Sterile crustose lichen, on granite.
THALLUS: light gray, thick, non-lobate, definite margin, tiny-pustulate, sterile, cortex K+ yellow turning orange or reddish-orange
There are few gray saxicolous crusts with soredia/isidia with stictic-like acid
in the cortex. This was surprisingly easy to identify in , where they
discuss specimens from the San Gabriels in particular as having “isidia or a
warted areole surface” (instead of soralia). It seems likely that this is not
the correct name for this species, but this is clearly the best name to place
on it at the moment until more research is done (by someone else, thankfully).
(They are calling it “Aspicilia aff. simoensis”, which I’m guessing means
that it merely “looks like” A. simoensis.)
