title: In vitro ectomycorrhizal specificity between the Asian red pine Pinus densiflora and Tricholoma matsutake and allied species from worldwide Pinaceae and Fagaceae forests.
abstract: Tricholoma matsutake produces commercially valuable, yet uncultivable, mushrooms (matsutake) in association with pines in the Far East and Scandinavia and with both pines and oaks in the foothills of Tibet. Other matsutake mushrooms, such as Tricholoma anatolicum from the Mediterranean regions and Tricholoma magnivelare and Tricholoma sp. from the North Pacific Coast area of Canada and North America as well as Mexico, respectively, are associated with pines or oaks in their natural habitats. Tricholoma bakamatsutake and Tricholoma fulvocastaneum from Asia produce moderately valuable matsutake mushrooms and are solely associated with Fagaceae in nature. In this study, we demonstrate for the first time that matsutake mushrooms from Scandinavia, Mediterranean regions, North America, and Tibet form ectomycorrhizae with Pinus densiflora similar to the Far East T. matsutake. In general, worldwide T. matsutake and the symbionts of Pinaceae colonize the rhizospheres of P. densiflora as well as T. matsutake isolated from the host plant. However, T. fulvocastaneum and T. bakamatsutake formed a discontinuous Hartig net and no Hartig net, respectively, and colonized to a lesser extent as compared to T. matsutake. The data suggest that conifer-associated matsutake mushrooms in their native habitat will associate symbiotically with the Asian red pine.
