In order to study the effect of carbon originating from different sources on the growth of P. citrophthora, a modified Christie's formula was used as the basic nutrient medium. Carbon in various forms was then substituted for glucose in equivalent amounts. The fungus grew to a limited extent on glucose as the carbon source, but grew quite well on a maltose medium and less extensively on a sucrose medium. Fungus growth was most profuse on soluble starch, even more so than on potato dextrose and oatmeal medium. No sporangia were found in any of the media. © 1972 Kluwer Academic Publishers.
