Amanita indogrisea, a new species of Amanita subg. Amanitina sect. Roanokenses from India

Abstract

Amanita indogrisea is described here as a new species from coniferous forests in the Union Territory of Jammu and Kashmir, India based on morpho-anatomy and molecular data. This species is characterized by its small to medium-sized basidiomata, ash grey to lilac-grey pileal surface with ash grey to greyish brown pulverulent-floccose to felted veil remnants, ash grey to greyish-white stipes with ovoid to ellipsoid basal bulb, ellipsoid to elongated basidiospores (10.5–15.0 × 7.0–10.0 μm) and the absence of clamps in all tissues. Molecular phylogenetic analysis based on nuclear ribosomal large subunit (nrLSU) sequences confirmed its identity as a new species nested within A. subgen. Amanitina sect. Roanokenses. Description of the new species is provided in this study.
