  • Gills: Cream color when young, chocolate brown in age, with adnate to adnexed attachment.
  • Spores: Dark chocolate brown, subrhomboid to subovoid, thick-walled, 9 - 12 x 6 - 8 µm.
  • Stipe: 5 - 10 cm long, .5 to 2 cm thick, white, sometimes with light orange patches, fibrillose, equal to slightly enlarged near the top. Annulus fragile and membranous, white or dusted with dark brown spores. Stem base with rhizomorphic mycelium. Bluing where damaged.
  • Taste: Slightly farinaceous.
  • Odor: Slightly farinaceous.
  • Microscopic features: Pleurocystidia absent. Cheilocystidia 20 - 30 x 6 µm, fusiform or ventricose-rostrate, sometimes forked.

Distribution and habitat
