Diagnosis.

Xylodon granulanoides differs from X. granulans . by its varied cystidia and broadly ellipsoid, thick-walled basidiospores measuring 4.7–5.3 × 3.6–4.1 μm.

Holotype.

China • Yunnan Province, Wenshan, Pingbian County, Wenshan National Nature Reserve , 23°22'N, 103°93'E, evel. 1753 m asl., on fallen angiosperm branch, 28 July 2019, CLZhao 17253 ( SWFC).

Etymology.

Granulanoides (Lat.) refers to the new species’ resemblance to Xylodon granulans .

Description.

Basidiomata. Annual, resupinate, adnate, membranous, without odor or taste when fresh, brittle when dry, up to 5.3 cm long, 2.5 cm wide, and 0.1 mm thick. Hymenial surfaces grandinioid, white to cream when fresh, cream to slightly buff upon drying. Sterile margin thin, indistinct, slightly cream, up to 1 mm.

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

Hymenium. Cystidia numerous, subclavate to cylindrical, or slightly subcapitate, hyaline, thin-walled, 9.5–29.0 × 4.0–9.5 μm; cystidioles are present, subcapitate, hyaline, thin-walled, 13.5–21.0 × 5.0–9.0 μm. Basidia subcylindrical to clavate, hyaline, thin-walled, with four sterigmata and a basal clamp connection, 11.0–16.0 × 4.0–5.5 µm; basidioles dominant, in shape similar to basidia, but slightly smaller. Basidiospores. Broadly ellipsoid, part has a large drop of oil, hyaline, slightly thick-walled, smooth, IKI –, CB –, (4.6 –) 4.7–5.3 (– 5.3) × (3.4 –) 3.6–4.1 (– 4.2) μm, L = 4.92 μm, W = 3.90 μm, Q = 1.26 (n = 30 / 1).
