TL;DR: The ecologically and economically important arbuscular mycorrhizal fungi, crucial in the ecology and physiology of land plants, and the endocytobiotic fungus, Geosiphon pyriformis, are phylogenetically analysed by their small subunit (SSU) rRNA gene sequences and placed into a new monophyletic phylum, the Glomeromycota.

TL;DR: The number of known species of fungi is estimated as at least 74 K, but could be as much as 120 K with allowances for ‘orphaned’ species as discussed by the authors, which is the current working hypothesis for the number of fungi on Earth.

TL;DR: It was concluded that a new Phytophthora species, described here as P. ramorum sp.

TL;DR: This work uses similarity indices to assess host preference and spatial heterogeneity of endophytes associated with two co-occurring, but distantly related, understorey tree species in two sites of that forest, and assess the utility of indices based on frequencies of morphospecies occurrence and on presenceabsence data.

TL;DR: A strain of Agrobacterium tumefaciens strain AGL1(pPK2) transformed three different isolates of F. circinalum with an efficiency of 2-150 transformants 10 −5 conidia, and the T-DNA was integrated into the genome and was stable through mitotic and meiotic cell divisions.

TL;DR: Because of genetic, morphological, and mycotoxin differences, the aflatoxin producing isolates of A. tamarii are given species rank as Aspergillus pseudotamarii sp.

TL;DR: Fungal fruit bodies were surveyed on a plot area of 1500 m# from 1975‐99 (excluding 1980‐83) in the fungal reserve La Chaneaz in western Switzerland indicating that the number of species will substantially increase if the survey is continued.

TL;DR: Several of the endophytes isolated are established pathogens of banana and provide support for the hypothesis that some endophytic fungi are latent pathogens in tropical hosts.

TL;DR: The usefulness of studying the fungi of the dung microcosm as a means of rapid biodiversity assessment is considered, by comparing the results with those of a similar, but smaller, study 30 years earlier, and by examining the diversity of a sample from a subjectively poor habitat in Morocco.

TL;DR: In this article, a set of 88 Glomales SSU rRNA gene sequences from 58 isolates was analysed, comprising 39 species. But the results show that most of the primers published in earlier studies are not useful at the proposed taxonomic level.

TL;DR: A model generalised from the community development on the studied logs is proposed, and the ecological nature of the gradients expressed by the first three DCA-axes was investigated by environmental and log related variables.

TL;DR: In this paper, the authors explored the evidence for host-specificity, which is basic to our understanding of host to fungus ratios, and discussed concepts of hostspecificity and host-exclusivity.

TL;DR: The Sebacinaceae, including the genera Sebacina, Efibulobasidium, Tremelloscypha, and Craterocolla, was confirmed as a monophyletic group, which appeared distant from other taxa ascribed to the Auriculariales.

TL;DR: Seven dominant mangrove species of an estuarineMangrove forest in south India were studied for the presence of foliar endophytes and the endophyte assemblage of each mangroves species was dominated by different endophyta species.

TL;DR: The ability of fungi to grow at low water activities and low pH suggest that they may be used for the purification of gas streams containing aromatic hydrocarbons in air biofilters.

TL;DR: Minimum evolution, parsimony, and likelihood methods were used for the phylogenetic analyses of mt SSU rDNA sequences from Botryosphaeria species and related taxa, and indicated that Botriesphaeria is not monophyletic and needs additional study and substantial taxonomic revision.

TL;DR: A phylogenetic analysis of the internal transcribed spacer sequences of the ribosomal DNA (rDNA) indicated that O. neolycopersici is closely related to Erysiphe macleayae, E. aquilegiae and other Pseudoidium species.

TL;DR: The results showed that A. longipes, A. gaisen and A. alternata are different species that can be distinguished morphologically, physiologically and chemically and the continued use of the name Alternaria alternata for A. Gaisen is unwarranted and pathotypes should not be used.

TL;DR: Based on 43 taxa, the relationships of the European poroid Hymenochaetales were examined by molecular sequence data of a region of the large subunit of the nuclear-encoded ribosomal DNA to find the genera Phellinus s.

TL;DR: The two subpopulations of the Dutch elm disease pathogen Ophiostoma novo-ulmi and americana, previously known as the Eurasian (EAN) and North American (NAN) races, are redesignated as subspecies novo, which can be discriminated by their perithecial form and dimensions.

TL;DR: The phylogeny of the family Bacidiaceae was investigated using 65 nuclear ITS1-5,8S-ITS2 ribosomal DNA sequences, which suggests that the Bacidia beckhausii and B. sabuletorum groups are unrelated to Bacidia s.

TL;DR: Fungi on submerged wood in streams are a diverse group, comprising taxa from various families, and distinct fungal communities are found in tropical, subtropical and temperate regions and these are discussed.

TL;DR: This work provides evidence for the existence of four distinct Neofabraea apple pathogens including N. malicorticis, N. perennans , N. alba , and a putative new Neof abraea species that was isolated in both Europe and eastern North America.

TL;DR: The results demonstrate that some substrates support relatively specific aquatic hyphomycete assemblages and it is possible to ordinate plant litter types by means of their fungal complexes, and suggests selective colonization by fungi at least in some species.

TL;DR: Based on ITS and β-tubulin sequence data of 33 isolates, the newly introduced genus, Phaeomoniella was confirmed as being distinct from Phaeoacremonium (Pm.), andylogeny inferred from DNA sequences and cultural characteristics also confirmed the species status of Pm.

TL;DR: The results demonstrated the inability of the fungus to germinate during direct exposure to the uv-B portion of simulated sunlight, indicating that uv tolerance varies as a function of physiological state and cell-cycle phase.

TL;DR: This study has shown that ISSR fingerprinting can be a powerful tool for differentiating closely related filamentous fungi with very similar morphologies or ITS sequences, dissecting species complexes, and justifying newly described species.

TL;DR: A remarkably diverse fungal diversity may be found in the hypersaline Dead Sea waters, particularly near the outlets of less saline springs near the shore.

TL;DR: The high discrimination power of the identified microsatellites makes them a valuable tool, suited for the characterization and identification of B. brongniartii strains used as biocontrol agents.
