Description

Pileus 7–31 mm diameter, initially campanulate to hemispherical and then flat-convex to convex (Fig. 2 A). Margin involute to revolute as the basidiome develops. Hymenophore with lamellae adnate to slightly emarginate. Stipe 2–8 x 4–17 mm, central, cylindrical. Basal mycelium is absent. Spore print not obtained (Fig. 2 A). Basidiospores (9.3) 11.4 ± 1.4 (13.3) x (5.5) 6.4 ± 0.4 (7.2) µm, Q = (1.29) 1.78 (2.42), ellipsoid to amygdaliform, moderately rugulose to verrucose, heavily pigmented (Fig. 2 B). Basidia (24.0) 29, 3 ± 2.6 (34.3) x (6.9) 9.3 ± 1.6 (12.82) x (3.6) 5.8 ± 1.2 (8.47) µm, clavate, hyaline, four-spored (Fig. 2 C). Pleurocystidia (18.4) 34.3 ± 9 (48.8) x (7.6) 10.0 ± 2.1 (14.1) x (3.6) 6.1 ± 1.9 (9.4), utriform to slightly lageniform, hyaline (Fig. 2 D). Cheilocystidia (29.0) 37.8 ± 12.6 (57.79) x (7.7) 10.5 ± 1.9 (12.2) x (4.8) 5.1 ± 0.2 (5.3) x (5.2) 5.8 ± 0.4 (6.3) µm, lageniform to ventricose-fusoid and slightly fusiform, hyaline (Fig. 2 E, F). Caulocystidia (59) 63.9 ± 7.9 (78.1) x (11.2) 12.7 ± 0.7 (13), hyphoid to utriform, hyaline to slightly pigmented (Fig. 2 G). Pileocystidia were not observed. Regular lamellar context. Pileipellis is composed of prostrate to periclinal hyphae, encrusted with pigments (Fig. 2 I, J). Clamp connections were not observed.

Ecology

Growing in a coastal moss field. Basidiomata are scattered in an area with vegetation predominantly composed of Sanionia uncinata (Hedw.) Loeske.
