Abstract
Four different species of Trametes were collected during a field survey in Malakand district, Khyber Pakhtunkhwa, Pakistan. Based on morphological characteristics and the molecular data from internal transcribed spacer rDNA and large subunit nLSU, the species were identified as T. elegans, T. gibbosa, T. hirsuta and T. trogii. A literature review confirms T. elegans, T. gibbosa and T. hirsuta species to be the first records from Pakistan and comparison with herbarium specie confirms its identity.

Introduction
Trametes Fr. (Fries, 1836) is genus in the family Polyporaceae with Trametes suaveolens (L.) Fr. as type species (Fries, 1838). It is characterized by the combination of pileate basidiocarps, poroid hymenophore, trimitic hyphal system, thin-walled smooth basidiospores not reacting in Melzer’s reagent and production of a white-rot to woods. It is a cosmopolitan genus present in almost all type of forest ecosystem in temperate, boreal, and tropical areas [1]. Trametes versicolor (“turkey tails”) is among the most common and widespread species of mushroom-forming fungi. It has been recorded on, angiosperms (e.g., Acer, Betula, Eucalyptus, Malus, Populus, Quercus) and conifers (e.g., Abies, Cupressus, Larix, Pinus) [2,3]. Despite the high biodiversity of the Brazilian Amazonia, the knowledge about Trametes is still scarce, using hyphal types, Ryvarden classified 16 genera (Cerrena, Coriolopsis, Cryptoporus, Daedaleopsis, Datronia, Earliella, Elmerina, Fomitella, Hexagonia, Lenzites, Megasporoporia, Microporus, Mollicarpus, Pycnoporus, Trametes and Trichaptum) as belonging to the Trametes group and with only nine species reported: T. cotonea, T. cubensis, T. lactinea, T. marianna (Pers.) Ryvarden 1973, T. maxima, T. membranacea, T. modesta, T. pubescens (Schumach.) Pilát 1939, and T. villosa [4].

However, it is difficult to identify many species of Trametes and their related genera due to their highly similar morphological characteristics [1]. Thus, Trametes is regarded as one of the most confused group of genera in Polyporaceae. Actually, the current taxonomy of Trametes has been questioned by Zhang, et al., [5]. In recent years, mycologist have attempted to use sequence data to resolve the taxonomic problems in Trametes and in the related genera [6-9]. Zhang, et al., (2006) noted thatthe results based on molecular phylogenetic analysis areconsistent with morphology in Trametes, and that ITS sequences are useful in distinguishing the genera with similar morphological characteristics [5].
In Pakistan, eleven Trametes species have been reported previously by Ahmad [10]. Tramates cingulata Berk, T. corrugata (Pers. Ex Fr.) Bres, T. dickensii Berk., T. hispida Bagl., T. ijubarksii pilat., T. incana Berk., T. lactinea (Berk.)T. roseola Pat. and Har.T. incerta (Curr.) Cooke and T. suaveolens (L.) Fr. T. Trogii Berk.,on logs and stumps of angiosperm and gymnosperm trees.
During our studies on the diversity of polyporoid fungi in Khyber Pakhtunkhwa Forests, an unreported Tametes species were found. The basidiomata were identified using morphological characters and sequence analyses of Internal Transcribed Spacer (ITS) rDNA region supported the identification. A detailed description of the species and a key to the Pakistani Trametes species are provided below.
Material and Methods
Macro-Microscopic observation
Collections of the basidiocarps are based on regular field visits to the forests of Malakand district, KP Pakistan during 2015-16. Important macroscopic features were noted from fresh specimens using a field notebook. The specimens were dried using a fan heater with temperature adjusted at 40°C.
Macro and microscopic basidiocarp features were noted. Measurements and drawings were made from slide preparations mounted in a drop of lactic acid or Melzer’s reagent or 5% KOH and Congo red on slides and were observed. Anatomical features were measured using calibrated Piximetre software connected to a B-350 Optika compound microscope through a Scope Image (H9D) microscopic camera and visualized on a computer screen.
Twenty basidiospores, basidia, and cystidia were measured and recordedas follows: Q = the length/width ratio of a single spore; Qe = average length/width ratio of all spores; Me = average L × W of all spores measured.
DNA extraction, amplification, sequencing and molecular phylogenetic analysis
About 50 mg of fungus were ground into fine powder using Qiagen plant mini-kit method. The universal primer pair ITS1F, ITS 5 and ITS 4 (Gardes, et al., 1993 and White, et al., 1990.) was used to amplify the rDNA 18s ITS (ITS1F+5.8s+ITS4) and LSU primer pair LROR, LR5 and LR7 (Vilgalys and Hester, 1990) was used to amplify the 28s larger sub-unit region in 25 μl reaction volumes following Gardes, et al., (1993) [11,12]. The PCR products were sequenced by Sanger Sequencing – Bauer Core Facility – Harvard University, USA. BLAST analysis was performed using the National Center for Biotechnology Information (USA) database, and closely matching sequences were downloaded for further phylogenetic analysis. Sequences were aligned using cipres science gateway (https://www.phylo.org/). Sequences are deposited in GenBank.

Molecular Phylogenetic analysis
The ITSIF, ITS5 and ITS4 regions amplified were a 640bp and 1200bp LSU region were amplified by LROR, LR5 and LR7. The initial BLAST comparison of the Pakistani ITS+LSU sequences showed 100% identity and 99% query cover with Trametes elegans (JN164921.1 and JN164996.1), T. gibbosa (KC589144.1 and KX449481.1), T. hirsuta (JF439511.1 and FJ550367.1) and T. trogii (EU790491.1 and JN164936.1). From Genbank Identical sequences were retrieved and were aligned through online muscle tool. The phylogegenic treatment clusters our Pakistan sequences with the T. hirsuta, T. gibbossa, T. trogii and T. elegans sequences into separate into their respective clades with a strong 99-100% of bootstrap value.
Using the online MUSCLE (version 3.8), these ITS+LSU sequences were aligned with the sequences generated in this study. Bootstrap analysis with maximum probability (ML) was performed in MEGA7 using Bio NJ and Neighbor-join. Estimates were made using the Maximum Composite Likelihood (MCL) criterion. Consequently, topology with the highest probability value for log was selected (Fig. 1).
For scaling the tree, number of replacements per site was used. It illustrates the genetic make-up of the taxa studied by including a consensus bootstrap tree constructed from 1000 replicates. The study was performed on 63 representative sequences. There were a total of 1056 positions in the final dataset after trimming both 5′ and 3′ ends of the aligned sequences. Of these, conserved were 530, variables were 263 and parsimonies informative were 204 and singletons were 59. The resulting tree have dataset of only 613 positions. The analysis included both the coding and non-coding positions. No account has been taken of those positions in which data was missing. In this phylogram Daedalea dickinsii was used as out group. Pakistani specimens are represented by ●.

Discussion
Previouly ten Trametes species were reported from Pakistan that was found on logs and stumps of angiosperm and gymnosperm trees (Ahmad and Ahmad 1956, 1967, 1969 and 1972). But during our study on diversity of polyporoid fungi from KhyberPakhtunkhwa Forests Pakistan, an unreported four species of trametes were found i,e; T. gibbosa onolea twig, T. hirsuta on treetrunk of Broussonetia papyrifera, Trametes elegans, and T. trogii on dead deciduous wood. While the study confirms that species of trametes has been recorded on angiosperms (e.g., Acer, Betula, Eu calyptus, Malus, Populus, Quercus) and conifers (e.g., Abies, Cupressus, Larix, Pinus [2,14,15].
Trametes Fr. is genus in the family Polyporaceae with Trametes suaveolens (L.) Fr. as type species. The basidiocarp of this species is described by the pileate feature and with poroid hymenophore and trimitic hyphal system. These species caused white-rot to woods. Their basidiospores are smooth and thin-walled and shows negative result in Melzer’s reagent. It is a diverse genus found in temperate, boreal, and tropical areas of almost all types of forest ecosystems. [15]. Previously from Pakistan Ten species of Trametes have been reported by Ahmad viz; Tramates cingulata Berk., T. corrugata (Pers. Ex Fr.) Bres., T. dickensii Berk., T. hispida Bagl., T. incerta (Curr.) Cooke., T. ijubarksii pilat., T. incana Berk., T. lactinea (Berk.) T. roseola Pat. & Har. and T. suaveolens (L.) Fr. on logs and stumps of angiosperm and gymnosperm trees.
Trametes elegans of genus Trametes in present study is illustrated as a new record from Pakistan. Its Basidiocarp is easily recognized in the field by short stipe-like base, corky and flexible when fresh, more rigid when dry. PILEUS semi-circular, upper surface white to grey and very finely tomentose, glabrous, smooth or concentrically zonate, margin thin, even or lobed. Basidiospores are cylindrical to oblong ellipsoid in shape, hyaline smooth and thin-walled, and 5-7 × 2-3 µm in size [16]. The initial BLAST comparison of this collection shows 100% maximum identity with Trametes elegans (JN164921.1 and JN164996.1) from GENBANK. Trametes elegans belongs to section trametes in Trametoid clade [17]. The molecular phylogenetic tree reveals that Trametes elegans clusters with their respective clade with strong bootstrap value [1]. T. elegans showed resemblance to Dadealea palisoti Fr. from Guanggong China; voucher number HMAS 19763 (Teng 1953) in both specimens narrow semi-dadeloid pores were found and more yellowish on the pore surface and has a dark line between the upper tomentum and the lower context was also observed. Trametes elegans of genus Trametes in present study is defined and proved as a new record from Pakistan. Its Basidiocarp is easily recognized in the field by flexible and corky in texture when fresh, and when dried it becomes more rigid, with short stipe-like base. Its pileus is semi-circular, upper surface white to grey and glabrous, smooth or concentrically zonate and very finely tomentose. Its margin is thin, even or lobed. The basidiospores of this species are smooth, hyaline, cylindrical to oblong-ellipsoid, and thin-walled in structure and it is about 5-7 x 2-3 µm in size [18]. The initial BLAST comparison of this collection shows 100% maximum identity with Trametes elegans (JN164921.1 and JN164996.1) from GENBANK. Trametes elegans belongs to section Trametes in Trametoid clade. The molecular phylogenetic tree reveals that Trametes elegans clusters with their respective clade with strong bootstrap value [1].
Trametes gibbosa (Pers.) Fr., is a member of Trametes and is illustrated as a new record for Pakistan. Basidiocarp is characterized by annual, sessile to dimidiate, usually semicircular, tough and coriaceous, upper surface at first tomentose to glabrous, azonate, at first white, often greenish at the base due to algae; margin sharp.

The ITS+LSU sequences of initial BLAST comparison of this collection shows 100% identity with T. gibbosa (KC589144.1 and KX449481.1). T. gibbosa belongs to section trametes clusters in Trametoid clade (Justo and Hibbett, 2011). The molecular phylogenetic tree reveals that T. gibbosa clusters with their respective clade with strong bootstrap value. Morphologically, trametes speciesare similar to Chinese collection of Harvard university herbaria. Trametes gibbosa shows morphological identification with Daedalea gibbosa Pers; locality; Heilongjiang, specimen number “HMAS 19761” deposited by (Teng 1956). Both having white to ochraceous, tough and coriaceous basidiocarp, pores distinctly radially elongated, angular with entire dissepiments; trimetric hyphal system; cystidia absent; basidiospores cylindrical to oblong ellipsoid, hyaline, smooth. Trametes gibbosa (Pers.) Fr., is also illustrated as a newly recorded species from Pakistan.

The ITS+LSU sequences of initial BLAST comparison of this collection show 100% identity with T. gibbosa (KC589144.1 and KX449481.1). T. gibbosa belongs to section trametes clusters in Trametoid clade (Justo and Hibbett, 2011). The molecular phylogenetic tree reveals that T. gibbosa clusters with their respective clade with strong bootstrap value [1].
Trametes hirsutais a member of Trametes and is illustrated as new record for Pakistan in this work. It is easily recognized in the field by, effused-reflexed, coriaceous when fresh Basidiocarps; pilei dimidiate, applanate to thick, upper surface hirsute, gray, concentrically zonate; margin yellowish-brown, tomentose, pore surface white to tan or cinereous, the pores are angular.

The molecular phylogenetic tree reveals that T. trogii clusters with their particular clade with a well-supported bootstrap value [1,17,18].
Conclusions
The ITS rDNA and 28s nLSU phylogenetic trees had similar topologies withtrametesspecies forming different cladesto T. elegans, T. hirsute, T. gibbosa and T. trogii with their respective tramates species (Fig. 1). On the other hand, all the analyzed trametes species were monophyletic in 18S rDNA and 28s nLSU tree, as previously suggested by Tomšovský et al. 2006 and Welti et al. 2012.
However, information regarding this species is still limited and the abilities of this species should be investigated further.
