Inocybe mixtilis

A species with a finely fibrillose cap having a pronounced umbo, nodulose spores, occurring under both conifers and broadleaf trees as well as in parks and gardens.

Pileipellis composed of filamentous hyphae arranged more or less parallelly, 5-12 µm wide, with yellowish-brown intracellular pigment, brown surface incrustations, septate and partially clamped.

Caulocystidia present over the entire stipe surface, lageniform with apical crystallizations.

Cheilocystidia fusiform to lageniform, 35-60 µm long and 15-20 µm wide, walls up to 3 µm thick, intermixed with very abundant, shorter, subglobose, clavate to pyriform paracystidia.

Pleurocystidia scattered, very similar in morphology and dimensions to cheilocystidia.

Spores nodulose, angular, with coarse protuberances, moderately thick-walled, pale yellow under the microscope, with a lateral hyaline apiculus at one end.
