Title :A Survey of Amanita in Western Washington, U. S. A.
Authors :Nakamura, Naoshi
Issue Date :30-Jun-1970
Abstract :In this study, all Amanitas (nineteen species and three varieties) reported from the state of Washington are included, and are classified according to Singer's idea of the infrageneric taxonomy of the genus. Amanita fulva and A. livida are reported from Washington for the first time. A collection thought to be a new species is given a provisional name, Amanita pach ycolea Nakamura, nom. prov.. Amanita muscaria has been segregated into several color forms, of which var. muscaria (red form), var. formosa (yellow form), var. umbrina (brown form), and var. alba (white form) are recognized from Washington. Although they have been reported from Washington, the actual occurrence in the state of Amanita caesarea, A. phalloides, and A. citrina is doubtful. Amanita chlorinosma is treated as a synonym of A. solitaria, as the odor of chlorine is not necessarily limited to the former species. Amanita calyptrata, A. umbrinidisa, and A. praegemmata once reported from Washington are species of questionable validity, whose true status can be determined by further collection and study, including examination of the type.
