Acraquia, route PE-3SC, km 7, 7 km from Pucara, Sapallanga, 4260 m, 12º19′53”S, 74º57′56”W, 26 Apr 2017, leaves and twigs of Baccharis sp., Lado 25321b (MA-Fungi 96480), Lado 25322b (MA-Fungi 96482). Notes. This species has an anastomosed capillitium, and the spores traversed by a pale equatorial band. Similar to Diderma spumarioides (Fr. & Palmquist) Fr., with whitish hypothallus and clustered sporophores, yet the spores, in this species, lack the equatorial band, and the capillitium is not generally anastomosed. Buyck (1988) reported that the pale band may be exceptionally absent in some specimens, and if so, the peridium appears fragmented.
