Close-up of a fallen tree branch covered in gray and white crustose lichens, with a dense cluster of bright orange, disk-like lichens standing out near the center.

Very close-up look at dark gray lichen apothecia ringed with very light gray edges.

Orange apothecia of a lichen ringed with yellow edges.

Xanthomendoza sp. (orange) and a Physcia sp. lichens on a stick that came down with a treefall. Always cool to see what was growing way up there where only birds get to see. Two close-ups taken with DinoLite scope. #lichens #dinolite #lichen

Porpidia tuberculosa (top) and Myriospora smaragdula (bottom) on siliceous boulders in Hyde Park/Kensington Gardens, London. Common #lichens, but first park records, and indeed first record of M smaragdula for VC21 Middlesex. Found as part of my lichen walks there: exciting for public participants!

Photo taken April 28, 2019, looking up through a heavy canopy of lichen covered fir boughs near South Dubakella Mountain, #TrinityCounty, #NorthernCalifornia. It is almost so dark you need a flashlight to see, then when you get into an opening, it gets so bright. #trees #photography #nature #lichens

For many, ancient woodlands mean wildflowers, birds, insects. For me, they mean #lichens, #fungi, #algae and #slimemoulds! Trees are a constant of course. Identifications where possible in alt-text. All from a small ancient wood in Sheriffhales, Shropshire, England.

I've found their website but no details on how wildlife affected, just broad statements. I don't have time to chase this. As you posted about it perhaps you might follow up. #Lichens important part of peatland ecosystems which should not all be bog.

Chaenotheca furfuracea- Sulphur StubbleLichen

Spotted this beauty yesterday in the Oakland Hills on some exposed roots overhanging a trail. It's distributed all over the northern hemisphere and usually like humid pockets

Most likely the lichen Verrucaria nigrescens on a limestone gatepost although you have to be careful beyond genus level with these and usually need a microscope to differentiate species #lichens

1/2 Blennothallia crispa on basic or calcareous-washed sandstone in disused quarry. Given acidic substrate, I might have assumed Collema flaccidum. But having seen other #lichens on quarry wall that also prefer basic/calcareous substrates, I took sample to check. Nostoc #cyanobacteria in clusters…

A tall, narrow waterfall cascades over a rocky ledge. Golden lichen (actually a lime green color) covers a significant portion of the face of the rock wall to the right of the falls. Green leaves from big leaf maple obscure part of the view. Trees grow on the cliff at the top of the falls.

Latourell Falls. The rock wall to the right of the falls is covered in beautiful golden lichen (Pleopsidium flavum). #WaterfallWednesday #Oregon #hiking #waterfalls #photography #PNW #lichens

Here's Peltonia grisea. I have just learnt that this is the current name of Physconia grisea, according to the Index Fungorum. P. perisidiosa and 3 other species have been moved to the same new genus.

Stoped to listen to a #chiffchaff & noticed #Larch flowers, cones and #lichens - what’s not to lichen?

Took this wee beauty on my iPhone even though I had my big camera & lens too 😊 🏴󠁧󠁢󠁳󠁣󠁴󠁿💚
