The capability of several fungal species, collected in the held in ass
ociation with species of the genus Pinus, to form ectomycorrhizae with
Pinus radiata have been determinated in vitro and in containers. Hebe
loma longicaudum, Russula sanguinea, Tricholoma albobruneum, Tuber bor
chii and Xerocomus badius have formed ectomycorrhizae with Pinus radia
ta by pure culture synthesis. These species and other three, Boletus p
inophilus, Gautieria othii and Scleroderma polyrhizum, have formed ect
omycorrhizae in open containers by methods of vegetative mycelial inoc
ulation and spore inoculation These eight symbioses with Pinus radiata
have not been previously described.
