This number of Mycological Research News features confusion over the identity of Trichoderma strains used in biocontrol, and recent changes made to the classification of Coprinus. Attention is also drawn to the new address of the Executive Editor.

Thirteen papers are included in this issue, three with widespread implications for our understanding of particular groups of fungi resulting from a combination of molecular and anatomical studies: the European poroid Hymenochaetales, the lichenized ascomycete family Bacidiaceae, and the Exobasidiales/Microstromatales.

Other molecular studies examine Ephelis isolates on grasses, compare the β-tubulin gene of Melampsora lini with that of other fungi, establish anamorph connections and synonymy in Cordyceps sinensis, variation in Botrytis elliptica, and the identification of ectomycorrhizal fungi in Eucalyptus ecosystems.

Phosphorous uptake in Phanerochaete velutina in relation to soil water potential has been studied. In Metarhizium anisopliae, proteins formed by cold-active isolates are documented, and the effect of different UV-B wavelengths explored. Effects of heavy metals on two fungi from polluted and clean streams are compared, and fungal mycelium preserved in amber 15–45 Myr old from the Dominican Republic is described.

The following new scientific names are introduced: Volvocisporiaceae fam. nov.; Pseudoinonotus, and Volvocisporium gens. nov.; Fuscoporia torulosa (syn. Polyporus torulosus), F. wahlbergii (syn. Trametes wahlbergii), Mensularia hastifera (syn. Inonotus hastifera), M. nodulosa (syn. Polyporus nodulosus), Pseudoinonotus chrondromyelus (syn. Inonotus chondromyelus), P. dryadeus (syn. Boletus dryadeus), P. victoriensis (syn. Polyporus victoriensis), and V. triumfetticola (syn. Muribasidiopsora triumfetticola) combs. nov.
