How to identify Panther Cap

To correctly identify Panther Cap (Amanita pantherina), 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 5-15 cm in diameter, brown to tan in color, and covered with numerous white, cottony warts. The cap is initially convex, becoming flattened with age. The margin is striate (grooved).

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills are free, crowded, and white.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is 5-15 cm long and 1-2 cm thick, white, and has a bulbous base. It features a ring (annulus) that is often fragile and may disappear with age. The base of the stem has a distinct, collar-like volva.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is white and does not change color when bruised.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body of Amanita pantherina is a mushroom with a cap and a stem.

6. 6

   Habitat

   Where it grows and on what substrate.

   Amanita pantherina is found in both deciduous and coniferous forests, often near oak and pine trees. It typically fruits in late summer and autumn.
