How to identify White Dapperling

To correctly identify White Dapperling (Leucocoprinus cretaceus), 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 2-6 cm in diameter, initially ovoid or bell-shaped, expanding to convex or plano-convex with a slightly depressed center. The surface is dry, chalk-white, and covered with fine, granular or mealy scales, especially towards the center. The margin is often striate and can be slightly upturned with age.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills are free from the stem, crowded, and white, sometimes developing a slight cream tint with age. They are relatively broad.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is 3-8 cm long and 0.3-0.8 cm thick, cylindrical, hollow, and fragile. It is white, often with a slightly granular or mealy surface, especially below the ring. A prominent, white, membranous, and movable ring is present on the upper part of the stem, which may sometimes disappear with age.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is thin, white, and fragile, with no significant odor or taste.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body is entirely white, becoming slightly cream-colored with age, and has a delicate structure.

6. 6

   Habitat

   Where it grows and on what substrate.

   Saprobic, growing solitarily or in small groups on rich, disturbed soil, compost, wood chips, leaf litter, and often in potted plants, greenhouses, and gardens. It is a common indoor mushroom.
