Mycological Research News features: In this issue; Molecules vs morphology; The name Fusarium moniliforme should no longer be used; and Differential use of Termitomyces by termites.

Molecular methods are used in this issue to investigate the: phylogeography of Hyphoderma setigerum, Mycosphaerellaceae on Proteaceae, Xerocomus chrysenteron complex, identification of endophytes from Pinus tabulaeformis, root-inhabiting Cryptosporiopsis spp., discrimination of Pisolithus spp., variation in Pyrenochaeta lycopersici, Penicillium nalgiovense pencillin production impaired strains, and laccase genes in Trametes sp. Sexual reactions in Zygomycota are shown to be mediated by trisporoid compounds.

The use of particle filtration to study the diversity of rainforest leaf litter fungi is applied to Neolitsea dealbata, an unclamped Lentinellus has been rediscovered (and a key to allied European species provided), and the first fossil clavarioid fungus is described from Cretaceous amber.

The following new scientific names are introduced: Palaeoclavariaceae fam. nov.; Palaeoclavaria gen. nov.; Cryptosporiopsis rhizophila, P. burmites, Xerocomus cisalpinus spp. nov.; Lentinellus herbarum (syn. Lentinus flabelliformis var. herbarum), Mycosphaerella concentrica (syn. Gibbelina concentrica), M. fibrillosa (syn. Teratosphaeria fibrillosa), M. microspora (syn. T. microspora), M. proteae-arboreae (syn. T. proteae-arboreae), X. fennicus (syn. Boletellus fennicus) combs. nov. A lectotype is designated for the name Thelephora setigera (i.e. Hyphoderma setigerum), and a neotype for Lentinus flabelliformis var. herbarum (i.e. Lentinellus herbarum).
