Lichenologist 6: 141 (1974).
Protolog: Thallus terricolous, specimina examinata sine podetia. Squamulae thalli primarii 1-4 mm altae et 2-6 mm longae, persistentes, ascendentes, raro confertae et erectae, plus minusve incisae, margine recurvato, supra minute rugosae, cinereo-glaucescentes, infra albidae. Cortex squamularum primariorum 30-90 µm crassus, sine colore vel dilute brunnescens; medulla 180-340 µm crassa; stratum algaceum plus minusve interruptum; cellulae algarum 7-15 µm diametro, globosae, ad Trebouxia pertinens. Apothecia et pycnidia non visa. Medulla K+ flava, C-, KC-, PD+ flavorubescens. Thallus atranorium at acidum psoromicum continens.
