No lichen I’ve ever seen…

I don’t see any algae anywhere, either.

Not resupinate polypore.

Looks like a lichen. See the upper portion of the 2nd photo. Part of the surface has been eroded down to what appears to be the underside, which is black. Also what appear to be black specs on the surface may actually be lichen spore-bearing structures. I’m going to suggest lichen.

The site of this observation was not too good for me.

In fact, the fungus was at a level higher than I could watch something and it was difficult to obtain the photographs. So I can not add details beyond that are visible in photographs. I can not guarantee the existence of pores, and increasing the 2nd photo I do not think they exist. Also do not see any trace of a lumpy, bumpy, wrinkled surface, as in the species proposed by darv.

is somewhat grainy (high ISO?) but if zoomed up, it looks like it has angular pores.

No pores, it’s not a polypore. It is a crust with a lumpy, bumpy, wrinkled surface. A common synonym is Meruliopsis corium.

Thank you all for your participation.

Regarding the proposal of darv, having seen some pictures on the internet, it seems to me that Byssomerulius corium has pores larger than my specimen, since they are clearly visible on photos.

2nd photo indicates it to be a resupinate polypore.
