Cystolepiota seminuda

Cellular cutis, formed by hyaline subglobose to ovoid hyphae of large size (up to 70 µm in diameter), mixed with scarce very slender filamentous hyphae (up to only 3 µm wide).

Lamellar edge homomorphic, without differentiated elements from basidia or basidioles.

Basidia cylindric-clavate, very short, only up to 17 µm long, without basal clamp connections, 4-spored.

Spores small, ellipsoidal, smooth, hyaline, thin-walled, with a lateral apiculus, faint granular content, inamyloid in Melzer's reagent.
