Collection location: Torrey Pines State Reserve, San Diego Co., California, USA [Click for map]
Crust lichen, on bark.
THALLUS: light grey to slightly greenish to slightly yellowish at margin, smooth at margin to very thickly verruculose inside, K-, KC- (except where medulla shows through), C-
MEDULLA: white, K-, KC+ pink, C+ pink
APOTHECIA: lecanorine, very thick shiny smooth rims, disk very white pruinose, epihymenium brown fading inward to yellow, hymenium clear, hypothecium conspicuously yellow, all K-, epihymenium C+ red, amphithecium filled with lots of small (10-12 µm) crystals, paraphyses narrow and loosely netted
SPORES: 8 per ascus, elliptical, 45 × 25 µm, 1 round cell inside rough greyish stuff, colorless
The key in Nash’s Flora is a bit screwy, and fails because it claims in the key that the medulla is C-, however in the description it says that it is C+ red under the apothecia.
