S ummary The endophyte of Griselinia littoralis is a vesicular‐arbuscular Phycomycete which could not be induced to make more than transient growth into agar, but which survived in soil kept moist for 26 months. In two consecutive experiments using sterilized soil in which ectotrophic mycorrhizas were necessary for sustained growth of Pinus radiata the endotrophic mycorrhizas of Griselinia littoralis proved necessary for sustained growth of that species. Under the same conditions seedlings of a non‐mycotrophic tree, Myrsine australis , grew steadily. The technique used to establish mycorrhizas upon Griselinia did not stimulate its growth when mycorrhizas were not formed. It produced no symbiotic infection in P inus and only traces of it in Myrsine , and it depressed the growth of both these species. In both Pinus and Griselinia percentage composition of mycorrhizal plants was consistently higher in phosphorus and lower in nitrogen than that of non‐mycorrhizal plants. Enhanced phosphorus uptake thus appears to have been the main favourable effect of both types of mycorrhiza.
