Molecular identification of some wild medicinal macrofungi from Northern Iran

In last decades,macrofungi have attracted increasing attention because of their valuable nutritional and medicinal properties.In this study,a total of 180 macrofungal samples were collected from forests in Mazandaran province,Iran.The dominant orders were Polyporales(51%)and Agaricales(35%).Pure mycelial cultures were successfully obtained from 91 collected samples.Regarding morphological data,47 isolates were selected for molecular identification based on internal transcribed spacer region(ITS)sequence analysis.The results showed that the 38 macrofungal isolates were belonging to 22 species,19 genera,10 families and 5 orders.Most of the macrofungi(47%)were identified as Trametes species and Ganoderma species.Three isolates identified as Hohenbuehelia species,Polyporellus brumalis and Ceriporia lacerata were records as a new to the Iran fungal flora.This study increases the knowledge on Iranian macrofungal diversity and facilitates future genetic and biotechnological investigations on these macrofungi.

Taxonomy and phylogeny of dematiaceous coelomycetes

t Coelomycetous fungi are an artificial taxonomic group which produce conidia inside a cavity i.e.conidiomata.Coelomycetes comprise about,1000 genera and 7000 species,which can be endophytic,pathogenic or saprobic.Traditional classification of coelomycetes was previously based on morphology,such as the shape of conidiomata and mode of conidiogenesis,while it was treated as a distinct group i.e.Deuteromycotina.Sequence based taxonomic studies has been used to accommodate asexual fungi in a natural classification system,resolve generic boundaries of polyphyletic genera and species complexes,as well as establish asexual-sexual links.Nevertheless,most of genera lack sequence data,thus,morphology based identification is still important when introducing new genera or species.In this paper we illustrate,describe,and provide taxonomic notes for 235 dematiaceous coelomycetous genera,including five new genera viz.Apiculospora,Didymellocamarosporium,Melanocamarosporium,Melnikia and Paulkirkia.Phylogenetic analyses of combined sequence data are provided to show placements of dematiaceous coelomycetes in Dothideomycetes,Leotiomycetes and Sordariomycetes.One-hundred and fifty-two(65%)of genera have sequence data,thus,their taxonomic placement in a natural classification system,is listed as an outline.However,83 genera still lack sequence data,hence,they are treated as Ascomycota,genera incertae sedis.In addition,separate analyses are provided where better taxonomic resolution is needed.

Fungal diversity notes 367-490:taxonomic and phylogenetic contributions to fungal taxa

This is a continuity of a series of taxonomic papers where materials are examined,described and novel combinations are proposed where necessary to improve our traditional species concepts and provide updates on their classification.In addition to extensive morphological descriptions and appropriate asexual and sexual connections,DNA sequence data are also analysed from concatenated datasets(rDNA,TEF-a,RBP2 and b-Tubulin)to infer phylogenetic relationships and substantiate systematic position of taxa within appropriate ranks.Wherever new species or combinations are being proposed,we apply an integrative approach(morphological and molecular data as well as ecological features wherever applicable).Notes on 125 fungal taxa are compiled in this paper,including eight new genera,101 new species,two new combinations,one neotype,four reference specimens,new host or distribution records for eight species and one alternative morphs.The new genera introduced in this paper are Alloarthopyrenia,Arundellina,Camarosporioides,Neomassaria,Neomassarina,Neotruncatella,Paracapsulospora and Pseudophaeosphaeria.The new species are Alfaria spartii,Alloarthopyrenia italica,Anthostomella ravenna,An.thailandica,Arthrinium paraphaeospermum,Arundellina typhae,Aspergillus koreanus,Asterina cynometrae,Bertiella ellipsoidea,Blastophorum aquaticum,Cainia globosa,Camarosporioides phragmitis,Ceramothyrium menglunense,Chaetosphaeronema achilleae,Chlamydotubeufia helicospora,Ciliochorella phanericola,Clavulinopsis aurantiaca,Colletotrichum insertae,Comoclathris italica,Coronophora myricoides,Cortinarius fulvescentoideus,Co.nymphatus,Co.pseudobulliardioides,Co.tenuifulvescens,Cunninghamella gigacellularis,Cyathus pyristriatus,Cytospora cotini,Dematiopleospora alliariae,De.cirsii,Diaporthe aseana,Di.garethjonesii,Distoseptispora multiseptata,Dis.tectonae,Dis.tectonigena,Dothiora buxi,Emericellopsis persica,Gloniopsis calami,Helicoma guttulatum,Helvella floriforma,H.oblongispora,Hermatomyces subiculosa,Juncaceicola italica,Lactarius dirkii,Lentithecium unicellulare,Le.voraginesporum,Leptosphaeria cirsii,Leptosphaeria irregularis,Leptospora galii,Le.thailandica,Lindgomyces pseudomadisonensis,Lophiotrema bambusae,Lo.fallopiae,Meliola citri-maximae,Minimelanolocus submersus,Montagnula cirsii,Mortierella fluviae,Muriphaeosphaeria ambrosiae,Neodidymelliopsis ranunculi,Neomassaria fabacearum,Neomassarina thailandica,Neomicrosphaeropsis cytisi,Neo.cytisinus,Neo.minima,Neopestalotiopsis cocoe¨s,Neopestalotiopsis musae,Neoroussoella lenispora,Neotorula submersa,Neotruncatella endophytica,Nodulosphaeria italica,Occultibambusa aquatica,Oc.chiangraiensis,Ophiocordyceps hemisphaerica,Op.lacrimoidis,Paracapsulospora metroxyli,Pestalotiopsis sequoiae,Peziza fruticosa,Pleurotrema thailandica,Poaceicola arundinis,Polyporus mangshanensis,Pseudocoleophoma typhicola,Pseudodictyosporium thailandica,Pseudophaeosphaeria rubi,Purpureocillium sodanum,Ramariopsis atlantica,Rhodocybe griseoaurantia,Rh.indica,Rh.luteobrunnea,Russula indoalba,Ru.pseudoamoenicolor,Sporidesmium aquaticivaginatum,Sp.olivaceoconidium,Sp.pyriformatum,Stagonospora forlicesenensis,Stagonosporopsis centaureae,Terriera thailandica,Tremateia arundicola,Tr.guiyangensis,Trichomerium bambusae,Tubeufia hyalospora,Tu.roseohelicospora and Wojnowicia italica.New combinations are given for Hermatomyces mirum and Pallidocercospora thailandica.A neotype is proposed for Cortinarius fulvescens.Reference specimens are given for Aquaphila albicans,Leptospora rubella,Platychora ulmi and Meliola pseudosasae,while new host or distribution records are provided for Diaporthe eres,Di.siamensis,Di.foeniculina,Dothiorella iranica,Do.sarmentorum,Do.vidmadera,Helvella tinta and Vaginatispora fuckelii,with full taxonomic details.An asexual state is also reported for the first time in Neoacanthostigma septoconstrictum.This paper contributes to a more comprehensive update and improved identification of many ascomycetes and basiodiomycetes.
