Hornodermoporus

Hornodermoporus Teixeira 1993, in Cui, et al., Fungal Diversity 97, 137–392 (2019)

Diagnosis: Basidiocarps annual to perennial, pileate to effused-reflexed, woody hard. Pilei applanate to ungulate, glabrous, usually irregularly concentrically sulcate, dirty brown to black with a distinct crust. Pore surface white to dirty ochraceous; pores round; dissepiments thick, entire. Context pale buff to wood color, woody hard. Tubes concolorous with pore surface, hard corky. Hyphal system dimitic; generative hyphae bearing clamp connections; skeletal hyphae strongly dextrinoid, cyanophilous; tissues unchanged in KOH. Cystidia present. Basidiospores ellipsoid, truncate, hyaline, thick-walled, smooth, strongly dextrinoid, CB+.

Index Fungorum Number:  IF27305

Type species: Hornodermoporus martius (Berk.) Teixeira 1993, in Cui, et al., Fungal Diversity 97, 137–392 (2019)

Notes: Hornodermoporus was established by Teixeira (1993). Morphologically, it is similar to Perenniporia Murrill, but differs by having a black crust at pileal surface, the presence of cystidia and oblong-ellipsoid basidiospores. Previously, species in the genus were treated in Perenniporia. Recent phylogenetic studies supported that Hornodermoporus is distinct from the Perenniporia sensu stricto clade (Zhao and Cui 2013a, b, c; Zhao et al. 2013).
