A new species and a new record of the genus Candelariella (Candelariaceae, lichenized Ascomycota) from Pakistan

Candelariella darelensis sp. nov. is described from Darel Valley, Gilgit Baltistan, Pakistan, an area with a cold semi-arid climate. Its placement within the genus Candelariella M & uuml;ll.Arg. was validated by a comparative morpho-anatomical investigation and an analysis of ITS sequences. Candelariella darelensis sp. nov. is closely related to C. rosulans (M & uuml;ll.Arg.) Zahlbr. and characterized by crenulate, subsquamulose thallus areoles with 0.4-0.7 mm wide lobes, 1-1.5 mm wide apothecia with plane to convex disc, 65-145 mu m high hymenium, and asci with 8 ascospores of 12- 15 x 2.5-3.5 mu m. It grows on calcareous sedimentary rocks. In addition, C. xanthostigmoides (M & uuml;ll. Arg.) R.W. Rogers is reported as new to Pakistan.
