Rhodocybe truncata

A species very similar to its congener Rhodocybe gemina, long considered synonymous, with a convex to applanate pileus 4 to 12 cm in diameter, brownish; adnate lamellae pale ochre to pinkish; a cylindrical, fibrillose, very brittle stipe concolorous with the pileus; strong odor and slightly bitter taste.

Cuticle formed by cylindrical filamentous hyphae arranged more or less parallel to slightly interwoven, 4 to 6 µm wide, hyaline or with faint brownish intracellular pigment, septate with short cells and without clamp connections (simple septa).

Lamellar edge without clearly differentiated cystidia, but bearing scattered hair-like pseudocystidia; these sterile hyphae are cylindrical, filiform to fusiform, 30 to 45 µm long and 4 to 6 µm wide.

Basidia clavate, 30 to 45 µm long, 8 to 10 µm wide, simple-based (clampless) and four-spored.

Spores ellipsoidal, smooth, hyaline, thin-walled and slightly angular (with flattened facets), pale yellow under the microscope, 5 to 6.5 µm long, 4 to 5 µm wide, with a pointed apiculus at one end, containing granular oily content inside, and inamyloid in Melzer's reagent.
