Diversity of macrofungi and its distribution pattern of Gorakhpur District,Uttar Pradesh,India

The present study deals with the status of macrofungal diversity in Gorakhpur district and its distribution pattern.The macrofungal survey was undertaken during 2011-2014 in different localities of Gorakhpur district.A total of 114 species of macrofungi belonging to 58 genera and 33 families were collected and identified in to 31 edible species,10 excellent edible species,68 inedible species and 5 poisonous species.Agaricaceae family was found to be the dominant representing 18 species.Distribution of macrofungal species in different localities of Gorakhpur district was also evaluated on the basis of Shannon diversity index,Simpson diversity index and evenness.Highest Shannon diversity index,Simpson diversity index and evenness were found to be 3.61,0.97 and 0.90 respectively in Sahjanwan tehsil.The results indicate a very high species richness of the study site.

Clitocella(Entolomataceae)-a new genus record for India

During an exploration in the virgin coniferous forest of Jammu and Kashmir,a little known taxon,Clitocella popinalis(Basidiomycota,Entolomataceae)was gathered along with other macrofungi.Based on morphological and molecular(nrITS sequence)data,detailed taxonomic information related to this species is described and illustrated for the first time from India.Morphologically and genetically allied taxa are also compared with this species.

Taming the beast:a revised classification of Cortinariaceae based on genomic data

Family Cortinariaceae currently includes only one genus,Cortinarius,which is the largest Agaricales genus,with thousands of species worldwide.The species are important ectomycorrhizal fungi and form associations with many vascular plant gen-era from tropicals to arctic regions.Genus Cortinarius contains a lot of morphological variation,and its complexity has led many taxonomists to specialize in particular on infrageneric groups.The previous attempts to divide Cortinarius have been shown to be unnatural and the phylogenetic studies done to date have not been able to resolve the higher-level classification of the group above section level.Genomic approaches have revolutionized our view on fungal relationships and provide a way to tackle difficult groups.We used both targeted capture sequencing and shallow whole genome sequencing to produce data and to perform phylogenomic analyses of 75 single-copy genes from 19 species.In addition,a wider 5-locus analysis of 245 species,from the Northern and Southern Hemispheres,was also done.Based on our results,a classification of the family Cortinariaceae into ten genera-Cortinarius,Phlegmacium,Thaxterogaster,Calonarius,Aureonarius,Cystinarius,Volvanarius,Hygronarius,Mystinarius,and Austrocortinarius-is proposed.Seven genera,10 subgenera,and four sec-tions are described as new to science and five subgenera are introduced as new combinations in a new rank.In addition,41 section names and 514 species names are combined in new genera and four lecto-and epitypes designated.The position of Stephanopus in suborder Agaricineae remains to be studied.Targeted capture sequencing is used for the first time in fungal taxonomy in Basidiomycetes.It provides a cost-efficient way to produce-omics data in species-rich groups.The-omics data was produced from fungarium specimens up to 21 years old,demonstrating the value of museum specimens in the study of the fungal tree of life.This study is the first family revision in Agaricales based on genomics data and hopefully many others will soon follow.

Phylogeny of Entoloma s.l. subgenus Pouzarella, with descriptions of five new species from China

Taxonomy and phylogeny of Entoloma s.l.subgenus Pouzarella in China are carried out based on morphological characters and molecular data.Seven species in subg.Pouzarella are recognized in China and a key to these species is provided.Five species,Entoloma changchunense,E.crassicystidiatum,E.furfuraceum,E.subaraneosum and E.tenuissimum,are described as new;a new Chinese record E.dysthaloides is also presented in this paper.Among them,E.crassicystidiatum was discovered from southern China,and the others were found in northeastern China.Molecular phylogeny of subg.Pouzarella were conducted based on nLSU,mtSSU and RPB2,and the phylogenetic positions of the five new species are discussed.The placement of subg.Pouzarella in Entoloma s.l.clade is well resolved in all analyses presented here,and the monophyly of subg.Pouzarella is strongly supported by the morphological and molecular phylogeny.The infrageneric classifications in this group were not well recovered in the present study;and further studies based on more samples and gene loci are needed to a better understanding of the infrageneric taxa in subg.Pouzarella in the future.

Lepidostromatales, a new order of lichenized fungi (Basidiomycota , Agaricomycetes), with two new genera, Ertzia and Sulzbacheromyces, and one new species, Lepidostroma winklerianum

We present a revised molecular phylogeny of higher Basidiomycota focusing on Lepidostromataceae based on the large subunit(28S)of the nuclear ribosomal rDNA(nuLSU),with additionl data from the translation elongation factor 1 alpha 1(TEF1)and the RNA polymerase II second largest subunit(RPB2)genes.Our results suggest that Lepidostromataceae is best recognized in a separate order,Lepidostromatales ordo novum,within subclass Agaricomycetidae.Furthermore,the internal topology of Lepidostromataceae,correlating with thallus features,indicates that three genera,instead of a single genus,should be recognized.We therefore introduce the genera Ertzia genus novum and Sulzbacheromyces genus novum for Lepidostroma akagerae and L.caatingae,respectively.In addition,the new species L.winklerianum spec.nova is described for Mexican material previously identified as L.calocerum.The photobionts of Sulzbacheromyces and Lepidostroma were identified using molecular data of the large subunit of the ribulose 1,5-bisphosphate carboxylase/oxygenase(rbcL)gene,revealing a possibly undescribed genus in Trebouxiophyceae and the first report of lichenization for the genus Bracteacoccus in Chlorophyceae.
