Hebeloma radicosum

A species typical of beech woods, characterized by its long rooting stipe.

Suprapellis with a layer composed of filamentous hyphae, 1.5-3 µm wide, hyaline, widely separated by gelification, septate with clamp connections; beneath these lie much broader, polymorphic hyphae with short septa and yellowish intracellular pigment inside.

Cheilocystidia cylindrical, sinuous, some slightly capitate, 30-50 µm long and 6-10 µm wide.

Basidia cylindric-clavate, 25-30 µm long and 6-8 µm wide, with basal clamps, 4-spored.

Spores ellipsoidal to amygdaliform, thick-walled and moderately verrucose, yellow under the microscope, with darker warts, a slightly eccentric apiculus at one end, dextrinoid in Melzer's reagent.
