Bushy beard lichen 》 Usnea strigosa

Some lovely beard lichens I found at our campsite.

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.

I am in a drifting phase for sure. Trying a lot of things as usual, but still not to a degree that I am satisfied with. Only way is to keep doing.

This one is about awakening from sleep or from scrolling on my phone (these are similar but non the same). I find that the stillness I feel when waking up is heavy lately. I think some of the new things I am trying will help with this, this is to be seen.

Any of yall even feel like the more aware you become of your own reality, the more your point of view is coming from somewhere else? I've felt out of body before but this is different.

Reindeer Lichen (Cladonia rangiferina)

Family: Cladonia Lichen Family (Cladoniaceae)

IUCN Conservation Status: Unassessed

Like all lichens each “individual” reindeer lichen is actually a colonial organism formed from members of at least two separate species; the main body of the lichen, the mycobiont, is a tough branching fungus that gives the lichen shape and stability, while the lichen’s greenish-blue colour come from colonies of one or more species of algae or bacteria which live on the mycobiont and produce nutrients through photosynthesis, transferring some of these nutrients to the fungus to sustain the whole colony. Found mainly on the ground in open habitats in and around the arctic circle, Reindeer Lichens are slow-growing but extremely hardy and able to remain active in much colder and darker conditions than many plants with which they coexist. This element of their biology makes them extremely ecologically important; many Arctic herbivores rely heavily or even exclusively on members of this species for food during the winter when many plants are dormant, and certain birds and small mammals may also use their branches to build or line their nests.

tfw every specimen you thought was Caloplaca saxicola is just Rusavskia elegans.

(hi I'm alive and I did get into grad school which is why I've been neglecting this blog and will probably continue to do so. but please enjoy this image it took forever to make lmao)

Toniniopsis aromatica (syn. Toninia aromatica)

Fun fact that I found about this lichen on a sketchy FB post that may be fake since I cannot find a source for this info: Despite what the name T. aromatica might lead you to believe, it doesn't have a noticeable smell, but got it's name because it was sent to the dude who described it, Sir James Edward Smith, in a perfumed envelope. It's just stupid enough that I want to believe it. This squamulose (scale-like) lichen grows on soil, rock, brick, and shingles, often associated with/parasitizing other lichens. In humid environments, it has green, white-flecked squamules and swollen, black apothecia, but in drier environments, it has gray squamules and shriveled, pruinose apothecia. T. aromatica has a couple of look-alike species including T. verrucarioides, T. mesoidea, and T. fusispora , because lichens like to make my life difficult. Makes me wish it did have a distinct smell . . .

Went lichen hunting the other day :)

I really need to have a go at it with a proper macro lens, but I also don't have anything with enough magnification that would beat me just taking a photo through my pocket microscope (the round ones, it x30 magnification)

Haven't gotten around to ID them yet

Happy Friday the 13th, everyone. 🖤

When I lead guided nature tours, I often have people asking me if the lichens we see are harming the trees they grow on. So I decided to make a little video about it!

Frosty saucer 》 Ochrolechia africana

One of the most beautiful lichens I've found recently. I love the texture the apothecia create when they cluster together like this. What I wouldn't give to be small enough to wander this structure like a field.

The one in the fourth image is possibly a different species.
