ABSTRACT Diploschistes pakistanicus sp. nov. is described from the Himalayan moist temperate forest, Pakistan. ITS sequences confirm its position within the genus Diploschistes and, together with its morphology and chemistry, suggest that it is separate from other species of this genus. The taxon is characterized by grey to greyish white pruinose thallus, perithecioid-type ascomata, small apothecia 0.1‒0.4 mm wide, hypothecium 20‒25µm thick, ascus of 85‒110 × 9‒17 µm in size, 3‒5 transverse and 2‒4 longitudinal septa in large ascospores 42‒55 × 18‒30; also differing from related species in ITS region. sp nov forest Pakistan chemistry thallus perithecioidtype perithecioid type ascomata 0104 0 1 4 0.1‒0. wide 2025µm 20 25µm thick 85110 85 110 85‒11 917 9 17 9‒1 size 35 3 5 3‒ 24 2 2‒ 4255 42 55 42‒5 18‒30 1830 18 30 region 010 0.1‒0 8511 8 11 85‒1 91 9‒ 425 42‒ 18‒3 183 01 0.1‒ 851 85‒ 18‒ 0.1 0.

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.
