Amanita angelica, ITS dataset and ML tree

This study describes a new species in Amanita sect. Caesareae from oak habitats throughout much of the southeastern United States. Amanita angelica sp. nov. is distinguished morphologically from others in the section by the combination of the scarlet red pileus that fades to tawny at the center and light yellow towards the margin, the light cream-colored lamellae (not yellow), the yellow annulus and white to yellowish tinged stipe, and the white volva that becomes noticeably gray in patchy areas. An ITS phylogeny supports the unique phylogenetic placement of A. angelica where it is nested in a strongly supported clade including at least 10 other species of Amanita sect. Caesareae. The phylogeny supports the distinction of A. angelica apart from other named eastern North American species such as A. arkansana and A. jacksonii.
