Amanita tullossiana, a new species, and two new records of Amanita section Lepidella from north-western Himalaya, India

摘要

Amanita tullossiana, a new species of Amanita [subgenus Lepidella] section Lepidella from India is described. The species is characterised by its ash grey to brownish-grey pileus covered with dark grey to greyish-black universal veil remnants, the upper part of its rooting stipe base covered by several rows of recurved scales, broadly ellipsoid to ellipsoid basidiospores, absence of basidial clamp connections and pileal remnants of universal veil comprising abundant, disordered inflated cells intermixed with scattered filamentous hyphae. Molecular phylogenetic analysis and morphology both support the association of A. tullossiana with species of Bas’ stirps Cinereoconia – A. cinereoconia and A. griseoverrucosa. Two species, A. griseoverrucosa and A. virgineoides are reported here as new records for India.
