Ectomycorrhizae synthesized between Pinus radiata and eight fungi associated with Pinus spp.

The capability of several fungal species, collected in the field in association with species of the genus Pinus, to form ectomycorrhizae with Pinus radiata have been determinated in vitro and in con- tainers. Hebeloma longicaudum, Russula sanguinea, Tricholoma albobruneum, Tuber borchii and Xerocomus badius have formed ectomycorrhizae with Pinus ra- diata by pure culture synthesis. These species and other three, Boletus pinophilus, Gautieria othii and Scleroderma polyrhizum, have formed ectomycorrhizae in open containers by methods of vegetative mycelial inoculation and spore inoculation. These eight sym- bioses with Pinus radiata have not been previously described.
