yellow. — Stipe cylindrical, at íirst stuffed, then hollow, felted, mealy

adnate, concolorous, at length brown. — Spores ellipsoidal,
curved, smooth, pale brown, with or without guttulae,

Sterile cells and tomentose-íibrillose, flaxen. Margin somewhat incurved,
spores x 500. covered with white fibres. Stipe 5—6 cm long, 3—5 mm
