How to identify Parasol

To correctly identify Parasol (Parasola plicatilis), 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.

   Initially oval, expanding to convex or flat with radial grooves. Color ranges from tan to grayish-brown, fading as it dries. Diameter typically 1-4 cm.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   Free, closely spaced, and deliquescing (dissolving into a black, inky liquid) as they mature.

3. 3

   Stem

   Length, shape, surface, and any ring.

   Thin, hollow, and fragile. White to pale brown in color, smooth. Typically 3-8 cm long and 1-2 mm thick.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   Thin and fragile.

5. 5

   Fruiting body

   Overall growth pattern.

   Small and delicate, typically appearing after rain.

6. 6

   Habitat

   Where it grows and on what substrate.

   Grows in grassy areas, lawns, and meadows. Often found after rainfall. Saprobic, feeding on decaying organic matter.
