Abstract

This study investigated the morphology and infectivity of fine endophyte in a mediterranean environment. Five morphological groups of fine endophyte differing in up to 11 characters were present within two pot cultures of fine endophyte from south- western Australia. Occurrence and abundance of a particular type of fine endophyte were not affected by the application of calcium carbonate. It appeared that there may be more than one fungus included among the two sources of fine endophyte, however it was not possible to separate the fungi. A second experiment demonstrated that infective propagules of fine endophyte can be very small (<38 μm) and fresh roots acted as a potential source of infective propagules. There was no infectivity of fine endophyte in the soil at the end of the growing season but it reoccurred in similar quantity in the next growing season.
