Coprinus comatus, commonly known as the Shaggy Ink Cap, Lawyer's Wig, or Shaggy Mane, is a distinctive and easily recognizable mushroom. It is characterized by its cylindrical, white cap covered in shaggy scales, which gradually deliquesces (self-digests) into a black, inky fluid as it matures. This mushroom is found in grassy areas, lawns, and disturbed ground, often appearing in groups. Young specimens are edible and considered choice, but they must be consumed shortly after harvesting due to their rapid deliquescence. As the mushroom ages, it turns black and becomes inedible.
How to Identify
- Cap
- The cap is cylindrical to oval, typically 5-20 cm in height and 2-5 cm in diameter. It is white when young and covered with shaggy, upturned scales, giving it a distinctive appearance. As the mushroom matures, the cap edges begin to turn black and dissolve into an inky liquid, a process known as deliquescence.
- Gills
- The gills are crowded, free from the stem, and white when young. As the mushroom matures, the gills turn pink, then black, and eventually dissolve into an inky fluid, starting from the bottom edge of the cap and moving upwards.
- Stem
- The stem is typically 5-20 cm long and 1-2 cm thick, white, hollow, and smooth. It is often slightly enlarged at the base. A fragile, movable ring may be present on the stem, but it often disappears as the mushroom matures.
- Flesh
- The flesh is white and thin. It is relatively soft when young but quickly deteriorates as the mushroom ages and deliquesces.
- Fruiting body
- The fruiting body of Coprinus comatus is initially cylindrical and elongated, resembling a closed umbrella. As it matures, the cap expands slightly but retains its cylindrical shape. The entire mushroom is typically white when young, with a shaggy or scaly texture on the cap surface.
- Habitat
- Coprinus comatus is commonly found in grassy areas, lawns, parks, and disturbed ground. It often grows in groups or clusters and can appear in both urban and rural environments. It is frequently seen along roadsides and in areas with rich soil.

Safe
SafeCoprinus comatus is generally considered edible when young and before deliquescence begins. However, it is crucial to avoid consuming it with alcohol, as some related species (e.g., Coprinopsis atramentaria) contain coprine, which can cause an Antabuse-like reaction when combined with alcohol.

Finding Tips
Look After Rain
Shaggy Ink Caps often appear after periods of rain, as moisture promotes their growth.
Check Grassy Areas
Focus your search on grassy areas, especially those that are well-fertilized or have rich soil.
Morning Search
Search in the morning, as the mushrooms deliquesce quickly and may disappear by the afternoon.
