Cerrena unicolor

Hyphal system trimitic, with thick-walled skeletal hyphae, clamped generative hyphae, and slender branched binding hyphae.

Although lacking clearly differentiated cystidia, it presents scattered fusiform cystidioles in the hymenium, somewhat smaller than the basidia.

Basidia clavate and 4-spored with basal clamp connections.

Spores ellipsoidal, smooth, hyaline, thin-walled, without granular content inside, with a discreet lateral apiculus, inamyloid in Melzer's reagent.
