1) The author isolated 1010 strains of molds from the mildew on bamboo through two years from December 1955 to November 1957,and a pair of months was taken as a unit of period for investigating the seasonal variation in the number of the isolated molds and the state of stains produced by them.2) The molds grew on the bamboo in the following order of intensity, but from December to March, no growth of molds was observed : 53.7% June and July (rainy season >28.4%, August and September>10.5%, April and May>7.4% October and November.3) Among the fourteen genera, the following ones were frequently isolated and developed much more vigorously than the others. The occurred in a decreasing order of precentage : Cladosporium sp.26.0%>Alternaria sp.18.0%> Aspergillus sp. 11.7%> Pullularia sp. 10.9%> Penicillium sp.8.7%.4) The five genera mentioned above damaged the substrate remarkably. Above all, Cladosporium sp., Alternaria sp. and Pullularia sp. leave spots on the substrate even after washing with water.
