C. gloeosporioides mycelium grew well on media with fructose and glucose as carbon source while sorbose and starch promoted sporulation. The mycelia of C. dematium grew well with maltose as carbon source while starch promoted sporulation. Of the nitrogen sources tested, organic nitrogens were beneficial for both mycelial growth and sporulation but chemical nitrogens suppressed both growth and sporulation.
