Sampling was carried out from the regions with varying climates, forests types and altitudes. During this study, 228 specimens were collected and identified using morphological and molecular techniques, comprising 101 different species of gasteroid fungi belonging to 20 genera, 9 families and 5 orders. Among these, fifty taxa (50) seem previously undescribed and twenty four (24) are new records for Pakistan. Total gasteroid fungal taxa of order Agaricales studied in this investigation are seventy (70) represented by three families, i.e. Agaricaceae, Nidulariaceae and Phellorineaceae. Out of these, thirty eight (38) taxa seem new to science (17 of Lycoperdon, 15 of Bovista, 3 of Calvatia, 1 of Arachnion, Cyathus, and Tulostoma each) and sixteen (16) are first time reported from Pakistan. Agaricaceae includes one (1) species of Arachnion (A. olivoflavus), one (1) species of Battarrea (B. phalloides), twenty four (25) of Bovista (B. aestivalis, B. ahmadii nom. prov., B. areolata nom. prov., B. ayubiensis nom. prov., B. brunnescenta nom. prov., B. bovistoides, B. concinna, B. flavescens nom. prov., B. flavum nom. prov., B. fusca, B. himalaica, B. kreiselli nom. prov., B. lahorensis nom. prov., B. levisspora nom. prov., B. longispora, B. minima nom. prov., B. nigrescens var. rectapedicellata nom. prov., B. oblongispora, B. pakistanica nom. prov., B. pesudonigrescens nom. prov., B. plumbea, B. promontori, B. trachyspora and B. viridispora nom. prov., Bovista sp. (BPK92), four (4) of Calvatia (C. cyathiformis var. fragilis nom. prov., C. desosaiensis nom. prov., C. lilacina, C. pseudocyathiformis nom. prov.), 1 of Disciseda (D. hyalothrix), twenty eight (28) of Lycoperdon (L. albiceratum nom. prov., L. altimontanum, L. aurea-bruneum nom. prov., L. curtisii var. ovalisporum nom. prov., L. dermoxanthum var. album nom. prov., L. dermoxanthum var. flavum., L. excipuliforme, L. gilgitii nom. prov., L. japonicum, L. lahorense nom. prov., L. lahorense var. parvasporum nom. prov., L. lignum-bruneum nom. prov., L. lineum nom. prov., L. mammiforme, L. mammiforme var. magnasporum, L. molle, L. nigrescens, L. niveum, L. olivoflavum nom. prov., L. parvasporum nom. prov., L. perlatum, L. pratense var. flavum nom. prov., L. pseudoniveum nom. prov., L. pyriforme, L. sharanense nom. prov., L. sclerocystis nom. prov., L. utriforme, and Lycoperdon sp. (LPK74), one (1) of Montagnea (M. arenarea), 1 of Podaxis (P. pistillaris), five (5) of ii Tulostoma (T. fimbriatum, T. morenoii nom. prov., T. squamosum, Tulostoma sp. 1 (TPK6), Tulostoma sp. 2 (TPK4). Nidulariaceae includes two (2) of Cyathus (C. olla, C. pakistanicus nom. prov.), and Phellorineaceae includes one (1) species of Phellorinia (P. herculeana). Gasteroid fungal taxa of order Boletales are thirteen (13) belonging to three families, i.e. Diplocystaceae, Rhizopogonaceae, and Sclerodermataceae. Among these, three (3) taxa seem new to science (2 of Rhizopogon and 1 of Pisolithus) and five (5) are new records from Pakistan. Diplocystaceae includes one (1) species of Astraeus (A. hygrometricus). Rhizopogonaceae includes three (3) species of Rhizopogon (R. flavescens nom. prov., R. himalayensis nom. prov., R. roseolus). Sclerodermataceae includes six (6) species of Scleroderma (S. areolatum, S. bovista, S. chevelerii, S. dictyosporum, S. fuscum, Scleroderma sp. SPK21), 3 species of Pisolithus (P. flavescens, P. tinctorious, Pisolithus sp. PPK16). Among twelve (12) gasteroid taxa of geastrales belong to one family, geastraceae which includes ten (10) species of Geastrum (G. fimbriatum, G. himlayensis nom. prov., G. lycogalopsus nom. prov., G. pakistanicus nom. prov., G. parvulus nom. prov., G. patulus nom. prov., G. pseudolimbatum, G. pseudosaccatum nom. prov., P. saccatum, G. triplex), one (1) of Myriostoma (M. coliforme), one (1) of Radiigera (R. ayubiensis nom. prov.). In this family, seven (7) species are presented here as new and one (1) taxon is first time being reported from Pakistan. Phallales is represented by phallaceae in this study. It includes five (5) species of Phallus (P. ahmadii nom. prov., P. galericulatus, P. hadriani, P. roseus, and P. rubicundus). Among these, one (1) is proposed as a new species, and two (2) are new records for Pakistan. One sequestrate fungus Russula i.e. R. pakistanica nom. prov., belonging to Russulaceae of Russulales is also included in this study and seems previously undescribed. Some gasteroid specimens were taken as a loan from LAH herbarium, Pakistan, morphological descriptions of which are given at the end. iii Taxonomy is correlated with phylogenetic analysis of each genus based on ITS-nr- DNA region. Diversity of gasteroid species studied in different forests is also given. During this investigation, maximum diversity of gasteroid species was found in Himalayan moist temperate forests. Published work during this investigation has been appended as Annexure. iv ACKNOWLEDGEMENTS I would like to pay my heartiest gratitude to my respected teacher and PhD supervisor, Dr. Abdul Nasir Khalid for his continuous guidance, support, kindness and advices throughout the duration of my research work.
