Abstract Ninerty one of Trichoderma spp. were isolated from ginseng growing bed, dead trees and muchroom in Korea from March 1978 to June 1979. Six species were identified as T. hamatum(13 strains), T, roningii(17 strains), T. aureoviride(4 strains), but other six strains(strain No. 111, 125, 127, 130, and 503) unidentified by Rifai's key. The reason which is not identified is as following. According to Rifai's key, phialid, phialospore and colony's colour of four strains (strain No. 125, 126, 127 and 130) are like T. longibrachiatum, but they are different from Rifai's method, because sterile-hypha often appears. the fature of standard strain ATCC no. 13631 T. longibrachiatum is like ster9ile-hypha that is used strains in this experiment. The morphology of strain No.503 is the same as T. hamatum except phialospore. Gnerally, T. hamatum's phialospore is subcylindrical, but strain No. 503 is regular ovoid. Therefore, strain No.503 cannot be identified by Rifai's key. The property, strain No.111's phialid is very irregular (5-20 × 2-2.5.mu.) and its phialospore (4.0-6.0 × 3.0-4.0 .mu.) is subcylindrical, is uncomfortable to Rifai's method. The standard strains used in this experiment are 7 kinds of Trichoderma spp. received from ATCC.
