Pyrofomes

Pyrofomes Kotl. & Pouzar 1964, in Cui, et al., Fungal Diversity 97, 137–392 (2019)

Diagnosis: Basidiocarps perennial to annual, pileate to resupinate. Pilei buff to brick or blackish brown. Pore surface buff to reddish brown; pores round to angular; dissepiments thin to thick, entire. Context buff to reddish brown. Tubes concolorous with pore surface, hard corky. Hyphal system dimitic to trimitic; generative hyphae bearing clamp connections; skeletal hyphae dominant, yellowish brown, slightly dextrinoid to non-dextrinoid, cyanophilous or not, unchanged in KOH. Cystidia absent; cystidioles variably present. Basidia clavate, with four sterigmata and a basal clamp connection. Basidiospores usually ellipsoid, truncate, yellowish to brownish, thick-walled, smooth, IKI–, CB+.

Type species: Pyrofomes demidoffii (Lév.) Kotl. & Pouzar 1964, in Cui, et al., Fungal Diversity 97, 137–392 (2019)

Notes: Pyrofomes was established by Kotlaba and Pouzar (1964), and the species of the genus usually have colored (especially reddish to reddish brown) basidiocarps, a dimitic to trimitic hyphal system, clamped generative hyphae, slightly dextrinoid to non-dextrinoid skeletal hyphae, and thick-walled, colored and truncate basidiospores (Ryvarden & Johansen 1980; Gilbertson & Ryvarden 1987; Corner 1989; Ryvarden 1991; Ryvarden &Gilbertson 1994; Wright et al. 1996). Pyrofomes is closely related to Perenniporia, separated mainly by its reddish basidiocarps and colored basidiospores. Pyrofomes albomarginatus (Zipp. ex Le´v.) Ryvarden was reported from Hainan Province of southern China (Dai & Cui 2010), it was included in this genus mainly by its reddish basidiocarps, but its generative hyphae are simple-septate and covered by crystals, its basidiospores are allantoid, hyaline, thin-walled and negative in Melzer’s reagent and cotton blue (Dai & Cui 2010), which are quite different from other species in the genus, it should be moved to other genus. However, Cui et al. 2019 didn’t include P. albomarginatus in the study.
