Amanita ahmadii, a new species of Amanita subgenus Amanitina section Validae from Pakistan

A new species from coniferous forests in Pakistan, Amanita ahmadii, is described on the basis of morpho-anatomy and molecular data set analyses. This species is characterized by its medium-sized to large basidi-omata, grayish brown to brown pileal surface and rimose pileus margin with gray to dark brown verrucose veil remnants, a cream stipe with bulbous base having grayish brown or brown longitudinal striations above the annulus, a scaly surface towards the base, globose to broadly ellipsoid and amyloid basidi-ospores, and the absence of clamped septa in all tissues. Molecular phylogenetic analyses based on ITS and LSU sequences confirmed its identity as a new taxon nested within subgen. Amanitina sect. Validae.
