A new agaric species, Leucoagaricus thallensis, a member of La. sect. Leucoagaricus is described and illustrated from Pakistan. This species is mainly recognized by the combination of the orange-red fibrillose pileus with a white background, the fibrils on the stipe, and the volva. Data on macromorphology, micromorphology, DNA sequences (nrITS and nrLSU), habitat and comparison with closely related taxa are provided for each. Morphological and molecular phylogenetic differences separate our species from all other known species of Leucoagaricus proving its novelty. This study is the first contemporary taxonomic work on Leucoagaricus species from Noorpur Thal, district Khushab.

A new species belonging to the Rusticoides clade of Entoloma, with an omphalinoid habit is described from Pakistan with detailed morphological descriptions, illustrations and molecular data. Illustrations of microcharacteristics and comparison with closely allied species are provided. Entoloma griseofibrillosus is distinguished based on a greyish brown, hygrophanous fibrillose pileus, sub-isodiametric angular spores, varying shapes of cheilocystidia and a pileipellis as a cutis. Phylogenetic estimation based on nrITS and nrLSU regions with a well-nested position of the described taxon is presented in the current study.

During surveys of macrofungi in Pakistan, eight specimens belonging to the genus Lactocollybia were collected from the plains of Punjab and foothills of Murree. Morphological studies and molecular characterization refer all collections to a single species, Lactocollybia variicystis, previously restricted to Africa and Europe; this is the first report from Asia. Except for geography, no significant differences were found among African, European, and Pakistani collections.

Pluteus variabilicolor and Volvopluteus earlei are reported as new records for the Pakistani funga, with the former representing a new record for South Asia and the latter, a second report from Asia. Morphological descriptions are accompanied by colored photographs of basidiomata and microscopic structures. Identity of both species is confirmed by ITS sequence analyses. Comparison with previous descriptions and data on their distributions are briefly discussed.

Moniliophthora pakistanica sp. nov. is described from Punjab, Pakistan, based on micro- and morphological characteristics and phylogenetic analysis. The taxon is characterized by a creamy to brownish basidiomes, a depressed or subumbonate and tomentose pileus with distinct orange to brown zones, a hairy stipe, oblong to ellipsoid basidiospores (4.7–8.5 × 4–6 μm), frequent clavate to flexuous cheilo- and pleurocystidia with apical projections, common long setiform terminal hairs in both pileipellis and stipitipellis, rhizomophs, and growth on fallen plant debris. A detailed description of macro- and microscopic characters and field photographs of collections are given. Based on our phylogenetic analysis, M. iopus is found to be a close relative of the new species. Two phylograms inferred from the datasets of nrITS and nrLSU sequences, and a comparison with phylogenetically closely related species are provided.

In recent studies, new species and sections were described in Agaricus subg. Spissicaules. We intended to update this subgenus by including all these recent taxa, some interesting sequences retrieved in GenBank, and two new collections from the Punjab Province, Pakistan. Both morphological and phylogenetic approaches were used. Maximum Likelihood tree based on rDNA ITS sequences revealed that the sequences of the new specimens from Pakistan form a clade with five sequences from India retrieved from GenBank. For the seven samples of this clade, we described the new species Agaricus radiatosquamulosus based on the morphology of the two collections from Pakistan. This new species, which belongs to the recently proposed A. sect. Fulventes was compared to the three other species of this section. Except for the small-sized A. nanofulvus, the other species are difficult to recognize without DNA sequence data. The four species differ from each other at a poly T in ITS2. In addition, each of them is distributed on different continents. Agaricus radiatosquamulosus is the first report of a species of A. subg. Spissicaules in Pakistan. In addition, a sequence from GenBank identified as A. lanatoniger matches with another sample from New Zealand in A. sect. subrutilescentes. In absence of formally published taxonomic treatment, we provisionally named these samples A. cf. lanatoniger.
