Aspicilia sp., possibly Aspicilia cinerea. All over the rock…. Sakura-saku Lane, Saku, Nagano #Lichen #FungiFriends
キッコウイボゴケだと思う。ぶつぶつ...。長野県佐久市さくラさく小径 #地衣類
Close-up of the apothecia of Aspicilia lichen. Apothecia have black grainy interior with white-grey rim. Individual apothecia are divided by deep cracks. Colony of Aspicilia lichen on rock. The thallus is cracked and there are apothecia in the polygon created by the cracks.

Aspicilia sp., possibly A. cinerea. Characterized by pitted apothecia. Ikenotaira, Tomi, Nagano #Lichen #FungiFriends
キッコウイボゴケだと思う。長野県東御市池の平 #地衣類
Close-up of the pitted apothecia of Aspicilia lichen. The pits are irregular in shape, with textured black interior nestled within the white-grey thallus. The thallus have deep crack and there are one to two apothecia per polygon created by the crack. Colony of Aspicilia lichen on rock. It looks like cracked clay surface with black dots.

I think this is Aspicilia cinerea but it’s sort of unclear…. Usually there’re one to three pits per polygon but this one seems to have several. Maybe they become separated by cracks later on. Iizunayama Park, Komoro, Nagano #Lichen #FungiFriends
なんだかはっきりしないキッコウイボゴケ。長野県小諸市飯綱山公園 #地衣類
Colony of Aspicilia lichen on rock. There are black pits in white-grey thallus. There are cracks that separate the sections into polygons. There are several pits per polygon.

Ah, that makes Circinaria calcarea (Aspicilia calcarea) more likely than contorta. I really should have learnt not to attempt these from a photograph by now!

First question with these is what substrate was it on as that can be very relevant. Purely from the image I'd be considering Circinaria contorta (Aspicilia contorta subsp. contorta) rather than Circinaria hoffmanniana (Aspicilia contorta ssp. hoffmanniana) or Circinaria calcarea (Aspicilia calcarea)

Aspicilia cinerea almost entirely cover the rock at the base of a stele. Saku-ra-saku lane, Saku, Nagano #Lichen #FungiFriends

Close-up of the polygonal apothecia of Aspicilia lichen. The interior is black and the rim is white-grey. The apothecia are separated by deep cracks in the thallus. Dense colony of Aspicilia lichen on rock. It covers the rock almost entirely. The lichen is white-grey with cracks, where there are one to three apothecia per polygon created by the crack.

Here's a nice close-up of some lichen. I love observing tiny crustoses because up close it looks like the surface of an alien world!
#ForestFloor #Nature #Photography #MacroPhotography #Lichen #fungifriends
Microscope photograph of crustose lichen tightly adhered to a rock surface. The thallus appears as a dense mosaic of pale gray, wart-like granules, each no more than a millimeter wide, with tiny black reproductive pits dotting some surfaces. Likely a species of Aspicilia, this lichen forms a tough, stone-hugging crust. In lichenology, crustose forms are noted for their resilience in arid, exposed habitats with minimal organic matter.

Circinaria (Aspicilia) calcarea on limestone plinth, London, England. Heavily mollusc-browsed but still recognisable with its chalk-white thallus and grey prothallus. First record for Kensington Gardens/Hyde Park, ~6th for central London. But surely more to be found on limestone structures in city.

Thanks, Graham. Acarospora impressula is a red-brown, areolate lichen. Its apothecia are immersed, but they appear more like those of Aspicilia or Circinaria than Pertusaria. Indeed, your lichen looks to me like a Pertusaria, possibly P pertusa, which can atypically occur on stone.

Aspicilia cinerea characterized by deep pit apothecia on surface separated into polygons. When there are multiple pits on a polygone, they may look like a face. Saku-ra-saku Lane, Saku, Nagano #Lichen #FungiFriends

Close-up of the apothecia pits of Aspicilia lichen. There are one to three pits on the polygon separated by deep cracks. One in the center looks like a skull. Colony of Aspicilia lichen on a stone. There are polygons with black pits within concentrated throughout the stone.

Aspicilia vs. Diploschistes. I think the one of the left is A. cinerea. Lake Matsubara, Koumi-machi, Nagano #Lichen #FungiFriends
キッコウイボゴケ（左）とキッコウゴケ（右）が拮抗している。オヤジギャク失礼。長野県小海町松原湖 #地衣類
Close-up of the apothecia of Aspicilia lichen. Apothecia are dips with black interior, white powdery rim. They are settled in polygons separated by crack. The lichen body look like it is completely covered with fine, white powder. On the left is white, powdery lichen body of Aspicilia lichen, with black apothecia. On the right is grey, cracked lichen body of Diploschistes lichen.

Close-up of the apothecia of Aspicilia lichen. There are black dots within white polygons separated by deep cracks. Mostly one dot per polygon, but some has two. Colony of Aspicilia lichen on the rock. There are dots in white polygons.

Lichens! I illustrated these as Artist-in-Residence @ Glacier Nat'l Park & Rocky Mtn Nat'l Park. One isn't allowed to collect specimens in a NP, so I noted the exact placement of the rocks bearing these specimens, brought them to my cabin to paint, then carefully returned them to their home. #sciart

Mysterious crustose lichen colony. Diploschistes or Aspicilia, but can't really tell due to the underdeveloped apothecia. The black border on the edge is remarkable. Lake Matsubara, Koumi-machi, Nagano #Lichen #FungiFriends
固着地衣類。キッウゴケかイボゴケか。長野県小海町松原湖 #地衣類
Colony of crustose lichen on stonewall. The lichen body is cracked but there seem to be no dots or pits in the polygonal cracks. The edge of the colony is black.

Sorry to hear you're poorly, Peter! I suspect you don't have Aspicilia. Aspicilia ascus tholus K/I-, but yours K/I+ blue. Tholus seems closest to Lecanora-type (see image). Many genera have this type of ascus, not just Lecanora, but it may help you rule out at least some externally similar species.

Wirth (2013) sends me via the aspicilia key to hymenelia. Lets see where this is going.

Aspicilia cinerea with deep pitted apothecia that give the appearance of skulls or faces. Bit creepy to see this around graveyards. Lake Matsubara, Koumi-machi, Nagano #Lichen #FungiFriends
骸骨みたいなキッコウイボゴケ。長野県小海町松原湖 #地衣類
Close up of the apothecia pit of Aspicilia lichen. The pits are irregularly shaped with one to three pits per section. The inside of the pit is dark grey. A section is polygonal part of the white lichen body that are separated by deep cracks. The combination of the section and pits gives the appearance of face. Colony of Aspicilia lichen on stone. There are polygons separated by crack. There are one to three dots of various shapes within the polygon section.

Circinaria (Aspicilia) hoffmanniana, Bungay, TM38/VC25 E Suffolk, England. Common but under-recorded! Only recognised as own species in 2016. Can be confused with C calcarea. N-tolerant: you'll find it even in urban and agricultural areas. New field notes to help! aspenecology.com/circinaria-a...

This is the bulk of species ID'd in my study. Might be missing one or two, but I'd have to dig through a bunch of table to find which ones. 1/2
Acarospora contigua
Aspicilia caesiocinerea
Diploschistes muscorum
Lecanora rupicola
Lecidea atrobrunnea
Lecidea tessellata
Pseudephebe minuscula

Perhaps Circinaria caesiocinerea (Aspicilia caesiocinerea) - but without detail of habitat, rock type and chemistry that's just guesswork
