How to identify Clustered Domecap

To correctly identify Clustered Domecap (Lyophyllum connatum), 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 4-10 cm in diameter, smooth, and can range in color from white to pale tan or grayish. It is often convex when young, flattening out with age.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills are crowded, adnate to slightly decurrent, and white to cream-colored. They may discolor slightly with age.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is typically 4-8 cm long and 1-2 cm thick, white to pale tan, and smooth. It is usually central and solid.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is white and firm, with a mild odor that can sometimes be slightly mealy or farinaceous.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body of Lyophyllum connatum typically forms in dense clusters. The mushrooms are medium-sized with a smooth, pale cap and a central stem.

6. 6

   Habitat

   Where it grows and on what substrate.

   Lyophyllum connatum is commonly found in grassy areas, meadows, and open woodlands. It often grows in clusters or fairy rings, typically in the fall.
