Cristinia rhenana

Subicular hyphae filamentous, corresponding to a monomitic hyphal system composed of rather thick-walled, clamped generative hyphae.

No cystidia observed.

Basidia cylindrical, up to 35 µm long, only very slightly and progressively widening toward the apex, with basal clamp connections, strongly cyanophilous (staining blue in cotton blue), 4-spored.

Spores ellipsoidal, smooth, hyaline, thick-walled, with a prominent slightly eccentric apiculus at one end, cyanophilous, inamyloid in Melzer's reagent.
