Cultivating Matsutake
Valuable edible fungi
Costing anywhere from 15 to 70 dollars per mushroom depending on the quality, matsutake mushrooms are some of the most valuable edible fungi in the world. Revered for their delicate scent, matsutake mushrooms are cooked in rice or soups as an Autumn celebration delicacy in Japan. However, there is no way to cultivate matsutake mushrooms and naturally occurring habitats are decreasing with fewer forests conducive to their growth with the changing climate.

Corresponding author Professor Akiyoshi Yamada of Shinshu University's Department of Agriculture, Department of Bioscience and Biotechnology, and Institute for Mountain Science with 9 other researchers set out to present concrete evidence that matsutake spores germinate, reach the roots of the host, and coexist to produce offspring that starts a new symbiosis.
When matsutake spores germinate, mycelia in the soil corresponding to their parents induce germination and form a genetically diverse population on the root system of the host. It is therefore hypothesized that the next generation can be created while maintaining a diverse pool.
With this novel experiment, matsutake mushrooms and Japanese red pine were cultured in a vessel, and spores collected from the fruiting bodies of matsutake mushrooms collected outdoors were inoculated to germinate in order to successfully establish a new hypha in the roots of Japanese red pine.
The researchers were successful in germinating the spore of matsutake by proving that artificially controlling the phenomenon of generational change of matsutake mushrooms in the natural world. They hope to establish an artificial cultivation technique for matsutake mushrooms in the forest.
Since this study introduces fresh matsutake spores into the experimental system, it is difficult to carry out this study unless there is a supply of matsutake nearby. In other words, it can be said that this research finding best utilized the location of the Faculty of Agriculture, Shinshu University to germinate the spore of matsutake, the most valuable wild edible mushrooms in the world.
