Two new species of Entoloma subgenus Cyanula (E. alpigenum and E. muscicola) from montane forests of Azad Jammu and Kashmir, Pakistan (Agaricales, Entolomataceae)

Two new species of genus Entoloma in subgenus Cyanula, Entoloma alpigenum and Entoloma muscicola are described from the mixed forests of Azad Jammu and Kashmir, Pakistan. Entoloma muscicola is characterized by a cuspidate, deep brown pileus with wavy margins, distant pale yellow lamellae, weakly angled mono-gutulate basidiospores, predominantly two-spored basidia, and clavate cheilocystidia with wavy apical caps. In contrast, Entoloma alpigenum is characterized by a light brown, slightly squamulose pileus, pale yellowish lamellae, larger 5–7 angled mono-gutulate basidiospores and cylindrical to flexuose cheilocystidia.

Both species are ecologically associated with high-altitude mixed forests. Phylogenetic analyses have placed these new species in subgenus Cyanula, forming sister clades within section Griseocyanea, which support their distinct taxonomic status. Illustrated descriptions of their macro- and microscopic features and phylogenetic analyses, based on nrITS, nrLSU, mtSSU and rpb 2 regions are provided.
