Abstract: (/) The morphology and anatomy of the ectotrophic mycorrhizas of silver beech (Nothofagus menziesii) are described. Their structure is similar to that of mycorrhizas of Fagus sylvatica.
(2) The endophyte or endophytes of silver beech are not restricted to soils in which beech trees are growing or have recently grown. Keeping soil in an air-dry condition for seven months did not eliminate its infectivity.
(3) A relationship between light intensity and degree of mycorr-hizal infection was demonstrated in silver beech.
(4) Myccorrhizal and non-mycorrhizal plants of silver beech and Pinus radiata were grown in a similar series of media. Under infertile conditions, silver beech showed no benefit from the association but growth of Pinus radiata was increased thereby. In fertile media mycorrhizal beech and pine plants grew as-well as non-mycorrhizal plants.
