Gymnopilus palmicola

A Gymnopilus typical of stumps and fallen trunks of palm (Cocos nucifera).

Pileipellis with filamentous hyphae arranged more or less parallel, up to 10 µm wide, with brown intracellular pigment and surface incrustations (more abundant on the scales), with cylindrical terminal cells with rounded apices, septate and with some clamped septa.

Cheilocystidia very abundant, completely covering the gill edge, fusiform to lageniform, with a long neck and well-differentiated capitate head, up to 35 µm long and a maximum width of 10 µm.

Basidia clavate, with faint granular internal content, up to 27 µm long, mostly 4-spored.

Spores ellipsoidal to slightly amygdaliform, thick-walled and verrucose, brown under the microscope, with darker internal warts, an inconspicuous eccentric apiculus at one end, distinctly dextrinoid in Melzer's reagent.
