Abstract
This paper presents the results of investigation on the inoculation test of fungi of the fairy rings on turfgrasses. Lepista sordida (Fr.) Singer which separated from the Zoysia grass in the golf course of the Hiroshima Kokusai Golf Club, Hiroshima Prefecture and Marasmius oreades (Bolt, ex Fr.) Fr, which separated from the Kentucky bluegrass in a private garden in San Francisco, U.S.A. were used in this experiment.
The stems of Zoysia matrella (L.) Merr. and Poa pratensis L. (Kentucky bluegrass), wounded at the somewhat upper portion of the surface of soil, were inoculated with fungus itself which has been cultured by rice and wheat bran medium (rice bram: wheat bran: water=1: 1: 2) . The inoculated plants were put in the chamber at 25°C with artificial illumination. The results of the inoculation test show that Lepista sordida (Fr.) Singer developed the symptoms on the stems and leaves of almost all plants of inoculated Zoysia matrella (L.) Merr., but of few plants of Poa pratensis L.; and that Marasmius oreades (Bolt. ex Fr.) Fr. developed the symptoms in some plants of Zoysia matrella (L.) Merr., but almost never developed on Poa pratensis L.
