How to identify Shiitake

To correctly identify Shiitake (Lentinus edodes), 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 of a shiitake mushroom is typically 5-15 cm in diameter. It is brown to dark brown in color and has a smooth or slightly scaly surface. The cap is often slightly convex, but it can flatten out as it ages.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills of a shiitake mushroom are white to pale brown in color and are attached to the stem. They are closely spaced and often have a slightly toothed edge.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem of a shiitake mushroom is typically 2-5 cm long and 1-2 cm thick. It is white to pale brown in color and is usually attached to the cap in the center. The stem is often slightly hairy or scaly.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh of a shiitake mushroom is white and firm.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body of a shiitake mushroom is typically 5-15 cm in diameter and has a characteristic umbrella-shaped cap.

6. 6

   Habitat

   Where it grows and on what substrate.

   Shiitake mushrooms are saprophytic and grow on dead or decaying hardwood trees. They are often found in forests or on logs.
