Amanita pantherina, also known as the Panther cap or Panther amanita, is a medium to large fleshy agaric with a brownish cap, pure white patches, white stem, ring, and bulbous base with distinct margin. It grows solitary or in small groups on soil under conifers or in mixed hardwood-conifer forests.

Cap initially domed and later flattens out, with a very finely striated margin. It is shiny brown or grey-brown and has densely distributed warts that are pure white to sordid cream in colour. These warts are minutely verruculose and can be easily removed. Gills free, close to crowded, white becoming greyish, truncate and fairly broad. Stem subcylindrical, white, becoming slightly tannish in age, stuffed then hollow, finely floccose becoming smooth above the white ring that is initially quite chunky but often becomes thin and floppy in more mature specimens, sometimes with a toothed edge. The stem tapers towards the apex and ends in a swollen basal bulb. Spore print white.

Microscopic Features: The spores are broadly ellipsoidal to ovoid in shape, with a smooth surface. They measure 8-12 µm in length and 6.7-7.5 µm in width. They are inamyloid.

Similar species include Amanita rubescens, which also can have a brownish cap but its stem and cap flesh turn pink or red when damaged.

Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we strongly advise against consuming wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.
