The sequestrate fungi of Japan, including truffle and truffle-like fungi, have not been well characterized but are potentially diverse. We investigated the diversity and phylogeny of Japanese Octaviania specimens using a multifaceted approach including scanning and transmission electron microscopy as well as analysis of nuclear ribosomal DNA (ITS and LSU) and EF-1α (tef1) sequences. Phylogeneti...

Rhodactina is a small sequestrate genus in Boletaceae with two described species, R. himalayensis and R. incarnata. Phylogenetic analyses of a three-gene dataset including atp6, tef1 and rpb2 of Rhodactina species along with selected Boletaceae species showed that all Rhodactina species formed a monophyletic clade, sister to the genera Spongiforma and Borofutus in subfamily Leccinoideae with hi...

Stromata of Trichoderma species having green ascospores were collected in various regions of China. Based on morphology of the sexual and asexual morph, culture characteristics, and sequence analyses of rpb2 and tef1 genes, 17 species with green ascospores were identified. Among them, Trichoderma rosulatum, T. rufobrunneum and T. stipitatum are described as new species, and seven other species ...

We report the isolation of a novel agent of subcutaneous mycosis from a 45-year-old Indian male immigrant in the United States. Phylogenetic analysis of partial small ribosomal subunit and large ribosomal subunit, internal transcribed spacer, partial translation elongation factor (TEF1), and RNA polymerase second largest subunit (rPB2) loci revealed that the strain was identical to another isol...

Five loci, nucSSU, nucLSU rDNA, TEF1, RPB1 and RPB2, are used for analysing 129 pleosporalean taxa representing 59 genera and 15 families in the current classification of Pleosporales. The suborder Pleosporineae is emended to include four families, viz.Didymellaceae, Leptosphaeriaceae, Phaeosphaeriaceae and Pleosporaceae. In addition, two new families are introduced, i.e. Amniculicolaceae and L...

The genus Tuber ( Tuberaceae , Pezizales ) is an important fungal group of Ascomycota both economically and ecologically. However, the species diversity, phylogenetic relationships, geographic distribution in China remains poorly understood, primarily because descriptions many new relied heavily on morphological features with molecular data either not sought or ignored. misapplication European ...

During a survey of aquatic fungi from Anzali Lagoon in Iran, several fungal specimens were isolated freshwater habitats. Morphological evidence and comparing sequencing based on rDNA (ITS LSU) protein-coding genes (TEF1 TUB2) showed that some isolates belong to undescribed species. These Arthrobotrys Sarocladium, two ascomycetes genera. hyrcanus, sp. nov., differs closely related species such a...

Three novel species collected from Dinghushan Biosphere Reserve (DHSBR) in southern China, Russula cylindrica Y.Song sp. nov. and R. lacteocarpa subgenus Archaeae reticulofolia subg. Compactae, are described based on morphological molecular data. In addition, leucobrunnea nom. is proposed replacement of leucocarpa illeg. Brevipedum, as (T.Lebel) T.Lebel had been earlier. Differences between the...

Modern taxonomic studies of Agaricomycetes rely on the integrative analyses morphology, environmental data, geographic distribution, and usually several DNA loci. However, sampling selection loci for are commonly shallow. In this study, we suggest minimal numbers necessary specimens to sample analyze in order prevent inadequate decisions species groups with minor morphological genealogical diff...

The new stipitate species of Hypocrea, H. seppoi; is described, based on material freshly collected in Finland. Characterization of this species includes morphology of teleomorph and anamorph, culture studies and molecular phylogeny. H. seppoi is compared to the other European soil-inhabiting, stipitate Hypocrea species. It is characterized by small stromata, thin fibrous stipe, perithecia decu...
