TL;DR: Based on pathogenicity tests, C. viniferum caused leaf spots and anthracnose of table grape but was not host-specific, and was described as a novel species of Colletotrichum.

TL;DR: Six Simplicillium species were discovered from soil samples collected on the Honshu, Bonin, and Izu islands in areas under the jurisdiction of Tokyo, Japan, and five of them were previously undescribed.

TL;DR: Molecular phylogeny suggests a close relationship of Asteraceae to the early evolution of Golovinomyces, and molecular clocks for powdery mildews are designed using the 28S rDNA D1/D2 and internal transcribed spacer (ITS) regions According to these clocks, the powderY mildews originated in the Late Cretaceous and the first radiation of the major lineages occurred at the Cret Jurassic/Paleogene boundary.

TL;DR: A new species is described from Iran widely associated with dying Quercus brantii, on which it produces charcoal-like stromata and differs from the other described species, Ob .

TL;DR: I. poprawskii was shown to be closely related to I. javanica ; however, it formed its own unique clade, thus confirming its status as a new fungal species.

TL;DR: The results suggest that xylariaceous endophytes did not show host specificity and had a saprobic phase on dead leaves in their life cycles and that Xylaria sp.1 was capable of decomposing lignin in the field conditions.

TL;DR: Indole compounds were found in the fruiting bodies of selected mushroom species both before and after thermal processing, including 5-hydroxytryptophan, serotonin, indole and melatonin.

TL;DR: Seeds of Cyrtosia septentrionalis germinated in the presence of the unknown Polyporales species underwent further growth and development, as compared with the other fungi tested, when covered with soil, indicating low mycorrhizal specificity in germination.

TL;DR: Two new Daedalea species were described from South China based on morphological and molecular evidences, one of which is easily recognizable by its effused-reflexed, grayish-brown to fuscous, hispid pileal surface.

TL;DR: Chemical analysis of the organic extract of L. angustiascus revealed the presence of 6E,9E-octadecadienoic acid and ergosterol peroxide as major secondary metabolites, which support the placement and establishment of this new species in the Lindgomycetaceae, Pleosporales, DothideomyCetes.

TL;DR: The taxonomy of Tibetan Laccaria is discussed, five new species are proposed, and an artificial key that includes extralimital species from Asia is provided.

TL;DR: Two new Talaromyces species, T. thailandensis and T. tratensis, isolated from forest soil in Trat in Thailand are described and they can be distinguished by length of stipe and shape of conidia.

TL;DR: It was found that most of the phylotypes include AM fungi previously detected in high altitude regions in the Eurasian Continent, which suggested that higher plant biomass may be required for the proliferation of AM fungi in the environment.

TL;DR: Virgaria boninensis, a new hyphomycete classified in the Xylariaceae (Ascomycota), was isolated from soils in the Bonin Islands, Japan and is characterized by olive gray colonies and solitary, reniform, light brown sympodial conidia.

TL;DR: Fusarium verticillioides strains did not affect seed germination even in presence of high seed colonization, but showed a variable pathogenic behavior according to the maize growth stages, and only populations isolated at seedling and pre-silking stages showed high radicle decay ability.

TL;DR: Based on ribosomal internal transcribed spacer DNA sequence data, T. dulciolens is phylogenetically independent from T. matsutake and its allied species in southern Europe and appears to exist in North America.

TL;DR: The cloned and characterized an acetyl coenzyme A acetyltransferase gene (AACT), designated Ganoderma lucidum AACT, suggest that this enzyme may play an important role in triterpene biosynthesis.

TL;DR: Phylogenetic analyses of the 28S and ITS rDNA regions showed that S. castanopsidis formed a distinct lineage separated from Cy.

TL;DR: Phylogenetic analysis based on internal transcribed spacer and large subunit (LSU) rDNA sequences confirmed the placement of P. oligotrophica as a new species in the genus Plectosphaerella and the new species is compared to the morphologically and phylogenetically closely related species.

TL;DR: Cross inoculations using basidiospores and aeciospores confirmed the macrocyclic, autoecious nature of the life cycle in both rust populations and showed that the two populations were distinct in their host specificity.

TL;DR: High sucrose concentrations increase growth of G. virens whilst 6-kestose accumulation in the medium seems to be controlled both by specific properties of β-fructofuranosidases and on the sucrose concentration.

TL;DR: The fungal symbiont diversity of two orchid species, Habenaria radiata and Epipactis thunbergii, occupying three manmade wetlands in Hiroshima Prefecture, Japan are assessed to determine if orchids colonizing reconstructed habitats associate with a phylogenetically diverse or narrow suite of fungal Symbionts.

TL;DR: Pseudoidium javanicum is proposed as a new species based on analyses of 28S, ITS and IGS rDNA sequences, and morphological data and forms a distinct clade separated from other species of Erysiphaceae.

TL;DR: Agrobacterium tumefaciens-mediated transformation was successfully applied to mycelia of the 3 economically important mushrooms Hypsizigus marmoreus, Flammulina velutipes, and Grifola frondosa, suggesting that the C. neoformans actin promoter has a potential universal promoter activity in basidiomycetes.

TL;DR: Lecanicillium primulinum, a new hyphomycete classified in the Cordycipitaceae (Hypocreales, Ascomycota), was isolated from soils collected from the Okinawa's main island and the Bonin Islands, Japan and identified as a species of Lecanicllium which was previously undescribed.

TL;DR: This new species is characterized by its broadly lenticular ascospores with two wide equatorial crests and finely spinulose and rugose convex surfaces and produced pale pinkish exudates after 14 d incubation on Czapek agar.

TL;DR: This study confirms that Pythium is an extremely heterogenous and polyphyletic genus containing a number of distinct clades of species, including Pythiogeton, which possess morphologically distinguishable characters.

TL;DR: The results indicate that the density and diversity of ectomycorrhizal fungi decrease rapidly within several tens of meters from arbuscular mycorrhIZal forest edges.

TL;DR: Two new species of Erysiphe section Uncinula are described and illustrated based on the molecular and morphological analyses and the phylogenetic relationships of the two new species with other closely related species are discussed.

TL;DR: Phylogenetic analysis showed that the fungal sequences from these two species are included in Glomeraceae (former Glomus group A), indicating that the two Burmannia species are associated with narrow phylogenetic ranges of arbuscular mycorrhizal fungi.
