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.

ABSTRACT A new species in the genus Lobothallia (Megasporaceae, lichenized ascomycetes), from Margalla Hills, Pakistan, is described and illustrated here under the name Lobothallia densipruinosa. It is characterized by contiguous, clustered, densely pruinose dark olive apothecia, conidia 6-10 µm long, and large areoles and lobes. Phylogenetic analysis based on ITS-nrDNA sequencing placed our species relative to L. pruinosa. Descriptions and images of the new species are provided, as well as a key for the 21 species of Lobothallia known to the world.

ABSTRACT During our surveys of mushrooms in 2019 and 2020, an interesting species of the genus Lepiota was collected from three different areas of Punjab (Bahawalnagar, Sheikhupura, and Muzaffarghar), Pakistan. These areas vary in their altitude and somewhat climatic conditions, nevertheless, morpho-anatomical comparisons and molecular analyses proved that these collections represented the same taxon, described here as Lepiota brunneogranulosa. This new species is characterized by a pileus with a yellowish-brown central disc, with brown colored granules on a very pale brown background, dextrinoid, ellipsoid basidiospores, frequently bi-sporic basidia, and narrowly clavate cheilocystidia. Because of the hymeniform pileus covering, and the placement in the phylogeny, based on Internal Transcribed Spacer (nrITS) and Larger Subunit (LSU), it belongs to the Lepiota sect. Lilaceae.

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.
