In 1985-1987, the ecology of Shiro which had produced fruiting-body of Tricholoma matsutake was studied in the forest of Pinus densiflora, Sadogashima, Niigata Prefecture. There are three types of Shiro showing circular and crescent with pine root and independent circular with pine root. The latter one developed in the soil which the root of pine tree did not grow well. When the mycelia from the latter Shiro are mixed with the sawdust medium containing several nutrients and LVD (separated sulphite pulp waste from softwood) and incubated in the plastic case at 24°C, the fruiting-body of T. matsutake was formed 90 days after the mixing. The growth of mycelia (Z-1 strain) isolated from the fruiting-body formed in the plastic case was better than those produced in nature. Moreover, Z-1 strain formed some small fruiting-bodies in the sawdust nutrient medium containing LVD and Sphagnum sp. (commercial plant) . Other strains, however, did not form any fruiting-body in the same culture conditions. Therefore, the mycological and physiological characters of Z-1 strain isolated will be examined in further investigation.
