Calonarius alcalinophilus

Suprapellis composed of filamentous, interwoven hyphae, widely separated by gelatinization, rather slender (2 to 5 µm wide), with abundant ochraceous intracellular pigment and clamped.

Lamellar edge without clearly differentiated elements from basidia, but with basidioliform terminal cells smaller than the basidia.

Basidia clavate and 4-spored, with basal clamp connections, up to 30 µm long; some basidia observed with ochraceous granular content.

Spores amygdaliform to citriform, rugose-walled, yellow under the microscope, with coarse darker warts and a prominent lateral apiculus.
