Lichens. Definitely lichens.
Physcia jackii and Teloschistes sieberianus #lichens growing in Australia; these are not my pics but of Stephen Axford, from the recently published book 'Planet Fungi' (by Australian mycologist Tom May). I assume it's mainly about 'fungi' and lichens pop-up only occasionally

Compared to all these micro-photo champions, own pics look pretty bleak, of course. Oh, well. Let's chose to be inspired and not demotivated ^_^ This is Trentepohlia aurea, or Orange 🧡 Rock Hair, in full bloom (it's not #lichen but alga)

Alas, no #lichen among the finalists of the Nikon's SmallWorld microphotography contest :(
№ 13 is a pretty stunning image of Arcyria major (it's slime mold) releasing spores, by Henri Koskinen from Helsinki U. yet another slime mold - Cribraria purpurea - got IoD (Image of Distinction) award

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?

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 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)

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

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)
