outfit; every layer of Canadian ski clothes I can find:
And here’s Lichen Land now:
But as we know, the lichen are quietly waiting for the ice to melt. Meanwhile the ice is busy make beautiful patterns. I wonder what it looks like from underneath, where the lichens are?
Since it was so cold today, I went out to see what the lichens looked like on the hill behind our house. As I searched for them in the ice and snow I thought about how quickly they exchange their active life for dormancy. Another warm day and these ice covered lichen will be back to life in a few hours.
Below: very cold lichen
It’s fun to see what else is out in the woods besides the lichen.
This is the hilltop where these pictures were taken:
It’s a busy place. See all the tracks? Our coyote friends like to gather in this area and sing to us. Their tracks tell the story of what they do while here.

At the top of the ridge a dead tree trunk supported these fungus
After an hour there seemed to be more and more snow and less lichens, and it was getting colder so I went home. I went less than a quarter mile from the house and had a good adventure. What’s close to home where you live? If you’re out there and meet your own resident lichens, share them with us!
