I have no notes of Ochrolechia from that packet or from any other that day. But I do have notes about there being exclusively 4 spores per ascus, in contradiction to the 8 D. scruposus is supposed to have. But then I find that to be the case in every specimen I’ve ever looked at.

Jason, this is specimen #5132012-7 where you found some Ochrolechia in the packet.

I found just a couple of “proper” apothecia (or not). They’re as tiny as craters, except the epithecium is just slightly “submerged”.

Good idea, but I’m not convinced

The craters arejust too small. Surely a thallus that well-developed would have at least a few proper apothecia? The spot tests are “odd” for Diploschistes but there should be at least some hint of red.

Diploschistes scruposus?

Lower cortex seems to be lacking, but in places crust pops off, taking thin layer of substrate with it, so lower surface looks like bunch of grains of sand interwoven with hyphae. Apothecia are deeply immersed forming “craters”. Unfortunately, non of the chem reaction typical for Diploschistes show in this specimen – the only coloring is week yellowich with K test. No reds, no purples, nothing with C test at all. Otherwise, as much magnification as I could sqeeze out of my magnified photos, they’re very similar to Diploschistes as shown by Sharnoff and others.

I’m stumped

I want to say Pertusaria, but I really have no clue. I don’t suppose you walked away with a little flake of this, by any chance? [Yes, I see you did, I can’t read too good.]
