A new species of Lecidella (Lecanorales, Ascomycota) from Azad Jammu and Kashmir, Pakistan

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

The newly described species, Lecidella iqbalii sp. nov., is so far only known from Azad Jammu and Kashmir, Pakistan. A comparative morpho-anatomical study combined with a phylogenetic analysis based on the marker ITS placed this species together with two accessions from southern South America in a distinct and highly supported group at the base of the Lecidella stigmatea clade. The taxon is characterized by a shiny thallus, strongly convex apothecia, a thin excipulum, a dark brown epihymenium and relatively small ascospores (10-) 11-12 (-13) × (6-) 6.5-8(-9) µm.
