Abstract


Conocybe telasar sp. nov. was identified as a distinct species of Conocybe from various locations in district Mansehra, including Telasar, Oghi, Sumb, Balakot, and Attar Sheesha. The novelty of this taxon was established based on morpho-anatomical characteristics and molecular phylogeny of the ITS region, in comparison with already described species retrieved from GenBank. Phylogenetic analysis revealed that our species formed a clade closely related to Conocybe fuscimarginata (JX968238) and C. velutipes (JX968233). It is distinguished from allied species by several morphological features, such as creamy white basidiomata with central discoloration, white stipe arising from non-fragile ground grassland habitat, smooth pileus lacking dust and hairs, and ovate-elliptical spores measuring 7.5-10 × 4-6 µm. Microscopic observations showed cheilocystidia measuring 20-33 × 6.2-8.9 µm, while pleurocystidia were absent. Both morpho-anatomical and molecular evidence support the novelty of this species. Detailed descriptions and comparisons with allied taxa are provided in the results section.
