        This study was conducted to figure out whether Pinus rigida stand can produce a fruiting body of Tricholoma matsutake(pine-mushroom), which requires specific symbionts for survival, or not. The study site was located in Sancheong, Kyeongsangnam-do, Korea. We conducted timber cruise to figure out the circumstances of the stand, investigation of pine-mushroom production within each fairy-ring, identification of tree species by the roots collected from the fairy-rings using PCR-RFLP technique. The pine-mushroom was produced continuously from 1999 to 2003, and the productive area was about 0.111a. In this stand, Pinus rigida were planted in 1970 after harvesting of P. densiflora, which was showing about 3,000 trees/ha of stand density with average height and DBH as 7m and 12.5cm, respectively. The average diameter of the fairy-ring was 2.5m, which made us to infer the formation of fairy-ring was initiated during early 1990s with considering the annual growth rate of the fairy-ring of T. matsutake as 10cm/year. The mycorrhizal roots collected from the fairy-ring of T. matsutake was mixed with the roots of P. dens{flora and those of P. rigida with the portion of 38.3%(23/60) and 61.7%(37/60), respectively. The whole roots collected from a certain plot were identified as the roots of P. rigida. This phenomenon may indicate that P. rigida alone can produce the pine-mushroom. The observation is the fnst report on the production of fruiting body of T. matsutake in a P. rigida stand in the world, which indicate that P. rigida can serve as a symbiont of T. matsutake. The result gives a good opportunity to reevaluate the value of P. rigida that had been planted widely for greening of denuded forest.
