Inocybe praetervisa

A fairly widespread Inocybe typical of deciduous and mixed forests, with an umbonate cap, radial fibrils, and caulocystidia extending to mid-stipe.

Pileipellis composed of parallelly arranged hyphae, 5-10 µm wide, with yellowish-brown encrusting intracellular pigment, septate and partially clamped.

Caulocystidia extending down to mid-stipe, fusiform with apical crystallizations.

Cheilocystidia fusiform, 40-75 µm long and 12-20 µm wide, walls up to 3 µm thick, with abundant hyaline apical crystallizations, intermixed with thin-walled, clavate to pyriform cells.

Pleurocystidia similar in morphology and dimensions to cheilocystidia.

Basidia clavate, 25-30 µm long and 10-12 µm wide, with basal clamps, 4-spored.

Spores oblong, nodulose, with prominent protuberances, yellowish-brown under the microscope, indextrinoid in Melzer's reagent.
