How to identify Plums and Custard

To correctly identify Plums and Custard (Tricholomopsis rutilans), 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 convex to flattened, measuring 4-10 cm in diameter. It is characteristically yellow with purplish-red to reddish-brown scales or fibrils. The margin is often incurved when young.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills are adnate to slightly decurrent, closely spaced, and yellow. They may have a slightly serrated edge.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is 4-8 cm long and 1-2 cm thick, yellowish, and covered with reddish-brown fibrils or scales. It is typically solid and may be slightly club-shaped.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is yellowish, relatively thin, and has a slightly bitter taste.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body is medium-sized, with a colorful cap and a central stem. The overall appearance is quite distinctive due to the contrasting colors.

6. 6

   Habitat

   Where it grows and on what substrate.

   Grows on decaying conifer wood, such as logs and stumps, in coniferous forests.
