Diagnosis.

Kneiffiella bubalina differs from K. subalutacea by its cream basidiomata and cylindrical to slightly allantoid basidiospores.

Holotype.

China • Yunnan Province, Wenshan, Xichou County, Jiguanshan Forestry Park , 23°53'N, 104°82'E, evel. 1730 m asl., on fallen angiosperm branch, 22 July 2019, CLZhao 15708 ( SWFC).

Etymology.

Bubalina (Lat.) refers to its buff-colored hymenial surface.

Description.

Basidiomata. Annual, resupinate, smooth, membranous, without odor or taste when fresh, up to 1.6 cm long, 1.1 cm wide, and 0.1–0.2 mm thick. Hymenial surface araneose, white to cream when fresh, buff when dry. Sterile margin thin, indistinct, slightly buff, up to 1 mm.

Hyphal system. Monomitic; generative hyphae with clamp connections, slightly thick-walled, frequently branched, interwoven, IKI –, CB –, 2.5–3.5 μm in diam; tissues unchanged in KOH.

Hymenium. Cystidia numerous, tubular, rising from subiculum with a basal clamp connection, hyaline, thick-walled except in the apical part, smooth, 103.5–162.5 × 6.0–8.0 μm; cystidioles absent. Basidia club-shaped, slight constriction in the middle part, with four sterigmata and a basal clamp connection, 10.0–14.0 × 4.5–5.0 μm; basidioles dominant, in shape similar to basidia, but slightly smaller. Basidiospores. Cylindrical to slightly allantoid, slightly narrower in apical part, hyaline, thin-walled, smooth, IKI –, CB –, 8.0–8.9 (– 9.1) × (1.7 –) 1.8–2.3 (– 2.6) μm, L = 8.41 μm, W = 2.03 μm, Q = 4.15 (n = 30 / 1).
