Abstract: This paper records 11 species and varieties, including 1 new variety. They belong to 8 genera and 4 families of Cyanop hyta, respectively. They are Chroococcus tenax (Kirch) Hieron var. minor. var. nov.; Gloeocapsa montana Kutzing; Gloeocapsa incrustata Chu; Gloeocapsa ralfsiana (Harvey) Kutzing; Gloeoth-ece rupestris (Lyngb.) Bornet var. minor Jao; Aphanothece saxicola Nageli; Aphanothece castagnei (Breb.) Rabenhorst; Aphanocapsa musicola (Mengh) Wille; Schizothrix lamyi Gamont; Nostoc paludosum Kutzing ex Born et Flahj Stigonema minutum (Ag.) Hass;Stigonema mamillosum (Lyngb.) Ag. ex Born. Six species of them are first reocorded in Jilin Province and one variety are prososed as new to phycological science. In Tundra zone the distribution of these subaeria Cyanop-hyceae are determined by aerial moisture and water content of upper layer of soil.
