The objectives of this study were to investigate the growth of Gyrophora esculanta and to establish a method of tissue culture of the plant. The results obtained were as follows : 1. The Gyrophora esculanla was found growing mostly on the rock slopes of 722 m to 1915 min elevation on mountains in Korea. 2. Trees growing in the vicinity of the G. esculanta scere mainly Qzrerczrs spp., Pinus thzenbezgii, Acer spp. and Leapedeza spp, Especially Quercus spp. was found growing in all of the study site. 3. The average Length of the rock slopes with G, e.cculartta growing on was 14 m and their aspects were mostly south. 4. The G. esculanta were found growing on rocks of Crystalline Schist, Quartz, Liparite, Granite, ete. Particularly they were mostly found on granites. The gradient of the rock slopes was in the range of 22-90 degrees. 5. The mean number of individuals of G. escaclanta per one rock slope ranged from 14 at Mt . Buk.han to 70 at Mt. Jrri. Their mean diameter ranged from 1.8cm at Mt. Munsu to 4.6cm at Mt, Sokri. 6. The average percentage of G. esczrlanta with fruit body was 17.6%. The highest value was found at Mt. Cheonhwang (24.0%) . 7. When the 100 segments of rhizoid of Gyruphora escaclarrta cultured in Detmer`s medium supplemented with kinetine 5㎎/ℓ and 2, 4-D 3㎎/ℓ, n callus of microspore origins were induced from about 20% of the segments. As the induced n callus was transplanted on the six different types of rocks, it was observed that the juvenile G. esculanta grew best on granite and the development rate of G. esczdanta on the granite was about 55%.
