Pileipellis composed of filamentous, interwoven hyphae, 4 to 7 µm wide, with pale yellowish intracellular pigment, septate and clamped.

Cheilocystidia and pleurocystidia scattered, chrysocystidia-like, clavate to fusiform, 25 to 40 µm long and 8 to 13 µm wide.

Basidia cylindrical-clavate, 18 to 25 µm long, 6 to 7 µm wide, with a simple base, 4-spored.

Spores ellipsoidal, smooth, thick-walled, brownish under the microscope, 7 to 8.5 µm long, 4 to 5 µm wide, with a minute slightly eccentric apiculus at one end, without a clearly visible germ pore, and with subtle granular content inside.
