TL;DR: It is hypothesized that the endophytes, in contrast to known pathogens, generally have far greater phenotypic plasticity and thus more options than pathogens: infection, local but also extensive colonisation, latency, virulence, pathogenity and (or) saprophytism.

TL;DR: The distribution suggests that the some of the yeasts diversified by a process of horizontal transmission in the habitats and subsequent specialization in association with insect hosts, leading to high yeast diversity in a previously unexplored habitat.

TL;DR: P. kernoviae is the latest of several invasive tree Phytophthoras recently identified in the UK, and is especially noted for causing bleeding stem lesions on mature Fagus sylvatica and foliar and stem necrosis of Rhododendron ponticum.

TL;DR: The maize endophyte Acremonium zeae is antagonistic to kernel rotting and mycotoxin producing fungi Aspergillus flavus and Fusarium verticillioides in cultural tests for antagonism, and interferes with A. flavus infection and aflatoxin contamination of preharvest maize kernels.

TL;DR: In this article, the phylogenetic relationships of Paecilomyces sect. Isarioidea species were analyzed using the β-tubulin gene and ITS rDNA, and a group was recognized as the Isaria clade to be monophyletic.

TL;DR: The phylogenetic relationships between the different species of Fusarium commonly occurring on Norwegian cereals and some of their closest relatives are determined, as well as to reveal underlying patterns such as the ability to produce certain mycotoxins, geographic distribution and host preferences.

TL;DR: It is found that G6PD has a role in the mechanism of protection against superoxide and peroxide stresses, and the activation of antioxidant enzyme defence was blocked by the translation inhibitor, cycloheximide, suggesting that there was de novo enzyme synthesis.

TL;DR: This review considers aspects of the distribution, dynamics and translocatory activities of individual basidiomycete mycelia in forest soil, highlighting current gaps in understanding and possible ways to address these.

TL;DR: Monitoring of Cladosporium cladosporioides, C. herbarum and Alternaria spp.

TL;DR: The diversity of the endophyte assemblages was low and no host specificity among endophytes was observed, however, the frequencies of colonization of the few endophyta species recovered were high and comparable to those reported for tropical plant hosts.

TL;DR: Combined analyses of ITS and LSU rDNA sequences were utilized to resolve the phylogenetic relationships of 98 members of the smut genera Lundquistia, Melanopsichium, Moesziomyces, Macalpinomyces and Sporisorium, and Ustilago.

TL;DR: For a better understanding of the role of compounds in the AM symbiosis, studies should not be conducted only with one AM fungus looking at one fungal growth parameter such as spore germination or hyphal length, but should be wider, including several growth parameters and several AM fungi.

TL;DR: The phylogeny of Lecanoromycetes (Ascomycota, Fungi) is investigated utilizing parsimony and Bayesian Markov Chain Monte Carlo analyses, and it is suggested that Acarosporaceae, Candelariaceae, Phlyctis and Pycnora are not members of the monophyletic LECanorales, and that Timdalia and Pleopsidium are members of a monophyletsporaceae.

TL;DR: Fungi display more complex behaviours than generally acknowledged, i.e. they are able to recognize potential contestants and built up defence reactions involving evolutionary conserved enzymes and likely involved in signalling rather than playing a direct toxic role.

TL;DR: The morphology of this presumably undescribed species of Peronospora is described and illustrated and PCR primers for real time PCR analysis have been developed for the specific detection of this downy mildew pathogen from infected tissues or seeds.

TL;DR: Cumulative mass loss, ergosterol content, and species richness of released aquatic hyphomycete conidia increased with time, and numbers and richness of attached conidia were highest on days 1 and 2, and the molecular diversity was highest on day 2 and 3 on all substrates.

TL;DR: Possession of laccase genes was relatively widespread among basidiomycetes, and is shown for the first time in Xylariaceae, and all sequences were highly conserved with no variation resulting in changes to predicted amino acid sequence.

TL;DR: It is suggested that ISSR markers can be used as robust molecular markers for the population genetics, epidemiological and ecological studies of entomopathogenic fungi.

TL;DR: Findings support earlier observations that mycotoxin production in the F. graminearum clade is not species specific, but suggest maintenance of chemotype diversity through speciation may have been restricted to a subset of species.

TL;DR: In this paper, the D1-D3 domains of the nuclear gene for the ribosomal large subunit were analyzed using a Bayesian Markov chain Monte Carlo approach.

TL;DR: The comparison of nuclear small-subunit ribosomal DNA sequences of 30 species assigned 22 to Leotiomycetes, four to Dothideomycettes, three to SordariomycETes, and one to Orbiliomycetus, however, Clavariopsis aquatica and Tumularia aquatica separated from Anguillospora longissima.

TL;DR: It is shown that there is specificity for fungal partners within the orchid genera Acianthus, Caladenia and Pterostylis, and that the fungal endophytes isolated from the three Pterstylis species were probably Thanatephorus species.

TL;DR: A database containing details on fungus forming the ECM, host tree, country where the material for description was collected, and habitat of theECM is built to address the gaps in ECM knowledge that mycorrhizologists should address in future studies.

TL;DR: It is suggested that the Micareaceae is reduced to synonymy with the Pilocarpaceae, which also includes the Ectolechiaceae, and that Micarea may have to be divided into a series of smaller genera in the future.

TL;DR: It is shown that Pr1 is also up-regulated during the final stages of pathogenesis as the fungus emerges from the dead host and subsequently conidiates on the cadaver.

TL;DR: Based on the plant biomass, P uptake and forskolin content per plant, Glomus bagyarajii was found to be the best AM symbiont for inoculating C. forskohlii, next being Scutellospora calospora.

TL;DR: Host specificity was found to be of limited phylogenetic significance, and several host shifts are suggested to have occurred during the evolution of Cordyceps, thus making CordyCEps paraphyletic as suggested in other studies.

TL;DR: This study provides sequence based phylogenetic evidence of two species and when taken together with biological differences reported, leads to the recognition of M. nivale as indicated by the EF-1alpha based primers developed in this study.

TL;DR: In the present study, fungi were isolated from foliage and wood of Eucalyptus in native forests and plantations in Australia and although these fungi produced Dichomera anamorphs in culture, they clustered within the Fusicoccum clade of Botryosphaeria based on their ITS sequence data.
