Type.
China. Yunnan Province: Kunming, Wild Duck Park, 2 August 2016, on fallen angiosperm branch, Dai 16892 (holotypes: BJFC 022998).
Etymology.
" Acutimarginata " (Latin): referring to the species with a sharp margin of fruiting body.
Description.
Basidiocarps annual, effused-reflexed to pileate, broadly attached, without taste or odor and soft corky when fresh. Pilei conchate, laterally fused, convex towards margin, projecting up to 1.5 cm, 7 cm wide and 6 mm thick at base. Pileal surface yellowish brown to dark brown, velutinate, concentrically sulcate with zoned; margin acute, yellowish brown. Pore surface yellowish brown when dry, glancing; margin distinct, yellowish, up to 2 mm wide; pores circular to angular, 5-7 per mm; dissepiments thin, entire. Context yellowish brown to dull brown, corky, up to 3 mm thick. Tubes yellowish brown, paler than context, corky, up to 3 mm long.
Hyphal structure.
Hyphal system dimitic; generative hyphae simple septate; tissue darkening but otherwise unchanged in KOH.
Subiculum.
Generative hyphae rare, hyaline to pale yellowish, thin- to slightly thick-walled, occasionally branched, 2-3.5 μm in diam; skeletal hyphae dominant, yellowish brown, thick-walled with a wide lumen, unbranched, aseptate, interwoven, 2-4.3 μm in diam.
Tubes.
Generative hyphae hyaline, thin-walled, occasionally branched, 2-3 μm in diam, occasionally encrusted at dissepiment edges; skeletal hyphae dominant, yellowish brown, thick-walled with a wide lumen, unbranched, aseptate, straight, subparallel along the tubes, 2-4 μm in diam. Irregular crystals occasionally present among trama and hymenia.
Hymenium.
Hymenial setae rare, mostly originating from tramal hyphae, subulate, dark brown, thick-walled, 20-40 × 3-7 μm; cystidioles frequent, fusoid, sometimes covered with crystals, hyaline, thin-walled, 16.5-26 × 4-6.5 μm; basidia broadly clavate, with four sterigmata and a simple septum at the base, 14-17 × 4.8-6.5 μm; basidioles similar in shape to basidia, but slightly smaller. Basidiospores cylindrical, hyaline, thin-walled, smooth, IKI–, CB–, (7 –)7.5–9(– 9.8) × (2.2 –)2.5– 3.2 μm, L = 8.12 μm, W = 2.87μm, Q = 2.73-2.95 (n = 60/2).
