Pucciniastrum agrimoniae, Melampsora populina subsp. populina and Puccinia coronata var. himalensis are reported as new records for Sharan (Kaghan Valley). Agrimonia eupatoria, Populus alba and Sporobolus coromandelianus are reported as new host plants from Pakistan for Pucciniastrum agrimoniae, Melampsora populina subsp. populina and Puccinia coronata var. himalensis, respectively. Previously, about 93 species of rust fungi were known from Kaghan Valley with only 28 rust taxa from Sharan. This study has raised the number of reported rust taxa of Sharan to 32.

Based on morphological and molecular data, five new species are described: Leucoagaricus badius, L. lahorensiformis, L. pakistaniensis, L. sultanii, and L. umbonatus. Descriptions and illustrations are given for the new taxa. A phylogeny based on morphology and four DNA regions, including the internal transcribed spacers (ITS1-5.8S-ITS2 = ITS) and D1-D2 domains of the 28S gene of the nuc rDNA, the gene for RNA polymerase II second largest subunit (RPB2), and the translation elongation factor 1-α gene (TEF1-α), shows that the new taxa are clustered in a clade representing Leucoagaricus section Rubrotincti subgenus Sericeomyces.

Himalayas include more than hundred mountains exceeding 7,200 metres. The Himalayan region of Pakistan is recognized as the well known Western Himalayan Province famous for its unique endemic and threatened biodiversity,which gives it as a distinction viz Western Himalayan Moist Temperate Ecoregion in the Global-200 priority ecoregion for conservation. It hosts enormous tangible and intangible resources broadly recognized as socio-cultural, physical and biological resources. The Himalayas of Pakistan not only preserve the precious biodiversity but also provide precious ecosystem services including supporting, providing and cultural services. The Himalayan highlands of Pakistan provide uncountable environmental benefits and socioeconomic standing to the dwellers of the region.

È inoltre responsabile di gravi infezioni invasive (Invasive Pneumococcal Disease, IPD) quali batteriemia, polmonite e meningite, caratterizzate dall'elevata letalità. Tra gli aspetti che rendono le infezioni invasive particolarmente temibili vi è la crescente diffusione in tutto il mondo della multi-antibiotico-resistenza che rende difficile la terapia di queste malattie invasive (1). L'epidemiologia delle malattie da pneumococco è cambiata dopo l'introduzione dei programmi di vaccinazione pediatrica con il vaccino pneumococcico coniugato 7-valente (PCV7), nei primi anni 2000. In tutte le fasce di età è stata osservata una notevole riduzione dell'incidenza delle IPD causate dai sierotipi contenuti nel PCV7, sebbene la presenza di IPD provocate da ceppi non coperti dal PCV7 desti preoccupazione. Il peso epidemiologico più alto si trova ora negli anziani (2, 3). Nell'Unione Europea, si stima che ogni anno

In this study, four (04) plant taxa of Poaceae infected with rust fungi are collected from different wheat crops grown in different areas of Pakistan. The rust fungi are isolated, characterized and identified. All these host plants are known weeds of wheat crop in Pakistan. This work would help to identify and enlist the potential rust fungi on weeds of wheat crop that could be utilized to control these noxious weeds in future.

Presl, whose members are mostly herbs and subshrubs. During the plant pathogenic survey of Ayubia National Park, district Abbottabad, Khyber Pakhtunkhwa Province, Pakistan, and its adjacent areas conducted in October 2017 to 2018, plants of T. stewartei with powdery mildew symptoms were collected to be checked for infection with powdery mildew fungus. Disease symptoms (i.e., white powdery mycelium with blackish spots immersed in these mycelium patches covering the entire leaf) were observed. Microscopic observations showed hyaline, thin, and smooth walled, 3- to 5-μm-wide hyphae. Conidiophores were erect to bent, with one following cell, and 5 to 12 × 76 to 92 μm. Conidia were formed singly, primary conidia broadly lanceolate, apically narrowed, obtuse to pointed, and 14 to 30 × 35 to 60 μm; secondary conidia were ellipsoid or cylindrical and 12 to 30 × 39 to 55 μm. Germ tubes w...

Uredinia were amphigenous, scattered, minute. Urediniospores were globose to subglobose, hyaline to light brown, (21-) 24-33 × (24-) 31–34 (-39) µm; wall hyaline, (2.1-) 2.8- 4 (-4.4) µm thick, echinulate; germpores 1-2, tending to be equatorial. Telia were small, scattered, pulverulent. Teliospores were 1-2 celled, 1-celled spores globose to subglobose, hyaline, 23-30 × 27–36 µm; wall 2.8-4.2 µm thick, 3-5 (-7) µm thick at apex, pedicel up to 12 µm long. 2-celled spores ovate, hyaline to light brown, 23-28× 32-44 (-47) µm; wall 3-5 µm thick, reticulate, 3-5 µm thick at apex, pedicel broken mostly, up to 7 µm long. Based on these morphological traits and spore dimensions, the rust was identified as Puccinia heraclei Grev., a sample of which was deposited in LAH Herbarium (LAH Herbari...

(Asteraceae), known as flaxleaf fleabane, is a perennial native medicinal plant (Bukhari et al. 2013). In October 2018, powdery mildew symptoms were observed on leaves and stems of flaxleaf fleabane in the Upper Dir, Pakistan. White, thick mycelium appeared in effuse patches on leaves and stems. Conidiophores were erect, straight, arising from the top of hyphal mother cells, usually toward one end of the cell, 58.5 to 158 × 11.07 to 18.50 µm. Foot cells were long, straight or sometime curved at the base, 10.1 to 47.5 × 8.5 to 11.7 µm, constricted at the basal septum, followed by one to four shorter cells, producing catenescent conidia, mostly two to four conidia per chain. Conidia were broadly ellipsoid–ovoid and 25 to 37.7 × 14.2 to 18.8 µm. Germ tubes were terminal or short, tips slightly swollen. Chasmothecia were epiphyllous, scattered to loosely aggregated, globose to subglobose, light to dark brown, and 65.6 to 95.6 µm in diameter. Peridium cells were n...
