Auritella foveata, a new species of Inocybaceae (Agaricales) from tropical India

Auritella foveata C. K. Pradeep & Matheny is described as new from mixed evergreen forests in tropical India. The species is distinctive due to the combination of a pitted-rugulose pileus, smooth subglobose spores, and chains of elongated thick-walled cheilocystidia. The latter two traits characterise the tropical African species A. aureoplumosa (Watling) Matheny & Bougher. Phylogenetic analysis of a supermatrix of rpb1, rpb2, and nLSU-rRNA gene regions supports the placement of A. foveata as sister to the remaining species of Auritella, a genus with a paleotropical and southern hemisphere distribution. A key to all eight species of the genus is provided together with illustrations of the new species.
