 1. Amanita cornelii, holotype, Baniyakund, Rudriprayag Distr., Uttarakhand, India. (CAL 1337) |
| intro | The brief description of this mushroom is based on its original description. |
| cap | The cap of Amanita cornelii expands to nearly flat with a distinct central umbo. The umbo is orangish brown. The remainder of the cap is mottled with brown and pallid radially-oriented patches and streaks. the margin of the cap is grooved with brown between the grooves. The volva is lacking from the cap in known material. |
| stem | The stem has a pallid ground color with nearly black fibrils stretched by expansion into a flame-like or zebroid pattern. The stem has no skirt or ring. At the stem's base is a white, membranous, sack-like volva. |
| odor/taste | Odor and taste of this species have not been reported. |
| spores | The spores of A. cornelii measure (8-) 9 - 11.5 (-13.5) 9 (7.5-) 8 – 10.5 (-13) μm, and are inamyloid and globose to subglobose (rarely broadly ellipsoid). Clamps are not present at bases of basidia. |
| discussion |
At present this species is only known from the state
of Uttarakhand, India. The two collections
were collected under Oak (Quercus) in a
forest dominated by Fir (Abies) and Oak. The pigment pattern on the cap is unusual in section Vaginatae and resembles pigment patterns on caps of other Amanita species including A. yuaniana (section Caesareae) and the amatoxin-containing A. marmorata and other taxa in section Phalloideae. The cap's pattern should not be used for definitive identification of this species—especially when collecting mushrooms for food—R. E. Tulloss |
