Melanoderma B.K. Cui & Y.C. Dai 2011, in Cui, et al., Fungal Diversity 97, 137392 (2019)

Diagnosis: Basidiocarps perennial, pileate to effused-reflexed. Pilei circular to irregular shaped. Pileal surface dark reddish brown to blackish brown, concentrically zonate, glabrous; margin obtuse. Pore surface white when fresh, cream buff when dry; pores circular; dissepiments thick, entire. Context cream-buff, woody hard. Tubes cream-buff, woody hard, stratified. Hyphal system dimitic; generative hyphae bearing clamp connections; skeletal hyphae dextrinoid, CB+; tissues unchanged in KOH. Cystidia clavate to ventricose, hyaline, thin-walled, usually apically encrusted. Basidia clavate, with four sterigmata and a basal clamp connection. Rhomboid crystals frequently present in trama and hymenium. Basidiospores cylindrical, hyaline, thin-walled, smooth, IKI, CB–.

Type species: Melanoderma microcarpum B.K. Cui & Y.C. Dai 2011, in Cui, et al., Fungal Diversity 97, 137392 (2019)

Notes: Melanoderma is characterized by a perennial growth habit, pileate to effused-reflexed basidiocarps with a blackish crust at pileal surface, a white to cream-buff pore surface, and small, round pores, a dimitic hyphal system with clamped generative hyphae, dextrinoid and cyanophilous skeletal hyphae, cylindrical, thin-walled, nonamyloid, non-dextrinoid and acyanophilous basidiospores, and lack of hyphal pegs and dendrohyphidia (Cui et al.2011).
