TL;DR: Both the pathogen-host and the endophyte-host interactions involve constant mutual antagonisms at least in part based on the secondary metabolites the partners produce, and that of theendophyte and its host is a balanced antagonism.

TL;DR: The eects of a prescribed fire on the presence of ectomycorrhizal fungi on the root tips of ponderosa pine were investigated one year after a prescribed ground fire, and patchiness on a fine spatio-temporal scale caused some major changes in ranking of individual species between sample years.

TL;DR: In a 3 year study of oak decline in Central and Southern Europe, a papillate homothallic Phytophthora species was isolated consistently from necrotic fine roots by direct plating on to selective agar medium and from rhizosphere soil samples by baiting with leaves of Quercus robur.

TL;DR: Sequence analysis generally confirmed the overall taxonomy in Penicillium subg.

TL;DR: The estimation of different phosphate pools in axenic cultures and mycorrhizal roots revealed that the fungal metabolism was changed by the association with an ectomycorrhIZal host plant.

TL;DR: Based on the results of the analysis, a new combination for Pseudocercosporella aestiva is proposed in Ramulispora, and Paracercospora is reduced to synonymy with PseudodocercosPORA, with bootstrap values greater than 92% for each clade.

TL;DR: The hydrophobin SC4 was isolated from the medium of a dikaryon from Schizophyllum commune with disrupted SC3 genes and proved to be a powerful surfactant and by immunodetection SC4 could be localized lining air channels within this tissue.

TL;DR: The genetic relationships between several morphological groups recognized within Colletotrichum acutatum sensu lato were investigated using RAPD analysis and vegetative compatibility analysis and the genetic distinctness of the groups recognized morphologically is confirmed.

TL;DR: The relative contributions of intra- and extracellular enzymes to the conversion of PAH and the possible role of the fungi in the long-term detoxification of soil xenobiotics are discussed.

TL;DR: It was concluded that all the strains studied with cylindrical conidia should be placed within C. fragariae, which is confirmed as separate from C. gloeosporioides and recognized as a holomorphic taxon.

TL;DR: This study suggests that either multiple losses of toxigenicity in A. flavus and A. parasiticus have occurred, or that recombination has reassorted this phenotype into a variety of different genetic backgrounds.

TL;DR: The conidia were probably deposited at sites which are conducive for germination and infection and consequently increased the overall mortality of insects and also appeared to extract fungistatic and stimulatory compounds from the insect cuticle.

TL;DR: In this article, the development of 12 litter and seven phylloplane fungal species was examined from spore germination to colony sporulation across a series of environmentally relevant UV-B doses.

TL;DR: Despite the differences in taxa found below and above ground, similarity tests between treatments using the fruitbody data also revealed ashift in community structure, suggesting a shift in the community structure as a result of the treatment.

TL;DR: There is war in the world of lichens, illustrated under the headings of algal slaves, exploiters of two kingdoms, alien invaders, cosy niche seekers and take-over specialists.

TL;DR: The genus Zalerion is artificial; its species bear no phylogenetic relation among themselves, and a new anamorph genus and species is proposed, Glarea lozoyensis, to accommodate ATCC 20868.

TL;DR: This is the first report of isolates from hosts other than Pinus banksiana or P. resinosa, and from outside Michigan, Minnesota, or Wisconsin, that have been characterized as members of the RAPD marker group B.

TL;DR: Gypsum solubilization was predominantly achieved by both oxalic acid, which was accompanied by formation of calcium oxalate crystals, and citric acid production rather than the acidity of the medium, as well as the possible roles played by these fungi in mineral cycling.

TL;DR: This case is the first case where compelling evidence has been obtained for somatic hybridization in Prt and only the second of inter pathotype somatic Hybridization in a wheat rust under field conditions.

TL;DR: Although G. etunicatum spores formed in vitro exhibited general morphological and anatomical similarity to soil-borne inoculum, they were significantly smaller and had thicker spore walls than their soil- borne counterparts.

TL;DR: The time course of release of an extracellular matrix (ECM) from conidia of the barley powdery mildew pathogen Blumeria graminis was investigated by scanning electron and light microscopy and the ECM material stained positively for protein and could not be removed from the conidium interface by vacuum desiccation in the scanning electron microscope indicating that theECM is not simply water.

TL;DR: The 18S rDNA data shows that the base for mainstream Peronosporomycetes has been substantially increased and a new family for the Leptolegnia lineage is proposed from the Saprolegniaceae sensu lato.

TL;DR: Fungi isolated from the leafy liverwort Cephaloziella exiliflora collected in Australia and continental Antarctica were compared with Hymenoscyphus ericae using internal transcribed spacer (ITS) region DNA sequences, indicating that the fungus has a global distribution.

TL;DR: It is argued that the hyphal network is most severely disturbed and probably responsible for declines in density of fungi observed in the field following fire.

TL;DR: The objective was to evaluate relationships by analysing numerically morphological and isoenzymic data to discern the number of species occurring in southern South America, and their delimitation.

TL;DR: Two strains with known biocontrol capabilities were found to relate to the genotypic group containing Th1 and Th2 forms and, based on variation within this group, to belong to a homogeneous group of form Th1 strains.

TL;DR: The new species is characterized by the production of two types of conidiophores, conidiogenous cells, and conidia, and the potential for its development as a biocontrol agent against the pinewood nematode is briefly discussed.

TL;DR: A particular group of saprotrophic and ectomycorrhizal fungi produced reproductive structures successively on the forest floor after treatment with some nitrogenous compounds (N compounds) such as urea and aqua ammonia.

TL;DR: Both species richness and abundance of dictyostelids and myxomycetes were higher in the secondary tabonuco forest than in any of the other forest types, and the general pattern observed was that of decreasing diversity with increasing elevation.

TL;DR: Fungicide sensitivity tests using the ergosterol biosynthesis inhibitors triademinol, bromuconazole and triticonazole showed that, due to recombination, some progeny could have increased resistance to these fungicides.
