Letharia gracilis

This foliose lichen grows on wood and bark at high elevations in California and southern Oregon in the U.S. It was established as a separate species from the broader Letharia columbiana group in 2009, and can be differentiated from look-alike species based off of its distribution, as well as its thinner, droopier, less-branchy branches. There are unfortunately not many pictures available online since L. gracilis, since it is pretty rare and likes to grow in remote, montane locations--a real pity considering how gorgeous it is! So you know, get out there and take pictures of lichens!

Quick sketch of Pamela in a tree and Letharia columbiana on a ponderosa pine 😤🙌 It’d be cool to get to climb a tree like this for lichens, the ones I study are on small boulders. Letharia are this bright yellow-green color because of vulpinic acid, which we think the lichen makes to use as a sunblock. See if you can spot them in your area! You might see them spot you back, their common name is “brown-eye wolf lichen”. The “eyes” are the apothecia, they spread the spores of the fungi. You can think of apothecia basically as mushroom cap turned upside down like a bowl.

A beautiful chunk of Letharia columbiana from the Grand Tetons a couple years back. That was the coldest I have ever been while camping but it was still a glorious trip in the ol’ Astrovan. Plenty of alpine lakes and lichens to go round...the Letharia are especially fluorescent in winter next to the blinding white snow ⚡️☀️💗 #mycology #lichenology #grandtetons #letharia #mycoblonde #camping #brrr https://www.instagram.com/p/B-XQBR9J-9Q/?igshid=t6fvrff0pqoy
