Common Name: none

Synonym: Coprinus lagopus (Fries) Fries

• Pileus

  Cap 3-6 cm broad, obtuse-conic, expanding to nearly plane, umbonate, the margin recurved in age, often split or ragged from deliquescing gills; surface at first covered with erect, soft, white hairs (universal veil remnants), typically weathering away at maturity to reveal a striate, greyish-brown cuticle; flesh thin, pale grey.

• Lamellae

  Gills free, close, narrow, white soon greyish, becoming black and deliquescing in moist weather.

• Stipe

  Stipe 5-10 cm tall, 0.3-0.5 cm thick, more or less equal, fragile, hollow; surface dry, white tomentose from universal veil remnants; partial veil absent or evanescent.

• Spores

  Spores 11-13 x 6-8 µm, elliptical smooth; spore print black.

• Habitat

  Scattered on logs, decaying wood etc.; fruiting from late fall to mid-winter.

• Edibility

  Unknown.

• Comments

  This fragile, beautiful Coprinus with a revolute cap margin persists for only a few hours before senescing. The dense, erect, white hairs which cover the young fruiting body and the lignicolous habit help characterize this species.
