Description
Summary:Many species of sect. (Fr.) Quél. cause death of people after consumption around the world. , a new species of sect. from Benin, is described here. The taxon represents the first lethal species of sect. known from Benin. Morphology and molecular phylogenetic analyses based on five genes (ITS, nrLSU, , α, and β ) revealed that is a distinct species. The species is characterized by its smooth, white pileus sometimes covered by a patchy volval remnant, a bulbous stipe with a white limbate volva, broadly ellipsoid to ellipsoid, amyloid basidiospores, and abundant inflated cells in the volva. Screening for the most notorious toxins by liquid chromatography-high-resolution mass spectrometry revealed the presence of α-amanitin, β-amanitin, and phallacidin in .
