Termitomyces pakistanensis sp. nov. is a member of an edible genus generally distributed in Asia and Europe. This species has been described as new species based on its different morphology, and scanning electron microscopy (SEM) of basidiospores. The novelty and degree of endemism is confirmed by analyzing the genetic variation of the internal transcribed spacer regions (ITS1–5.8 S–ITS2) of the ribosomal DNA gene, a universal fungal marker. The evolutionary affinities of new species is also evaluated with Asian and European species by phylogenetic analysis based on ITS sequences. In our phylogenetic analysis, this genus is found monophyletic comprising of two monophyletic sub clades: Clade I, Microcarpus, with small sized fruiting bodies generally less than 5 cm without pseudorrhiza and Clade II, Macrocarpus, with large sized fruiting bodies generally more than 5 cm having pseudorrhiza. All collections of Pakistani species clustered independently in Microcarpus clade showing their endemic genetic makeup as it is clustering independently. A comprehensive description, photographs of the basidiocarps and Scanning electron microscopy (SEM) micrographs of spores are provided. Research Highlights: It has a new species from Pakistan to world based on the scanning electron microscopy and further confirmed by DNA barcoding.The exact shape and size of basidiospores of this novel species is first time introduced by using SEM analysis.This genus is rarely described from Pakistan.This paper has introduced a two clade, Microcarpus and macrocarpus, in the world for this genus.

The current study investigates the total bacterial contamination in various packed and unpacked ras malai samples of 14 different localities of Lahore, Pakistan. The bacterial colonies such as Bacillus sp. and Gamella sp. were isolated from ras malai samples and grown on agar‐broth media under sterile environmental conditions. Serial dilution technique was used to compose the replicates to get a viable count of bacteria in the samples. Results indicated that in case of packed ras malai samples, maximum bacterial count was observed in Sample 1 (422 × 10−2 to 402 × 10−6) and minimum bacterial count was in Sample 4 (21 × 10−2 to 9.3 × 10−6). For unpacked ras malai samples, maximum bacterial count was in Sample 3 (200.3 × 10−2 to 181.3 × 10−6) and minimum bacterial count was observed in Sample 1 (110 × 10−2 to 90.4 × 10−6). It was concluded that the marketed samples contain more bacterial count as compared to the standard sterilization values. Such products could possibly become the cause of many health problems in children. [ABSTRACT FROM AUTHOR]

Himalayan range of Pakistan is one of the diversity rich hotspots of the world. Many areas are yet to be explored here to discover new species of organisms including fungi. During present research, Swat District of Pakistan was explored for fungal diversity. One new species of mushroom Russula swatica (Russulales) is described from Himalayan range of Pakistan and analyzed by light microscopy and scanning electron microscopy as well as by molecular markers. A comprehensive description, photographs, and comparisons with morphologically similar and phylogenetically related species are provided. Conclusions of its phylogenetic relationships within the genus are provided based on the sequence of the nuclear internal transcribed spacer region. [ABSTRACT FROM AUTHOR]

This study was carried out to identify 20 high valued medicinal plants of District Lahore, Punjab, Pakistan with the help of the palynological studies. The distinguishing characteristics for selected species were found by systematized methods using light microscopy and Scanning Electron Microscopy. In this study, important pollen qualitative and quantitative features of these medicinal species such as polar and equatorial outline and their diameter, P/E ratio, presence or absence of pore, sculpturing of pollen, exine thickness, intine thickness, intercellular distance of exine and intine, presence or absence of spines, length of spines, width of spines, presence or absence of colpi and length of colpi, were compared. Remarkable variations in these pollen characters have been observed. Pollen grains were usually circular‐semicircular (Calendula officinalis), spheroidal (Convolvulus arvensis), bilobed and trilobed (Convolvulus arvensis), spiny, (Abutilon indicum), oblate (Terminalia chebula) and elongated (Euphorbia pilulifera). In polar view Conyza bonariensis exhibited the highest pollen size [195.9 (211.6–180.2) μm]. While in equatorial view Calendula officinalis and Euphorbia pilulifera had lowest value [22.5 (20–25) μm] whereas Carissa carandas [165 (140–179) μm] appeared to be the largest. Parthenium hysterophorus showed the highest P/E ratio, that is, 1.28. Colpi were reported in only 7 species. Most of the plants showed 100% fertility but Terminalia chebula showed the least value 35%. In the present, project the diversity in pollen morphology present pollen as a valuable taxonomic tool. It is also concluded that pollen features are helpful at the specific level as well as generic level and can provide us fruitful taxonomic solutions. Research Highlights: Palynological flora of the medicinal plant species of district Lahore, Pakistan is investigated first time on the basis of LM and SEM and the flora is found very significant for taxonomic investigations.
