Hypholoma ericaeoides

A generally gregarious species fruiting among grasses.

Pileipellis with a thin superficial layer of filamentous hyphae, 4-7 µm wide, with brown surface incrustations; beneath these hyphae lies a thicker layer of ovoid to ellipsoidal hyphae up to 30 µm wide, thick-walled, with brown intracellular pigment.

Cheilocystidia very abundant, fusiform to lageniform with a long neck, 25-45 µm long and 5-10 µm wide.

Pleurocystidia not observed, although according to literature scattered chrysocystidia up to 55 µm long may occasionally be present.

Basidia clavate, 22-28 µm long and 7-8 µm wide, with basal clamps, 4-spored.

Spores ellipsoidal, thick-walled, yellowish-brown under the microscope, with an eccentric apiculus at one end and faint granular internal content.
