Truncospora Pilát 1953, in Cui, et al., Fungal Diversity 97, 137392 (2019)

Diagnosis: Basidiocarps annual to perennial, pileate. Pilei applanate to ungulate, glabrous, cream to grayish brown. Pore surface white to ochraceous; pores large; dissepiments thick, entire. Context white to ochraceous, corky. Tubes concolorous with pore surface, corky. Hyphal system dimitic; generative hyphae hyaline, thin-walled, rarely branched, bearing clamp connections; skeletal hyphae dominant, hyaline, subsolid to thick-walled with a wide lumen, usually unbranched, interwoven, strongly dextrinoid, cyanophilous; tissues unchanged in KOH. Cystidia absent; cystidioles variably present. Basidiospores ellipsoid, truncate, hyaline, thick-walled, smooth, strongly dextrinoid, CB+

Type species: Truncospora ochroleuca (Berk.) Pilát 1953, in Cui, et al., Fungal Diversity 97, 137392 (2019)

Notes: Truncospora is a cosmopolitan genus with about eleven species accepted worldwide (Pila´t 1953; Corner 1989; Decock & Ryvarden 1999; Decock 2011; Zhao & Cui 2013; Spirin et al. 2015). Morphologically, it is characterized by relatively small, pileate basidiocarps, and truncate, variably (strongly) dextrinoid basidiospores (Zhao et al. 2013). Phylogenetically, it forms a clade distinct from the Perenniporia sensu stricto clade (Zhao & Cui 2013; Zhao et al. 2013).
