Chen & L.W. Zhou , sp . nov . ( Figs. 3–4 ) MycoBank no.: MB 815785 Differs from other Hyphodontia species by hydnoid hymenophore, buff-yellow to dark brown spines when dry, a monomitic hyphal structure with fairly thick-walled generative hyphae, presence of cystidia, and subglobose to broadly ellipsoid basidiospores measured as 3.2–4 × 3.0–3.5 μm. Type .— CHINA . Jiangxi Prov. : Nanning, Fenyi County, Dagang Mountain, alt. 500 m , on rotten angiosperm wood, 19 September 2008 , Dai 10526 ( holotype , BJFC!). Etymology .— Subefibulata (Lat.) referring to the species similar to H. efibulata J. Erikss. & Hjortstam. Basidiocarps. —Annual, resupinate, inseparable, corky upon drying, up to 11 cm long, 2.5 cm wide, and 2.2 mm thick at center, without odor or taste. Hymenophore hydnoid. Fresh spines cream and soft, buff-yellow to dark brown when dry, up to 2 mm long, 3–5 per mm across base. Margin cottony, buff to grey buff, up to 1 mm wide. Subiculum very thin, soft corky, cream to buff, up to 0.2 mm thick. Hyphal structure.— Hyphal system monomitic; generative hyphae with simple septa, IKI–, CB+; tissue unchanged in KOH. Subiculum. —Generative hyphae hyaline, thick-walled, frequently branched, interwoven, flexuous, 3.5–6 μm in diam. Hymenophoral trama. —Generative hyphae hyaline, thick-walled, moderate branched, straight, more or less subparallel along the spines, 2–4 μm in diam. Hymenium .— Bladder-like to clavate cystidia present, hyaline, thin-walled, 35–55 × 5–8 μm; basidia clavate, with a simple basal septum and four sterigmata, 10–13 × 3.5–5 μm; basidioles dominant, in shape similar to basidia, slightly smaller than basidia. Spores.— Basidiospores subglobose to broadly ellipsoid, hyaline, thin-walled, usually bearing one guttule, smooth, IKI–, CB–, (3.0–)3.2–4.0 × (2.8–)3.0–3.5 μm, L = 3.63 μm, W = 3.10 μm, Q = 1.12–1.17 (n = 60/2). Additional specimen examined.— CHINA . Hainan Prov. : Changjiang County, Bawangling Nature Reserve, alt. 800 m , on rotten angiosperm wood, 9 May 2009 , Dai 10803 ( paratype , BJFC!).
