Phylogenetic studies on the genus Candolleomyces (Psathyrellaceae, Basidiomycota) occurring in the bed of the Indus River, Punjab, Pakistan, reveal three new species.

ABSTRACT: During macrofungal surveys in 2019-2024, several specimens belonging to the family Psathyrellaceae were collected from the bed of the Indus River, Punjab, Pakistan. Phylogenetic analyses, based on ITS, LSU, and tef-1α sequences and morpho-anatomical study, confirmed the novelty and placement of three taxa in the genus Candolleomyces. They are described as Candolleomycescrenatus, C.undulatus, and C.virgatus. For distinguishing characters, C.crenatus has crenate cap margins, small basidiospores, and a marginate base of stipe. Candolleomycesundulatus has parabolic to campanulate, wavy margins, light purplish gray with a light brownish gray center of pileus, and an appendiculate, pendant annulus. Candolleomycesvirgatus has a parabolic to plane,
