Esslinger equates those two species, too

I’ll make sure MO is updated.

Thomson equates the two (P.hirsuta & P.cernohorskyi).

I’ll revisit the place and take more photos there, although I doubt I can capture those hairs – they’re almost transparent. I tentatively logged this as P.orbicularis , and only bothered with photos and samples because that county didn’t have a record of that species. Now I know better. According to Thomson, P.cernohorskyi “has been collected quite widely” in WI, but this is the first time I encountered one. Perhaps I’ve been overlooking it thinking it was P.orbicularis

Too bad, it looks really neat under the scope, doesn’t it?

Cortical hairs

I don’t think it’s visible on any of these photos, but the specimen clearly shows pale cortical hairs on the top surface of the thallus and its margins. I thought it was P.orbicularis , so I didn’t spend much time with it in the field.
