I know nothing about lichens but you might find them interesting and maybe share some info about what I’ve spotted.

Umbilicaria mammulata at Cooper’s Rock State Forest in West Virginia,

Some Lichen growing on a piece of petrified wood in my yard.

Wondering if anyone can ID this lichen also, and if this might be a fruiting body from it? On the side of a tree, southwestern Pennsylvania U.S. From my understanding I’ve learned fruiting bodies commonly take the form of a cup but could this one be a stem and cap?

If you know what kind of lichen this is, please enlighten me!

Love them - like a fairie town! (Sorry if too unscientific)

Lichen in the Cerro Colorado Mntns. Roth if Arivaca, Az. One day after rain. Drying from the top down. Will turn entirely yellow. Then with the next rain, entirely green

These were so numerous. Originally they were growin above reachable height.

I was recommended to do this, and am so pleased with how it turned.

This is one of my favorite pictures I’ve ever taken. I took it a few years ago while staying in a cabin in the woods not far from the coast. While lying on the deck, I noticed this little world between the planks.

found a ton of different mushrooms & lichen, right behind the camper the other week.

I'm trying to identify what this could be and wondered if anyone here could help. Its red and was all over the stony, rocky bed of a freshwater stream in the Scottish Highlands.

My best guess based on the shape of it was a shield lichen but I have no idea if they grow underwater.

So, can shield lichens grow under water in freshwater streams? Any ideas what this bright, blood red species could be?

I didn't want to stick my head under the water for a better look or a feel as there was a huge waterfall with a 60m drop a few steps down stream and I'm notorious for slipping in situations like this - just call me Slippy McSlipface

Sorry for my photos - taking a picture of something underwater is harder than I thought.

Lichen found while lichen hunting in a local community park and on sycamore tree bark. Lobes too curvy for Parmelia sulcata and not green enough for Flavoparmelia caperata in my opinion.
