Magpie Inkcap

Coprinopsis picacea

Type: Gilled mushroom

Magpie Inkcap

Physical Characteristics

Bell-shaped to conical cap, initially dark brown to blackish but covered in a white universal veil that breaks into large, irregular patches or scales resembling magpie feathers. Gills are crowded, free, turning from white to grey and eventually melting into a black liquid (deliquescence). Stem is long, slender, white, and hollow, often with a slightly bulbous base and fibrous texture. Spore print is black.

Habitat & Growing Conditions

Typically grows solitarily or in small groups on the ground in deciduous woodlands, particularly under beech trees. It favors chalky or alkaline soils rich in leaf litter.

Season & Fruiting Time

Late summer to late autumn, usually appearing after periods of heavy rain.

Similar Looking Species

Coprinopsis atramentaria (Common Inkcap) which lacks the large white patches; Coprinus comatus (Shaggy Mane) which has a more cylindrical cap and shaggy, upturned scales rather than patches.

Ecological Role

Saprophytic; it plays an important role in the ecosystem by breaking down organic matter, specifically leaf litter and woody debris, returning nutrients to the soil.

Safety reminder

AI mushroom identification is a best-effort estimate and can be wrong. Never use it to decide whether a mushroom is safe to handle or eat — always confirm with a qualified mycologist before any consumption.
