Harmaja (1974) Clitocybe nebularis or Lepista nebularis, commonly known as the clouded agaric, cloudy clitocybe,[2] or cloud funnel, is an abundant gilled fungus which appears both in conifer-dominated forests and broad-leaved woodland in Europe and North America.

After much consideration by many mycologists, over some years, when it was placed for periods in both Lepista, and Gymnopus, it was placed back in Clitocybe with the specific epithet, and 1871 accreditation it retains today.Clitocybe nebularis var.

[3] The cap of the mushroom is 5–25 cm (2–8 in) in diameter, convex with an incurved margin, becoming plane to depressed in shape.

Cap colours are generally greyish to light brownish-grey, and often covered in a whitish bloom when young.

[5] This species is host to the parasitic gilled mushroom Volvariella surrecta, which is found on older specimens.
