Some members belonging to black Aspergilli are widely used for manufacturing “Imo-Shôchú, ” or sweet potato distilled wine, in the southern districts of Japan, such as Kagoshima and Lûchû islands. Among these strains five species have hitherto been reported; i.e. Asp. luchuensis Inui, Asp. batatae Saito, Asp. awamori Nakazawa and its varieties, Asp, aureus Nakazawa and its varieties, and Asp. miyakoensis Nakazawa. In April to July, 1935, the authors visited almost all brewers, i.e. 189 brewers, located in those districts above mentioned, and collected 435 samples from Kuro-Kôji, or mouldy material, fermenting mash and soils of the factories, and isolated from them about three hundred different strains of black Aspergilli. All the strains isolated by the authors are quite different from ordinary Asp. niger in the characteristics of the conidial wall surface, which in the former case showed somewhat rough appearance or was even perfectly smooth, while it was distinctly echinulate or with coloured bars, as mentioned by C. THOM, in the latter. The isolated strains, including five new species and five new varieties, along with the hitherto known species may be classified as in the Key shown above.
