Etymology: ‘Fascio’ (Lat.) refers to fasciculate arrangement of hyphae in aculei, ‘dontia’ stresses the derivative origin from Hyphodontia s.l.
Diagnosis: Basidioma effused,membranaceous, cracking with age; margin thinning out, rarely abrupt.Hymenial surface minutely odontioid, whitish or cream-colored; aculei sterile except bases and consisting of projecting hyphae. Hyphal system pseudodimitic; hyphae clamped at all primary septa, colorless in water, slightly yellowish in mass in KOH, moderately cyanophilous, negative in Melzer’s reagent; skeletal-like thick-walled hyphae present in basal subhymenium and in aculeal trama; skeletal-like hyphae in aculei loosely encrusted, apically thin-walled, partly agglutinated with age. Cystidia from cylindrical to slightly moniliform and capitate. Basidia utriform to subcylindrical, with two slight constrictions, thin-walled or slightly thick-walled in lower 1/2–2/3, with four sterigmata. Spores ellipsoid, smooth, with thickened or thick wall (about 0.2–0.3 μm thick), colorless, negative in Melzer’s reagent, slightly to moderately cyanophilous.
