摘要

The genus Amanita is a well-known, large monophyletic genus of fungi with a wide distribution; the species of which are of great ecological importance due to their ectomycorrhizal status. However, the diversity of Amanita species in Russia has been underestimated. Here, we describe three new species of Amanita (A. firma, A. quasibattarrae, and A. recondita) from the Far East territory based on morphological and phylogenetic evidence. To determine the taxonomic status and phylogenetic position of the studied species multi-locus phylogenetic trees of Amanita subg. Amanita sect. Vaginatae subg. and Amanitina sect. Amidella are inferred based on the internal transcribed spacer region (nrITS), large subunit nuclear ribosomal RNA gene (nrLSU), and the translation elongation factor 1-alpha (TEF1-α). The detailed descriptions and illustrations of the novel taxa are provided with the comparisons to closely related species.
