Suprapellis hyphae filamentous, interwoven, slightly separated by gelification, with dark green intracellular pigment and clamped; in the subpellis are hyphae of identical morphology but broader, more compacted and less pigmented.

Without cheilocystidia, but with the lamellar edge provided with numerous hyaline terminal cells resembling basidia, slightly smaller in size.

Basidia clavate and 4-spored, some containing siderophilous granules inside.

Spores citriform to amygdaliform, pale brown under the microscope, with their surface covered in coarse darker warts and a prominent lateral apiculus.
