How to identify Lingzhi

To correctly identify Lingzhi (Ganoderma lingzhi), 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 kidney-shaped or fan-shaped, with a shiny, varnished appearance. The color ranges from reddish-brown to dark brown, often with concentric zones of different colors.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   N/A (Polypore - has pores instead of gills)

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is often lateral and may be absent in some specimens. It is typically varnished and has a similar color to the cap.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is tough and corky, with a bitter taste.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body is typically shelf-like and can grow up to 20 cm or more in diameter. It has a distinctive varnished appearance.

6. 6

   Habitat

   Where it grows and on what substrate.

   Grows on decaying hardwood logs and stumps.
