SUMMARY Growth requirements of Phoma violacea in comparison with the commoner paint‐attacking fungi Pullularia pullulans and Cladosporium herbarum were determined. In liquid culture media, growth occurred over a range of pH values from 3 to 8, double optimal pH values being noted. A wide range of carbohydrates supported good growth. Lipolysis was not marked. Phoma violacea strains were autotrophic for vitamins. Zinc oxide exhibited fungistatic properties at 5% in agar medium, but was not fungicidal. White lead caused slight fungistasis while titanium dioxide had no marked effect on fungal growth.
