Cuticle filamentous, composed of cylindrical hyphae arranged more or less parallel to intermixed, 3 to 6 µm wide, with abundant orange pigment inside, septate with simple septa (without clamp connections).

Without cystidia.

Lamellar trama regular or parallel.

Basidia clavate, 25 to 40 µm long, 6 to 8 µm wide, with simple base, 4-spored.

Spores subglobose to ellipsoid, smooth, hyaline, thin-walled, with an eccentric apiculus at one end, 4.5 to 7 µm long, 3 to 4.5 µm wide, usually containing a large oil droplet inside, inamyloid in Melzer's reagent.
