Hebeloma hiemale

An autumn-fruiting species with a fruity odor and bitter taste.

Suprapellis with a layer of hyaline hyphae, 1.5-5 µm wide, widely separated by gelification, septate and with prominent clamps; beneath this lies a layer of broad, polymorphic hyphae, almost cellular in appearance, with abundant yellowish intracellular pigment inside.

Cheilocystidia cylindrical, some slightly widened at the apex (subcapitate), 50-70 µm long and 6-9 µm wide.

Basidia cylindric-clavate, 33-40 µm long and 8-10 µm wide, with basal clamps, 4-spored.

Spores ellipsoidal to amygdaliform, thick-walled and moderately verrucose, yellowish-brown under the microscope, with an eccentric apiculus at one end, dextrinoid in Melzer's reagent.
