How to identify Rooting shank

To correctly identify Rooting shank (Xerula radicata), 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 3-8 cm in diameter, convex to flattened, and often has a broad umbo (a central raised area). The surface is slimy when moist and varies in color from yellowish-brown to tan.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills are white, widely spaced, and free to adnexed (narrowly attached) to the stem.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is long and slender, typically 8-20 cm long, with a distinctive rooting base that extends deep into the substrate.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is white and thin.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body consists of a cap and a long, slender stem with a distinctive rooting base.

6. 6

   Habitat

   Where it grows and on what substrate.

   Found in deciduous woods, often near decaying wood or tree roots.
