Thickets of Cladonia #lichen (C. rangiferina or perhaps C. portentosa)

Xanthoria parietina {Sunburst #Lichen} is perhaps one of the most omnipresent and 'unremarkable' lichens in the Northern Hemisphere; yet also one of the most surreally beautiful

The weather was bleak, nearly rainy all day, so I didn’t take a camera - all the photos today were made by phone. This is large Punctelia, possibly Punctelia subrudecta {Powdered Speckled Shield #Lichen}.

Giant patch of Parmelia sulcata {Shield #Lichen}

Most often I try to ID the #lichen I show here, but in some cases that does not seem to be important, it's simply a nice lichen (also moss, in this case)

I think it's what is known as Candelariella medians {or Lobed Goldspeck #Lichen}

See? no pleating. This is what I think Ptychostomum capillare {Capillary Thread #Moss}

In rare cases I share not only #lichen but other 'morganic' species, like moss. This is a fairly unusual case: normally the setae grow more like grass, standing separately, but here the stalks of Ceratodon purpureus (aka Redshank, or Fire #Moss) form little plaits, intertwining with each other.

This was actually #lichen, I swear. I rarely show anything here but lichen

Graphis scripta agg. {Common Script #Lichen} A journal of lichenology is named Graphis Scripta after the lichen.

A large sunlit mat of Physcia caesia {Blue-gray Rosette #Lichen}

Cladonia, possibly Cladonia fimbriata {Trumpet #Lichen}. AI suggests unusually poetic description, comparing it to the 'miniature forest of goblets, lit by warm golden light'; it's getting better and better, with every hour

Physcia adscendens (Hooded Rosette #Lichen) grows in a small knot hole of an aspen

Fifty shades of light and shadow of Lobothallia radiosa #lichen. Okay, maybe not 50, but still quite a spectrum

Small rosette of Calogaya, probably C. pusilla {Tiny Firedot #Lichen} rather than C. saxicola but it's hard to say from a photo alone

Bright yellow-orange Flavoplaca #lichen covers the rock so heavily that the surface looks dusted with gold. My guess it's F. flavocitrina but could be others, hard to say from this image only. There patches of other lichen too, most notably rosettes of Calogaya

Circinaria calcarea {Calcareous Rimmed #Lichen} spreads across stone in multiple patches, creating a cracked mosaic, like a map of tiny kingdoms.

Physconia, possibly P. enteroxantha {aka Yellow-edged Frost #Lichen}. In Dutch the lichen is know as 'rijpmos', hoarfrost lichen

Parmelia sulcata {I used to write here 'aka Shield #Lichen', or Cracked Shield Lichen; but then I learned that iNat had introduced a new nickname - Netted Shield Lichen. It likely alludes to the 'nets' of characteristic cracks on the lichen’s lobes. Sulcata comes from the Latin for 'furrowed'}

The War of Lichen: Lecidella (L) and Lecanora (R), possibly L. chlarotera {Dusted White-Rim #Lichen}

Punctelia, possibly P. subrudecta {Powdered Speckled Shield #Lichen}; not very well visible here, but some of the lobes were densely covered by laminal pycnidia

Flavoparmelia caperata {Common Greenshield #Lichen} with a very heavily sorediate central mass; after heavy rain, the center turned into messy lumpy cushions, resembling Lepraria powdery lichen

A tiny young Philodromus spider, barely 2mm long, making its way through the thick lobes of Flavoparmelia caperata {Greenshield #Lichen}

Ramalina spp; perhaps Ramalina farinacea {Farinose Cartilage #Lichen}

Lecanora, possibly Lecanora chlarotera {Dusted White-Rim #Lichen} It's all picturesque & stuff, but some of the apothecia seem to be affected (infected?) and show orange-red stains and discoloration, perhaps caused by a lichenicolous fungus

Physcia, possibly P. aipolia {aka Hoary Rosette #Lichen}

Cladonia; *they say*, it could be C. gracilis {aka Smooth Horn #Lichen}, though it could as well be C. ramulosa. Or C. somethingelse

Myriolecis dispersa {Mortar Rim #Lichen}

Evernia prunastri {aka Oakmoss - though actually #lichen}

Hypogymnia {Tube #Lichen}, possibly Hypogymnia physodes, at the tip of the twig

Protoparmeliopsis muralis {Stonewall Rim #Lichen}; on the pavement this time

Visually the #lichen looks very much like Circinaria, eg C. contorta; the only oops is that it grows on bark (Circinaria is saxicolous lichen typically growing on calcareous rock/limestone). My best bet then is Pertusaria, eg P. pertusa. Plausible alternative IDs are welcome

Cladonia portentosa {aka Reindeer #Lichen}

Parmotrema {Ruffle #Lichens}, likely Parmotrema perlatum {aka Black Stone Flower}

Close-up of the lobe tips of Physcia adscendens (aka Hooded Rosette #Lichen)

Flavoparmelia {Greenshield #Lichen}, possibly F. soredians

Physcia, possibly P. aipolia {Hoary Rosette #Lichen}

Peltigera canina {Dog Pelt #Lichen}

Pseudevernia; possibly P. furfuracea (aka Tree Moss - but which is actually #lichen)

Physcia caesia {Blue-gray Rosette Lichen#}

Ramalina #lichen, Possibly R.fastigiata {Dotted Ribbon Lichen}. The spider, idk; don't know much about Araneae. iNat says it's Philodromus, or Running Crab Spiders; ook leuk

Cladonia #lichen; possibly Cladonia floerkeana or something

I'd say Parmotrema #lichen, perhaps P. perlatum; though it's also a bit confusing picture - it looks like a meta-symbiote of a kind, with two different lichen intermixed.

Feathery green moss dusted with pale lichen; possibly Lepraria (appropriately, Dust #Lichen)

The world of Parmelioideae #lichens in b/w

Parmotrema, likely P. reticulatum {Black Sheet #Lichen}

Same story, most likely it's Lecidella #lichen (possibly L. elaeochroma) but could be Amandinea

Coccinella septempunctata {Seven-spotted ladybird} in the vicinity of an outgrowth of Lecidella #lichen (or Buellia, no way to be certain)

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)
