1. The geographical distribution of Allomyces in northeastern Japan has been investigated since 1947,and the results are briefly abridged herein. 2. 12 localities of Allomyces arbuscula BUTLER, All. neo-moniliformis INDOH, and a strain of All. javanicus KNIEP var. japonensis INDOH, besides an undetermined species of the same genus were found in parts of Iwate, Yamagata and Akita Prefectures. Among the named species, All. arbuscula was the most widely distributed one, being found at nine-localities. 3. This genus which has never been found in regions north of the vicinity of Akita City, possesses species which distributed rather continuously in the paddy fields cultivated in the interior land regions. 4. The geographical distribution of Allomyces, especially its northern limit, seems to be governed by the annual average temperature, which in the vicinity of Akita City is 10.5℃. 5. In Europe, North America and Japan, the northernmost limit in the geographic distribution of the genus corresponds to latitude 40°North. This position in both North America and Japan agrees with the northern limit of moderate continental forest climate ; mild winters(Cfa)of the classification presented by KOPPEN.
