Amanita vernicoccora sp. nov. —the vernal fruiting 'coccora' from California
We describe Amanita vernicoccora, a vernal fruiting species known as the "spring coccora" in California. Sequence analyses of four DNA regions and phenotypic traits demonstrate that A. vernicoccora, long considered a pale-colored form of the autumnal fruiting A. calyptroderma (the 'fall coccora'), is a unique species. Morphological and genetic data support both species in section Caesareae. We also address some nomenclatural and taxonomic intricacies surrounding application of the proper name for the fall-fruiting coccora.
