Amanita griseofusca: A new species of Amanita in section Vaginatae from MalamJabba, Swat, Pakistan

Abstract:

 A new species, Amanita griseofusca  in section Vaginatae  is described and illustrated here from Pakistan. Distinguishing

characters of the new species include medium-sized basidiomata, greyish brown pileus surface with white to beige, membranous

volval remnants present as one (large) to a few (small) warts, close lamellae which are cream colored with a pink

tone, striations one third of the total pileus radius, broadly ellipsoidal to ellipsoidal basidiospores and white loose saccate

volva turning beige at maturity. Molecular data inferred from partial nuc rDNA internal transcribed spacer region (ITS),

partial nuc rDNA larger subunit region (LSU) and partial translation elongation factor 1-alpha (tef1) confirms the novelty

of the present taxon.
