SUMMARY Spread of Glomus caledonius and Glomus mosseae was monitored 3, 15 and 21 months after inoculation in the field. The occurrence of their characteristic spores or sporocarps was used to establish their presence. Thirteen weeks after inoculation, G. caledonius had spread an average of 7.5 cm and a maximum of 22.5 cm from the point of inoculation. After 15 months its spores were irregularly distributed all over the plot irrespective of the initial inoculation points and the fungus had bridged a gap of 4.5 m between inoculation points. After 21 months G. caledonius spores throughout the plot had multiplied about fivefold since the previous survey and many G. mosseae sporocarps were also present. Spores and sporocarp numbers were more similar to those in pot cultures than in normal field situations. Inoculation had residual effects within the plot on the growth of lucerne sown 12 months after inoculation and cut 3 months later.
