Morphology, multilocus phylogeny, and toxin analysis reveal two new species of <i>Amanita</i> section <i>Amanita</i> (Amanitaceae) from China.

ABSTRACT: Globally, many species of Amanitasect.Amanita (Amanitaceae, Agaricales) cause poisoning after consumption. Amanitaflavomelleiceps sp. nov. and Amanitaparvisychnopyramis sp. nov., two new species of A.sectionAmanita from China, are described here. Morphology and molecular phylogenetic analyses based on five genes (ITS, nrLSU, RPB2, TEF1-α, and TUB2) revealed these two taxa as distinct species. Amanitaflavomelleiceps sp. nov. is characterized by a yellowish-to-yellow pileus covered by verrucose volval remnants; a subglobose basal bulb with shortly limbate; subglobose to broadly ellipsoid, inamyloid basidiospores. Amanitaparvisychnopyramis sp. nov. is characterized by a brownish pileus covered by subconical volval re
