Parasola\ is a genus of small, veil-less coprinoid mushrooms in the family\ Psathyrellaceae\ (Agaricales). The genus is not well documented in Asia, specifically in Pakistan. In this study we describe two new species\ Parasola\ glabra\ and\ P.\ pseudolactea\ from Pakistan, based on morphological and molecular data. Phylogeny based on three DNA regions: nuc rDNA region encompassing the internal transcribed spacers 1 and 2 along with the 5.8S rDNA (ITS), nuc 28S rDNA D1-D2 domains (28S) and translation elongation factor 1α\ gene (TEF1α) show that the new taxa are clustered in a clade formed by the members of section\ Parasola\ of genus\ Parasola.\ Parasola\ glabra\ with grayish pileus, slightly depressed pileal disc, lamellae separated from the stipe by pseudocollarium, basidiospores 14.5{\textendash}16.5 {\texttimes} 9.5{\textendash}11.5 {\texttimes} 8.0{\textendash}10.5 {\textmu}m, in front view broadly ovoid to oblong, some with rhomboidal outline, in side view ellipsoid, with eccentric germ-pore of 1.5 {\textmu}m diameter.\ Parasola\ pseudolactea\ with yellowish brown to dull brown pileus, disc indistinctly umbonate, lamellae free, pseudocollarium absent, basidiospores 13.5{\textendash}14.5 {\texttimes} 10.5{\textendash}12.0 {\texttimes} 9.5{\textendash}10.5 {\textmu}m, in face view rounded triangular to heart shaped, rarely ovoid to subglobose, in side view ellipsoid to oblong, with eccentric germ-pore of 1.5 {\textmu}m diam. In addition to these new species,\ P.\ auricoma\ and\ P.lilatincta\ were also studied. Morphological descriptions for the new species and comparison with known\ Parasola\ species are provided. Our observations highlight the diversity of\ Parasola\ in northern Pakistan and further document the need for additional systematic focus on the region{\textquoteright}s fungi.
