This issue of Mycological Research News features: In this issue; and Changing the biological clock in Neurospora crassa.
Original papers in this number include morphological and molecular investigations on: Endophyllum species on asteraceous plants; Melampsora rusts on Salicaceae; myxotoxin producing Fusarium chemotypes; host specificity and nutrient uptake in Eudarluca caricis; Ampelomyces populations on powdery mildews; salt marsh populations of Claviceps purpurea; the classification of Omphalina foliacea; and endophytes in different genera of native Australian orchids.
A gene encoding a malic enzyme involved in the anaerobic growth of Mucor circinelloides is characterized. In the ericoid mycorrhizal Hymenoscyphus ericae, one paper shows how carbon availability affects nitrogen source utilisation, and another the effects of copper toxicity in relation to phosphatase activity.
The colonization of wood by airborne spores has been studied in experimental forest plots, and the climatic and altitudinal factors correlated with spore catches of Alternaria and Cladosporium determined.
Early development of Morchella fruit bodies is described and documented by scanning electron microscopy.
The following new scientific names are introduced in this issue: Endophyllum dimorphothecae sp. nov.; E. elytropappi (syn. Aecidium elytropappi) comb. nov.
