The spores of Cheilolejeunea ventricosa X. L. He were cultured on MS media (without acid and vitamin, pH=6.2, with 1% agar and 1% sucrose). The sporeling development and oil body ontogeny were observed. After a 55-day-long axenic culture, young plants were obtained successfully. Sodium hypochlorite solution was used to sterilize the capsules. Our results revealed that the sterilizing treatment with 0.1% Sodium hypochlorite solution for a period of 5 seconds was optimal. Oil bodies in primary protonemata are nearly homogeneous, but distinctly compound in the leaf cells of the primary leafy shoots.
