This month Mycological Research News features group sex in New England, the recovery of viable fungal spores from 140 000 year old glaciers, and the role of ericoid mycorrhizas in conveying arsenate resistance to their plant partners.

The lead paper in this issue is an historical and morphological critique of the supposed differences of gasteromycetes from other basidiomycetes. Amongst the other 17 papers in this issue are molecular studies on Ganoderma in Australia, Melampsora on Salix, Phaeosphaeria sexual progeny, endomycorrhizal Pisolithus isolates, and cultured and in situ wood decomposing fungi. Complementary isozyme studies on Ganoderma in Australia are also presented. Adhesion and infection in Pestalotiopsis conidia has been examined, the yeasts associated with ant mounds in Texas analyzed, dual infections of grasses with different Neotyphodium endophytes studied experimentally, the detection of Botrytis cinerea by monoclonal antibodies raised by different immunogens assessed, the action of Verticillium fungicola on Agaricus bisporus hyphae examined, and the efficacy of Fusarium tumidum isolates with biocontrol potential against gorse and broom compared. A long-fruiting population of Morchella conica is documented, and numerous isolates of nematophagous fungi have been found in sheep faeces in Brazil.

The following new scientific names are introduced: Hebeloma radicosoides, Ramularia byrsonimatis, and Rhizosphaera pseudotsugae spp. nov.; and Pseudocercospora byrsonimatis (syn. Cercospora byrsonimatis) comb. nov.
