Mycological Research News features: Nitrogen deposition and mycorrhizal community structure; and Identity the causal agent of rice blast.

This issue includes two review articles: an appraisal of endophytic fungi as a source of biologically active metabolites; and PCR-based methods for the detection and quantification of mycotoxin-producing fungi. Effects of antioxidants on toxin and enzyme production in Fusarium verticilloides and F. proliferatum have been investigated, as has the accumulation of toxins produced by the last species in maize.

Molecular phylogenetic papers describe a new order of ascomycetes for the aquatic genus Jahnula and its allies, assess relationships in the lyophyllid agarics, and provide new data supporting the isolation of the plasmodiophorids. Also reported are molecular studies on variability in Paecilomyces fumosoroseus, chromosome-length polymorphisms in Botryotinia fuckeliana (anam. Botrtyis cinera), the occurrence of the snowberry pathogen Erysiphe symphoricarpi in Europe, anamorph-teleomorph connections in Cordyceps, and four new Penicillium species with dark pigmented conidiophores.

The following new scientific names are introduced: Jahnulales ord. nov.; Patescospora gen. nov.; Jahnula siamensiae, P. separans, Penicillium boreae, P. canarinse, P. pullum, and P. subarcticum spp. nov.; and J. sunyatsenii (syn. Aliquandostipite sunyatsenii) comb. nov.
