The roots of
Cedrus atlantica grown in a cedar forest soil under gnotoxenic conditions formed a mycorrhizal association with
Tricholoma tridentinum Singer var.
cedretorum Bon when this fungus was inoculated into the soil as a mycelial form. This association was not observed when plants were grown
on an artificial substrate or when mycelium was immobilized in a calcium alginate gel. The influence of host receptiveness,
fungal survival and cultural conditions on the mycorrhizal infection of
C. atlantica is discussed.
