Summary Sclerotia ofColletotrichum coccodes tolerated much higher concentrations of actidione in agar than did sclerotia ofMycosphaerella ligulicola. With increase in concentration of the antibiotic sclerotia of both species took longer to germinate. Increased resistance of both species to actidione developed after growth of a single generation on media containing the antibiotic. Sclerotia ofC. coccodes survived 5 days immersion in a bacterial culture filtrate whereas scleroia ofM. ligulicola ceased to be viable after a similar period. Sclerotia ofC. coccodes andM. ligulicola exhibited “strand” and “loose” types of formation respectively. The degree of resistance of these sclerotia to antibiotic substances was correlated with both longevity in soil and type of formation, but, in general, there is unlikely to be a relationship between structure of the sclerotium and longevity.
