Amanita amplivelata, , (Amanitaceae, Agaricales), a remarkable new Eurasian species of the section Vaginatae

Abstract

Amanita amplivelata is introduced as a new species, based on numerous collections from geographically distant areas of Europe and the Near East (Bulgaria, the Czech Republic, France and T & uuml;rkiye). This new species is likely ectomycorrhizal with Populus spp. . in natural poplar stands, urban settings, and plantations. Detailed description and illustrations of its morphological features are presented. Phylogenetic analysis of nrITS and combined nrITS, nrLSU and TEF-1 alpha sequences placed it in a separate stirp in Clade 5 of section Vaginatae. . The ample, saccate volva with a peculiar microscopic architecture confirms relatively close phylogenetic relationships withA. A. crocea andA. A. dryophila. . The distinction of the new species from other phylogenetically related or morphologically similar taxa is outlined.
