A new Amanita from Chile

During our stay in the Nothofagus region near Osorno from April to July 1979, we collected an interesting species of Amanita, Unlike A. diemii Sing., which appeared to be rather common in this area, the new species was collected only once. Our Amanita is undoubtedly identical with A. gayana (Mont.) Mont., as described by Singer (1969: 151). However, checking the protologue of Agaricus gayanus Mont. (1853: 332), we soon discovered that we were dealing with two different species. Therefore we have to describe our (and Singer’s) species as a new one, naming it A. aurantiovelata.
