This month Mycological Research News features recent work on generic concepts in cantharelloid fungi, and ectomycorrhizal fungi raiding saprotrophic ones for nutrients. Amongst topics covered by the 18 research papers in this issue are molecular systematics of Craterellus, variation at the molecular level in Chondrostereum purpureum and Monascus, genetic exchange between Metarhizium strains, β-1,3-glucanase regulation in Trichoderma harzianum, specific isozymes in Botrytis cinerea, lipid and fat composition of arbuscular mycorrhizal fungi, PCR detection of Verticillium chlamydosporium, the storage of Erynia, destruxin production by Metarhizium strains, ultrastructure of Entomosporium mespili, utilization of various substrates by Aspergillus fumigatus, Tuber melanosporum inoculation and molecular detection, and studies on freshwater ascomycetes from Thailand and Crepidotus species in Mexico. New scientific names introduced are: Botryobasidium musaisporum, Deltosperma oblongum, Melanochaeta garethjonesii, Ophiostoma setosum, Unguiculariopsis changbaiensis, and C. damingshanica spp. nov.; and Craterellus ignicolor (syn. Cantharellus ignicolor) comb. nov.
