Amanita frostiana
Roger Heim reported A. frostiana as occurring in Thailand,[7] but this was probably a misidentification of A. rubrovolvata.A. subfrostiana, also referred to as 'False Frost's Amanita', has the same natural habitat as of A. frostiana, but is mostly distributed in southwestern China.The distinct and starkly white bulb (e.g., 17 x 15 mm) bears a white or yellow-white collar that is somewhat similar to the collar seen in the exannulate A. albocreata,[1] which is a species of the hardwood-hemlock (Tsuga) forest of the northeastern U.S. and southeastern Canada and of boreal forest at least as far north as the Island of Newfoundland.The clamps present at bases of basidia of this species specially support the presumed relationship to A. muscaria var.Many misidentifications have taken place while recognizing A. flavoconia, one of the most common and widespread species of Amanita in eastern North America, due to various similar physical characteristics.
