Metulochaete

Metulochaete Alvarenga 2019, in Spirin et al., Mycological Progress, 18, 1079-1099 (2019)

Etymology: Metulochaete (in Latin) the name refers to metuloid cystidia covering hymenophoral spines.

Diagnosis: Basidiocarps effused, continuous, pale-colored, gelatinous to waxy-arid, smooth or covered by sterile spines. Hyphal structure monomitic; hyphae clamped, hyaline. Hyphidia present, branched. Cystidia metuloid, covering hymenial spines. Basidia 4-celled, sessile, ovoid. Basidiospores thin-walled, allantoid, straight to slightly curved. On wood remnants.

Effused basidiocarps and sterile spines densely distributed on the hymenial surface make Heterochaete sanctaecatharinae (= Heterochaetella cystidiophora) similar to Heterochaete s.l. However, the latter genus is polyphyletic (Malysheva & Spirin 2017, Alvarenga et al. 2019), and no other species addressed to it possess heavily encrusted, thick-walled
