How to identify Common Bonnet

To correctly identify Common Bonnet (Mycena galericulata), 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 typically 1–2 cm (3⁄8–3⁄4 in) in diameter, and is conical to convex in shape. The cap surface is smooth and dry, and is typically pale brown to greyish-brown in color. The cap margin is typically incurved when young, and becomes straight to uplifted with age.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills of Mycena galericulata are adnate to decurrent, meaning that they are attached to the stem and run down it slightly. The gills are typically pale brown to greyish-brown in color, and are closely spaced.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is typically 3–6 cm (1 1⁄8–2 3⁄8 in) long and thin, with a hollow interior. The stem surface is smooth and dry, and is typically pale brown to greyish-brown in color. The stem base is typically slightly enlarged.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh of Mycena galericulata is thin and fragile. It is typically pale brown to greyish-brown in color.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruit body of Mycena galericulata is a small mushroom with a cap and a stem. The cap is typically 1–2 cm (3⁄8–3⁄4 in) in diameter, and is conical to convex in shape. The cap surface is smooth and dry, and is typically pale brown to greyish-brown in color. The stem is typically 3–6 cm (1 1⁄8–2 3⁄8 in) long and thin, with a hollow interior. The stem surface is smooth and dry, and is typically pale brown to greyish-brown in color.

6. 6

   Habitat

   Where it grows and on what substrate.

   Mycena galericulata is a saprotroph, meaning that it obtains nutrients from dead organic matter. It is typically found in deciduous woods on fallen twigs and woody debris. It is a common species, and can be found throughout the world.
