Hemimycena lactea

A small species typically fruiting under pines on decaying needle litter.

Pileipellis filamentous, composed of hyaline hyphae arranged parallelly to slightly interwoven, up to 6 µm wide, with emergent pileocystidia-like terminal elements, septate and with rounded apices.

Caulocystidia present and abundant, cylindrical to fusiform, sinuous, mostly capitate at the apex, 20-45 µm long and 4-7 µm wide.

Cheilocystidia cylindrical to fusiform, 15-45 µm long and 4.5-6 µm wide.

Basidia clavate, 20-26 µm long and 4.5-6 µm wide, with basal clamps, 2- or 4-spored.

Spores cylindrical to slightly fusiform, with one end more pointed at the apiculus, smooth, hyaline, thin-walled, with one or more oil or lipid droplets inside, inamyloid in Melzer's reagent.
