Um … anyone else having trouble uploading/editing multiple-picture-posts? Is this a my dumb internet thing? Or a new post-version thing? Ugh, annoying. I will try not to let it get me down and color my opinion of today’s lichen, M. polyphaea. This crustose lichen has a thin, wrinkled, gray-green thallus with black-disked apothecia. The surface is often coated in a thin layer of powdery pruina. M. polyphaea grows closely attached to smooth tree bark in the SW U.S. Pretty sure. There are records of it growing elsewhere, but the description I am reading is pretty specific about that range. IDK, a lot of things aren’t making sense to me today. But you know what does make sense? Falling in love with little dudes like this.
It was a long day and a late night, so in lieu of a typical post, please enjoy some pictures of my #1 lichen inspector, Boötes, giving a Hypogymnia lichen the smell test
I have been really thinking I need a haircut lately. I can’t pull off the long-haired, brunette look like N. abbreviata. This brittle, fruticose lichen grows on conifers in chaparral and coast-adjacent woodland. It has a reddish-brown, fruticose thallus, and flat, concolorous apothecia surrounded in a ciliate margin. Nododobryoria was only recognized as a sperate genus from Bryoria lichens in 1995 due to a difference in chemical composition and cellular structure. Goes to show you shouldn’t judge a lichen by its thallus–it’s what’s on the inside that counts!
ok, before I get a bunch of messages and reblogs like “Oh! I’ve seen this! It’s all over my neighborhood!” I am gonna kill your hopes and dreams right now by saying what you are most likely seeing is Xanthoria parietina, which is super common pretty much everywhere and grows on just about everything. But, if your neighborhood happens to be a wind-swept, rocky, coastal habitat in Europe or northern Africa, this might actually be your guy! X. aureola is has a thick, golden-yellow to orange, foliose thallus made up of narrow, strap-shaped, overlapping lobes. It rarely produces apothecia, which are flat, round, and concolorous with the upper surface. It grows on nutrient-rich or siliceous rocks and cliffs along the seashore, and occasionally on walls and old wood.
Can you believe people have the gall to describe P. herrei as “ragged?” When it is probably the most stunning thing I have seen today? The nerve, honestly. This foliose lichen has long, thin lobes that grow straight-up or drooping over. The lobe edges are covered in a thick layer of isidia (clonal propagules containing both algal and fungal components). The upper surface is typically a pale gray or green, sometimes turning brown after prolonged sun exposure. The lower surface is patchy white, gray, and brown with few rhizines. P. herrei grows on conifers in the Pacific NW of North America. And is beautiful and perfect and not ragged even a little bit.
Venerating celebrities is out, venerating lichens is IN! Public figures will let you down and devastate you emotionally but you know who would never do that to you? D. venustum. They’re your unproblematic fave now. Deal with it.
This crustose lichen grows in thick, white rosettes dotted with black or chalky gray apothecia. It colonizes calcium-rich rocks and human-made surfaces in open areas of northern Africa, Asia, Europe, North America, and Greenland.
Dark lichens are easily overlooked compared to their flashier cousins, but when you get up close and personal, you can see how stunning they truly are! This strongly lobed, foliose lichen grows in rounded rosettes closely attached to vertical, siliceous rock. It has a dark olive to brown to black upper surface, and a dark, rhizinate lower surface. It produces dark brown to black soredia, and only rarely, sorediate-encircled apothecia. M. disjuncta grows in boreal and montane habitats in North America, Europe, northern Asia, and central Africa.
Can you believe this little little gray spot is a lichen? It’s true. A. trolocularis is a foliicolous lichen, meaning it grows on the surface of long-lasting leaves.
A little inside peak into Lichenaday HQ–when I search for images of a lichen, a lot of times I get pictures like this:
This is a picture from a botanical collection (The New York Botanical Garden in this one) of a lichen specimen. And a lot of times, these pictures are not that great. Like in this picture, it is hard to know what you are supposed to be looking at because there’s a big, dry, dead leaf with a bunch of splotches on it. And believe it or not, this is one of the better ones I’ve seen! Because A. trilocularis, the subject hear, is kinda just a splotch on a leaf, and this was the only picture of it I could find that actually like, shows *the leaf.* For a lot of other lichens, once they are dried and aged, they don’t look like the living specimen at all, and the pictures are often from such a distance that you can’t tell what the F you are looking at. But those are the only pictures I find for lots of species. I avoid posting them because they are usually not great to look at and not super helpful for field ID purposes, but I thought I’d share this one so you get an idea of the substrate for this little splotchy fella.
Naming a kid anytime soon? Have you considered the name Coralliza? And they can go by Liza, and people will be like, “oh, like Liza Minnelli?” and they can be like “No, like the lichen.” This crustose lichen is described as coralloid, or coral-like in growth form. It grows in 2 mm thick patches of cracked, grainy, bright yellow thallus. It has flat-disked, yellow apothecia, often with a gray or black tint. C. coralliza is ornithocoprophilic, meaning it likes to grow where there is lots of bird poop! So you can often find it near coasts or high in the mountains, growing on rocks and roofs frequented by perching birds. Maybe not what you want to name your kid after, but maybe it would be a reminder that even beautiful things can some out of shitty situations.
I’ll be honest with you–not a big fan of April Fool’s day. Maybe because I am gullible, or not clever enough to think of my own pranks. So instead, I am sharing what I *hope* is an elaborate prank lichens are pulling on us–The Timucua Heart Lichen Project.
The Timucua Heart Lichen (Cora timucua) is a species of lichen endemic to Florida and the only species in the genus Cora to have inhabited the United States. It is named after the Native American people who lived in Northeast and North Central portions of what is now Florida. While historically its range included large areas of Florida, the only areas where the lichen has been reported in the second half of the 20th century are the Ocala National Forest and the O’Leno State Park. Despite its showy appearance, the species has not been collected or observed since 1985, so it is at least critically endangered or possibly even extinct. The main goal of the proposed project is to conduct an extensive and cooperative search for the species throughout its historical range and areas where the species could potentially grow, to investigate if it still exists in the wild and if so, to propose actions for its conservation. The search will engage a diverse group of people, including scientific experts, lichen enthusiasts, land managers, and the general public. Cora timucua grew primarily on shrubs in the endangered Florida sand pine scrub ecoregion, of which only 10-15% is estimated to remain intact. Thus, the majority of the search effort will be conducted in that ecoregion.
I hope dearly that this gorgeous pal is just hiding somewhere out there, and we will find it alive and well in due time.
came to the west bend grotto because i was reading a book that reminded me of it and Ive always lived in Iowa but have never seen it before (probably because i was raised protestant). stayed for the lichens that are oblivious to any possible god and are having a GREAT time
me when some guy builds a huge bizarre catholic monument in the middle of nowhere in the deep american midwest but the associated rocks have convenient Nutrients

there are lichens growing on the bronze statues outside the city hall where I live and they clearly aren’t meant to be there but if I was a sculptor I would welcome them with open arms….maybe would even make the sculptures themselves to accommodate them….like they’re gonna be there anyway we may as well extend an invitation
hey im a couple years behind on the most cutting edge of lichen science, does anybody know if they’ve been able to create a genetically new lichen from known compatible lichen components in a lab yet or are the lads still getting away with it out there
Upon reading this post to my father who is a botanist heavily involved in lichen stuff: “Yes there have been a couple cases where the symbiote was created in a lab but it didn’t look natural. Pain in the ass to look up the paper right now though. Probably a cladonia lichen.”
“Yes there have been a couple cases where the symbiote was created in a lab but it didn’t look natural” absolutely terrifying lichen quote

ENOUGH. no more celebrities. we only post about biocrusts now.
“what’s your opinion on-” what’s your opinion on this sick complex community of algae, cyanobacteria, lichens, bryophytes, and assorted bacteria, fungi, archaea, and bacteriophages that colonize the soil surface?
