Meanwhile - MOSS and LICHENS
It's been warmer and very rainy the past few days, so the Starry Bristle Moss (orthotrichum stellatum) near where I get the bus in the morning is all out and plumped up. Back in 2019 I posted some pics along with what it looks like when it's dry out (it's not nearly as green and lush.)
I love getting to say hi to it when it's out and enjoying the damp and wet weather like this. It's so cute!
Nearby trees have a lot more lichen than moss on them. (They have SOME moss; while the trees with the large amount of moss have SOME lichens, but it seems like an either-or thing.)
Fairly sure that the light green, larger one is common greenshield lichen (Flavoparmelia caperata).
What I can't figure out yet is the very yellow-green stuff. I'm not even sure if it's a lichen, or a moss. Or something else? In the bottom-left photo, as I zoom in, I THINK that some of the more yellow-green bits MIGHT be young versions of the grey-green greenshield lichen??? But the bottom right photo seems like a completely distinct population (on another tree).
I'm not finding anything comparable in some preliminary searches. Will keep trying, but if anyone has any clues, give me a shout!

Lichen can be a threesome between a fungus, an alga, and a cyanobacteria. The fungus is the dom
Figured you'd like to know
this is the most random info ever lmao, but y'know I love some polyarmory

Lichens are a symbiotic entity. Both fungi and algae. They come in many shapes; from leafy to whispy. Some may be mistaken for moss. You can find them on tree bark and branches, both living and dead. Their very existence is a marvel, not to mention the complex shapes they form.

Hey I’m the op from the lichen poll thingy, I really love all the wonderful tags everyone is putting in there and so curious to learn more. Didn’t know a lot about lichen before this, can only ID like 3 of them (wanted to write species but that’s not correct I assume?), so would you care to elaborate what you mean by your tags? Would love to learn!
HELL YES. I hope ur cool w/ me posting this publicly, I take any opportunity I can to gush about lichens. For reference, my tags on that poll were something along the lines of: "do YOU challenge the foundational concept of a species in western science with your existence? well you actually do but not as directly as a lichen." I'm not going to properly cite myself here because I'm lazy so take some things with a grain of salt, but BASICALLY:
- a lichen is a symbiotic relationship between a fungi (typically an ascomycete, though there are a few basidiomycete lichens) and a photosynthetic organism (usually green algae, sometimes cyanobacteria)
- the way we classify lichens, taxonomically, is based on their fungal part, also called a mycobiont. so the species name of a lichen - let's take my fruticose friend Usnea longissima for example - refers only to that fungal part.
- getting a positive species ID on that photosynthetic partner, also called a photobiont, is a lot harder, but we know that there's some overlap between the species of photobionts that different lichen employ
- so why don't we just refer to a lichen based on the mycobiont exclusively?
- because without the photobiont, the mycobiont will not grow into a lichen in any recognizable way. a lichen is NOT a lichen if it is just the fungi species it is named for, and it is not a lichen if it is just free-living algae.
- isn't it cool that some forms of life literally cannot exist as individuals? their existence is predicated on the fact that they are in partnership, inextricably linked from what our conventions of species differentiation would consider an entirely different organism. except, wait: so are we.
- human beings literally cannot function without the bacteria, fungi, and countless other microorganisms living in our intestines, on the surface of our skin, and just about everywhere else. i believe current literature states that >50% of the cells comprising the average human body are nonhuman. your microbiome is the reason you aren't just a tube that constantly leaks out partially-dissolved food matter!
- so who's to say that humans even exist as a distinct species? from a certain perspective, a human being is just an organic scaffold that houses a community of billions of individuals.
- get out there and appreciate your local lichens!!!
