Allotrechispora – Facesoffungi number: FoF 12857

Allotrechispora L.W. Zhou & S.L. Liu

MycoBank number: MB 559877; Index Fungorum number: IF 559877; Facesoffungi number: FoF 12857;

Description

Basidiomes annual, resupinate, effused, thin, soft, loosely attached to the substrates. Hymenophore smooth to tuberculate, white to cinnamon-buff, cracked with age. Hyphal system monomitic, generative hyphae with clamp connections, hyaline, thin-walled. Cystidia absent. Basidia subcylindrical to subclavate, hyaline, thin-walled, with four sterigmata and a basal clamp connection. Basidiospores oblong ellipsoid to ellipsoid, hyaline, thin-walled, smooth, inamyloid, indextrinoid, acyanophilous. On wood.

Type species: Allotrechispora gatesiae L.W. Zhou, S.L. Liu & T.W. May.

Notes: Compared to other genera in Trechisporales, Allotrechispora is characterized by cream to cinnamon-buff, corticioid basidiomes, a monomitic hyphal system, absence of isodiametric subhymenial hyphae, absence of cystidia, and smooth, oblong ellipsoid to ellipsoid basidiospores. Allotrechispora is phylogenetically closest to Fibrodontia (the clade containing both genera has BS = 74%, BPP = 0.99; Fig. 3), and these two genera are more or less similar by the absence of cystidia and smooth, ellipsoid basidiospores. However, Fibrodontia differs in the odontioid hymenophore and a dimitic hyphal system.
