Alloexidiopsis schistacea

Alloexidiopsis schistacea L.W. Zhou & S.L. Liu 2022, in Li et al., Frontiers in Microbiology, 13 (no. 894641), 1-12 (2022).

Etymology: schistacea (Latin), refers to the slate-like color (grayish) of hymenophore.

Diagnosis: Characterized by grayish hymenophore with small tubercles. Basidiomes annual, resupinate, membranaceous, becoming leathery upon drying, closely adnate, widely effused, up to 15 cm long, 2.5 cm wide, about 200 μm thick. Hymenophore smooth, covered by regularly arranged sterile spines, greyish when fresh. Margin gradually thinning out, thin, concolorous with or slightly darker than subiculum. Hyphal system monomitic; generative hyphae with clamp connections. Subiculum composed of crystal clusters and agglutinated hyphae; subicular hyphae hyaline, thin-walled, frequently branched, closely interwoven, 23 μm in diam. Cystidia cylindrical with an obtuse apex, 2550 × 46 μm, with a clamp connection at base. Hyphidia arising from hyphae, nodulose or branched, hyaline, thin-walled, 2040 × 1.53 μm. Basidia ellipsoid to ovoid, longitudinally septate, four-celled, embedded, 1520 × 710 μm. Basidiospores cylindrical to broadly cylindrical, slightly curved (allantoid), hyaline, thin-walled, smooth, acyanophilous, inamyloid, indextrinoid, with oily inclusions, (8.5−)9.511(−12.5) × (4.3−)4.55.5 μm, L = 10.4 μm,W = 5.0 μm, Q = 2.1 (n = 30/1).
