Description
Summary:Toninia pakistanica sp. nov. is described from Darel Valley, Gilgit Baltistan, Pakistan. Its place within the genus Toninia A. Massal. was validated by a comparative morpho-anatomical investigation and ITS based molecular studies. The taxon is characterized by dark brown lobate squamules, epruinose to weakly pruinose with dark olive to black thallus, densely pruinose upper surface, more thicker epinecral layer 60 µm, 25–45 µm thick grey to blackish grey lower cortex and with the absence of apothecia and secondary metabolites. Its positioning in a separate branch in the phylogenetic tree also makes it distinct from the other known species. Phylogenetic analysis based on ITS-nrDNA sequencing placed our species relative to Toninia cinereovirens (Schaer.) A. Massal. Kiliasia nordlandica (Th. Fr.) Kistenich, Timdal, Bendiksby & S. Ekman is included and reported as new record to Pakistan.
