Russula ahmadii, a new species and its ectomycorrhiza are described and illustrated from coniferous forests of Pakistan, based on morphological characteristics and molecular phylogenetic data. The species is characterized by small to medium size basidiomata, a dark brown to greyish brown, tuberculate striate, and depressed pileus with dark brown spots in the centre, a chambered stipe having brownish patches towards the base, globose to subglobose amyloid basidiospores, having covered with bifurcated verrucose ornamentation connected by partial reticulum. Its ectomycorrhiza is typical of the genus Russula and is characterized by the presence of abundant lageniform cystidia with a straight neck and branched emanating hyphae with frequent clamp connections. Phylogenetic analyses based on ITS and LSU sequences support erection of the new species. Phylogenetic network analysis revealed its close position to R. pectinatoides. ITS sequences from ectomycorrhiza of Cedrus deodara also cluste...

Fleshy pored mushrooms is the name given to boletes due to their porous hymenium and fleshy nature. These are ectomycorrhizal basidiomycetes found in all continents except Antarctica. These mushrooms are important economically due to their edibility and medicinal value. This research work highlights the diversity of boletes in Pakistan and their correct identification by using molecular phylogenetic techniques. Western Himalayan range (WHR) of Pakistan is considered as diversity rich area. During present investigation regarding diversity of boletes in these areas, two bolete taxa viz. Hortiboletus rubellus and Neoboletus luridiformis were found under conifers. These mushrooms were collected and analyzed morphologically as well as phylogenetically by using Internal Transcribed Spacer (ITS) region of nrDNA sequences, and compared with their allies. All description and comparison with related taxa is provided in detail. These boletes are first time analyzed using molecular method from Pakistan.

Basidiomata of Russula livescens and its ectomycorrhiza were collected and described morphologically and molecular phylogenetically from different coniferous forests of Pakistan. The species is characterized by creamy white lamellae, fusoid pleurocystidia, ellipsoid basidiospores with reticulations and warts as wall ornamentation. Ectomycorrhiza of the taxon is dichotomous to coralloid with spiny appearance, pseudoparenchymatous mantle layers; branched emanating hyphae have frequent clamp connections and bottle shaped cystidia with a septum. Phylogenetic studies revealed that sequences generated from Pakistani specimens are closely related to sequences from China. Occurrence of R. livescens in the form of basidiomata is an addition to the macrofungi of Pakistan.

Inocybe kohistanensis, a new species is described from Swat, Khyber Pakhtunkhwa, Pakistan on the basis of morphological characters as well as molecular phylogenetic analyses. The novel species is characterized by a fibrillose reddish brown pileus, pruinose stipe with a prominent marginate bulb, and nodular spores. Sequences from the internal transcribed spacer region suggest that I. kohistanensis is distinct from all other Inocybe species sampled.

Abstract —Ascomata of Peziza succosella and its ectomycorrhiza associated with Cedrus deodara were collected from the Himalayan moist temperate forests of Pakistan. The fungal partner in the ectomycorrhiza was identified by sequencing the rDNA internal transcribed spacer region. The morphology of the taxon is also described. Ascomata are characterized by grayish brown deep cupulate apothecia while the ectomycorrhiza is characterized by a thin pseudoparenchymatous mantle with a few emanating elements. Peziza succosella and its ectomycorrhiza are an addition to the mycoflora of Pakistan and this is the first report of ectomycorrhizal association of P. succosella with Himalayan cedar.

Ectomycorrhizal roots sampled from the mycorhizosphere of Populus ciliata from Himalayan moist temperate forests of Pakistan were characterized based on standard methodology for morphological and anatomical characters which include: morphology of ectomycorrhizal system, structure of mantle layers in plain view, structure of rhizomorphs, shape of cystidia and features of emanating elements. Two distinct types of ectomycorrhize were found and briefly described. Characteristic features of these ectomycorrhizae were dichotomously branching pattern, pseudoparenchymatous mantle and branched emanating hyphae with septations. The two new types of ectomycorrhizal morphotypes are found undescribed previously and are given tentative names until their mycobiont is identified.

Populus cilliata and P. euramericana grow in Himalayan Moist Temperate forest of Pakistan, Lahore and its adjacent plains, respectively. Both these species were explored to know the ectomycorrhizal fungal diversity associated with their root system. Morpho-anatomically, 18 ectomycorrhizal types were identified growing in two different ecological zones. Moist temperate region was richer as compared to semiarid region as 15 species were found in association with P. cilliata growing there, while only three were found forming mycorrhizae with P. euramericana. The difference in ectomycorrhizal community composition supported the concept that soil nutrients, organic matter, pH, moisture content and temperature are very important factors to facilitate the growth of mycobionts and their association with roots of higher plants.

Ectomycorrhiza is a mutualistic symbiotic relationship between the roots of higher plants and fungi. Salix is an important host
genus for ectomycorrhizal symbiosis growing in a variety of environmental conditions. Eleven different types of
ectomycorrhizal morphotypes were isolated from different species of Salix growing in two geologically distant zones of
Pakistan with varied environmental conditions. KPK zone has moist temperate while Lahore zone falls in semi-arid climate.
These morphotypes were characterized on morpho-anatomic basis. Out of these eight belonged to KPK zone and three to
Lahore zone. Three morphotypes were previously undescribed and six have been found for the first time associated with Salix
spp. Two are new records for Pakistan. Species richness and diversity was found higher in KPK zone as compared to Lahore
zone where species richness and diversity was lower but a high number of ectomycorrhizal morphotypes were found in
comparison with KPK zone.
