Abstract
Amanitatullossiana, 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.
Highlights
The Amanitaceae is one of the most dominant and species-rich families of Basidiomycota
NrLSU sequences were used in this study to delimit the Indian Amanita species
The rpb2 sequences were not used for reconstruction of molecular phylogeny because rpb2 sequences for most of the Amanita species are currently unavailable in GenBank for inclusion in this study
Summary
The Amanitaceae is one of the most dominant and species-rich families of Basidiomycota. Distinct from all the known species of Amanita stirps Cinereoconia by the combination of the following characters: medium-sized to large basidiomata (pileus 90–170 mm wide, stipe 150–185 × 20–25 mm); brownish-grey to dark grey pileus covered with floccose to subfelted, pulverulent patches of universal veil remnants; broadly ellipsoid to ellipsoid basidiospores measuring (8.5–)9–13(–13.5) × (5.8–)6–8(–8.5) μm.
