Amanita ravenelii
The whitish fruit bodies are medium to large, with caps up to 17 centimetres (6+1⁄2 inches) wide, and stems up to 25 cm (10 in) long.It is widely distributed in mixed and deciduous forests of the southeastern United States, where it grows solitarily or in groups on the ground in late summer and autumn.[4] Other North American species in the section Lepidella include A. abrupta, A. atkinsoniana, A. chlorinosma, A. cokeri, A. daucipes, A. mutabilis, A. onusta, A. pelioma, A. polypyramis, and A. rhopalopus.The universal veil remains as a pale yellow to brownish-orange layer that breaks up into crowded, rather coarse, conical to truncate-conical warts.The mushroom A. polypyramis is pure white, and lacks the pale yellow to brownish-orange large conical warts typical of A. ravenelii.[5] The North American species A. armillariiformis has a similar areolate cap surface, but unlike A. ravenelii, does not have a distinct basal bulb, and it is found in semi-arid areas associated with aspen and old growth Douglas fir.
