How to identify Glistening Inkcap

To correctly identify Glistening Inkcap (Coprinellus micaceus), check each of these features in order. Misidentification is the most common cause of mushroom poisoning, so cross-reference multiple sources.

Step-by-step identification

1. 1

   Cap

   Shape, color, surface texture, and diameter.

   The cap is small, typically 1-3 cm in diameter, bell-shaped, and covered with glistening, mica-like particles when young. The color ranges from tan to ochraceous, fading to gray as it matures. The cap margin is often striate.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills are crowded, free, and white when young, turning black as they mature and deliquesce.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is slender, hollow, and white, typically 3-7 cm long and 2-4 mm thick. It is fragile and lacks a ring or volva.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is thin and fragile, with a pale color.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body is small and fragile, initially bell-shaped, becoming more convex with age. It deliquesces quickly.

6. 6

   Habitat

   Where it grows and on what substrate.

   Grows in clusters on decaying wood, often near stumps or buried roots, in urban areas, gardens, and parks. It is commonly found after rain.
