Hebeloma mesopheaum (Pers.: Fr.) Quel. is a common ectomycorrhizal
fungus of Pinus pinaster var. atlantica in the Mamora forest. Their fruit
bodies are frequently observed each year during the autumn Saison. The fungus
was isolated easily from collected sporocarps and the pure culture obtained
colonizes rapidly the MNM culture medium.
In the nursery, both the mycelium and spores were used as inoculum. Several
months after inoculation, the inoculated seedlings formed straight and unbranched
ectomycorrhizas with cottony mycelium. Some sporophores were formed and reached
maturity. They are similar to those occurring naturally in the field.
Key words: Hebeloma mesophaeum, Pinus pinaster, ectomycorrhizas, artificial inoculation.
