Inocybe quercicola sp. nov. (Agaricales, Inocybaceae), from Pakistan

Abstract

The new species Inocybe quercicola is described on the basis of morphological and genetic features. It is characterized by medium-sized basidiomata, radially fibrillose campanulate pileus, dark brown lamellae when mature, stipe that is pruinose along the whole length, nodulose, rather small basidiospores (av. 8.8×5.5 μm, Qav.=1.53) and pleurocystidia which are similar to cheilocystidia in shape but smaller in size (19–22 × 47–65 μm). Based on the phylogenetic analysis of nuclear ribosomal ITS and LSU nucleotide sequences I. quercicola belongs into I. sect. Marginatae, subsect. Praetervisae.
