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

Abstract

A new species from coniferous forests in Pakistan, Amanitaahmadii, is described on the basis of morpho-anatomy and molecular data set analyses. This species is characterized by its medium-sized to large basidiomata, 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 basidiospores, 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. Amanitinasect.Validae.

“…Amanita is the largest genus; it harbors 95% of the species in the family and includes more than 600 accepted species (Kirk et al 2008;Cui et al 2018). Many species of Amanitaceae have been extensively collected and studied since the 1990s in China, and there are more than 200 formally described taxa (Yang 1997(Yang , 2005(Yang , 2015Zhang et al 2010;Deng et al 2014;Deng et al 2016;Li and Cai 2014;Ariyawansa et al 2015;Li et al 2015;Cai et al 2016;Liu et al 2017;Cui et al 2018;Jabeen et al 2019;Ullah et al 2019;Saba et al 2019;Zhang et al 2020).…”
