Nothocorticium

Nothocorticium Gresl. & Rajchenb. 1999, in Gorjón, Studies in Fungi 5(1), 245 (2020).

            Diagnosis: Basidiome resupinate, orbicular to effused, hymenial surface smooth, velutinate or felty under the lens, pinkish or pale brown coloured, margin fibrillose or forming white hyphae strands developing into the bark. Hyphal system monomitic, hyphae simple-septate, thin- to thick-walled. Hyphidia abundant, filiform, strongly encrusted, simple or with few straight branches. Cystidia absent. Basidia narrowly clavate, large, sinuous, with 2 prominent sterigmata, simple septate at the base. Basidiospores cylindrical or slightly curved, large, smooth, thin-walled, guttulate, IKI–.

            Nothocorticium is characterized by the orbicular to effused basidioma that develop marginal white strands penetrating into the wood, smooth hymenophore, simple-septate hyphae, large bisterigmatic basidia, large cylindric and thin-walled basidiospores, and encrusted, thick-walled and simple or branched (usually two or few branches) hyphidia. It is a common species and easy to identify, even in the field. It is distributed in the Patagonian Andes of South Sudamerica (Greslebin & Rajchenberg 1999). Nothocorticium resemble morphologically Corticium, Dendrocorticium, and Marchandiopsis. Preliminary molecular analysis seems to indicate that Nothocorticium is related to Clavulicium macounii (Burt) J. Erikss. & Boidin ex Parmasto (K-H. Larsson, pers. comm.).
