Under sterile conditions a mycorrhiza is formed between Aureo-basidium puHulans and Vitis riparia. The mycelium forms a dense plectenchymatic layer on the roots and a more or less complete HARTIG net between the cells of the cortex. The fungus produces a growth substance inducing internodial elongation of the plant-let even before a hyphal contact is achieved.
