Discovery of Pithomyces chartarum in Britain followed an unusual sequence of events. After catching air-borne spores in a Hirst trap in 1958, larger concentrations were sought with a Rotorod sampler. Following up the concentration gradient led to where the fungus was flourishing in a favourable environment at Virginia Water, Surrey, on debris of Holcus lanatus, from which a toxin-producing strain has been isolated. We suggest that the fungus is indigenous in specialized sites and has hitherto been overlooked. |
