Disappearance of Bacteria from the Zone of Active Mycorrhizas in Tricholoma matsutake (S. Ito et Imai) Singer

Abstract

IN coniferous forests in Japan, especially forests which contain Pinus densiflora, the edible mushroom “matsutake” (T. matsutake) forms fairy rings of fruiting bodies on the ground. The ring follows the mycorrhizal development of pine rootlets and grows outwards 10–15 cm every year. On the inner area of the fairy ring where the mycorrhizas have been decomposed, fruit bodies are seldom formed1,2.
