SUMMARY Oidiodendron griseum, O. cerealis, O. rhodogenum, O. tenuissimum and O. truncatum were tested for their endophytic ability on axenic seedlings of Vaccinium angustifolium grown on a synthetic nutrient medium. O. griseum, O. rhodogenum and O. cerealis produced typical intracellular hyphal coils characteristic of the ericoid infection. For these three species, the level of infection reached 9 to 21 % of the root cells after 60 d of incubation. O. truncation and O. tenuissimum did not infect the Vaccinium roots but the latter species stunted development of secondary roots and reduced the growth of the seedlings.
