A tiny Ramalina #lichen (could be R. farinacea, difficult to say because it's too young). The bright orange spots in the background are created by Trentepohlia aurea alga

It’s a fairly common Xanthoria parietina (aka Common Sunburst #lichen), though this particular specimen seems to be infected by a certain lichenicolous fungus - which could explain its discoloration and tiny dark spots; perhaps Lichenoconium xanthoriae?

This is a more zoomed-out view of how the lichen grows

Cladonia #lichen (I think it's C. caespiticia, or Stubby-stalked Cladonia)

One more Cladonia #lichen - possibly Cladonia floerkeana

Also Cladonia (possibly Cladonia chlorophaea, or Mealy Pixie Cup #Lichen - intermixed with 'other' Cladonias)

Cladonia #lichen (possibly Cladonia macilenta aka Lipstick Powderhorn Lichen)

It resembles Peltula, eg Peltula euploca. The lichen doesn't grow here in NL but I've seen it in Switzerland - and mainly on rocks

Not #lichen (definitely not lichen :) It's a moss, and a very common one. So common that it used to be called just Bryum capillare (from Greek βρύον, brýon - literally 'moss'). It was later split into Rosulabryum capillare, and most recently to Ptychostomum capillare {πτύχη στόμα, folded mouth}

This is how Hypogymnia #lichen *usually* look

Licheomancy™ @licheomancy.bsky.social · Sep 1

This is Hypogymnia (Tube #Lichen), most likely Hypogymnia physodes, showing an unusual bluish-grey hue on the lobes (instead of more common pale green). No idea why this happened; one possible explanation is the metal sign planked above it (you see its green edge in the picture)

A patch of Hypotrachyna (aka Loop #Lichen, possibly H. revoluta) growing on a moss pad on bark; it’s *mainly* Hypotrachyna, though other lichens are present too. The second close-up shows the lichen’s lobes covered with soredia

This may *look* like a #lichen, but it’s in fact a filamentous mat of green algae (Klebsormidium) on bark. In theory it can be a lichen photobiont, but in practice that rarely happens (if at all). I believe we still don’t quite understand why some algae become lichen partners while others don’t

This is a 'borrowed knowledge', I look at the maps of the Italian lichenological community and they tend to ID it as Psilolechia lucida (aka Sulphur Dust Lichen)

Physcia adscendens {Hooded Rosette #Lichen}, with, well, the 'hoods' at the ends of its thallus lobes, and characteristic rhizines (they are *not* roots, more like hooks to anchor lichen to the surface)

Pale green-grey foliose lichen growing on tree bark, likely Physcia adscendens, with its characteristic hood-like tips of lobes and white rhizines

Well, #lichens; mainly jewellery-like Lecanora but also a few more

I'd go for Lecidella #Lichen; in the absence of chemicals the holy war between the Church of Lecidella and the Church of Buellia will stay unresolved

Close-up of a tree branch with a pale yellow-grey crustose lichen, dotted with many small black apothecia; most likely Lecidella

Here in NL I'd go for Alyxoria culmigena (in Dutch known as Rivierschriftmos, literally River script-moss); but I saw this one in Italy so it's most likely Alyxoria varia (aka Bark Scribble #Lichen)

Close-up of tree bark with a crustose lichen, many thin black scribble-like fruiting bodies (lirellae) scattered across the cracked pale surface; possibly Alyxoria varia
