Edible mushroom fungi in the genera Lyophyllum, Tricholoma, Leucopaxillus, Suillus, Rhizopogon, Lactarius, and Morchella were tested for mycorrhization with Pinus densiflora in vitro. Most of the tested fungi in the genera Lyophyllum, Tricholoma, Suillus, Rhizopogon, and Lactarius formed ectomycorrhizas 2–4 months after fungal inoculation. Mycorrhizal seedlings were then acclimatized in open-pot soil under growth-chamber conditions. Almost all mycorrhizal seedlings sustained their symbiont and developed new mycorrhizas for 8–9 months after transplantation. Under these conditions, more than half of the tested species formed primordia and Tricholoma flavovirens, Rhizopogon rubescens, and Lactarius akahatsu developed basidiocarps with young host plants.
