Typification.

China. Yunnan Province • Xishuangbanna, Wild Elephant Valley , GPS coordinates: 22°10′N, 100°51′E, altitude: 900 m asl., on the fallen angiosperm branch, leg. C. L. Zhao, 25 January 2024 CLZhao 35693 ( SWFC!) GoogleMaps .

Etymology.

Albocremeum (Lat.) refers to the new species having white to cream hymenophore.

Basidiomata.

Annual, resupinate, closely adnate, membranaceous, without odor or taste when fresh, up to 10 cm long, 2 cm wide, and 700 μm thick. Hymenophore smooth, white (60) to cream (4 A 2 / 3) when fresh, cream (4 A 2 / 3) upon drying. Sterile margin narrow, cream (4 A 2 / 3), up to 1 mm.

Hyphal system.

Monomitic; generative hyphae with simple-septa, colorless, thin-walled, smooth, rarely branched, interwoven, IKI +, CB –, 2–3 µm in diameter; tissues unchanged in KOH.

Hymenium.

Gloeocystidia subclavate, flexuous, colorless, mostly constricted in the middle, thin-walled, smooth, 33–47.5 × 5–8 µm. Basidia subcylindrical to subclavate, slightly flexuous, with a basal simple septum and four sterigmata, 22–36 × 4.5–7 µm; basidioles numerous, in shape similar to basidia.

Spores.

Basidiospores ellipsoid with a distinct apiculus, colorless, thin-walled, finely verrucose but appearing smooth by light microscope, IKI +, CB –, 9–11 × 5–7 µm, L = 9.82 µm, W = 5.84 µm, Q = 1.36–1.68 (n = 90 / 3).
