This month Mycological Research News features a report of an extraordinary richness of undescribed truffle-like fungi in Australia, and an explanation of why mycologists should always deposit voucher specimens and cultures to enable their work to be validated, co-authored by 18 mycologists.
Amongst the 21 papers included in this issue are three on the biocontrol of insect pests by Erynia and Metarhizium species, including methods of application and longevity of conidial preparations. Biomass estimations by ergosterol in decomposing leaves in the Everglades, and by chitin in Crinipellis infections on cacao are described. Variation in Phytophthora infestans provides evidence of heterokaryons, conidial production in Colletotrichum acutatum is favoured by monsoon conditions, and the conidia of Pestalotiopsis neglecta inhibit other fungi. Six papers on mycorrhizas address competition with saprobic fungi and other ectomycorrhizal species, the characterization of a chitin synthase, variation at the molecular level in two endomycorrhizal fungi, a culture technique, and the early response of tobacco roots to colonization. Amongst other papers are ones characterizing a protease in Schizophyllum, describing incompatability groups in Pleurotus tuberregium, and showing different Venturia species attack different pears.
