The description of L. thysanophora (2000. Bryologist 103(4): 790-793) doesn’t discuss it at all. Makes you wonder if Lecanora normally spreads by means of these radiating hyphae, but that the medulla and cortex accompany expansion immediately, thus you never see this prothallus normally except maybe as a black ring right at the edge. But in this species, it never develops cortex or a proper medulla, so the prothallus is the whole thing.
Spectacular. Wonder if there is a reason for the unusual prothallus in this species.
Brodo et al. 2001 confirms that it can grow “even on rocks”. That’s new for me.
Just realized I had a decent sample of rock-dweller.
