Brunneoporus hyalinus

Hyphal system dimitic, with thick-walled skeletal hyphae dominant in the trama and thin-walled clamped generative hyphae very abundant in the subiculum.

Without cystidia, although it does present in the hymenium some scattered pointed cystidioles that protrude very slightly above the level of the basidia.

Basidia clavate and generally 4-spored, though occasionally it may also present 2-spored basidia.

Spores cylindrical to very slightly allantoid, smooth, thin-walled, with a lateral apiculus, inamyloid in Melzer's reagent.
