Specimen available

I’d thought this was Parmelia sulcata before, but now that I look at it, it’s clearly not: lobes are too broad, too thin, not strap-shaped enough, cilia to conspicuous, pseudocyphellae not obvious enough, just generally looks wrong.

I’m thinking now that it is Rimelia reticulata… which is no longer a Rimelia but a Parmotrema. Arg. A simple spot test would confirm: medulla should be K+ yellow to red (instead of C+ red as in Parmelia sulcata).


Flavoparmelia on left, Parmotrema on right. Neither is showing soredia/isidia.
