Phoma is a genus of the asexual stages of fungi. It contains many plant pathogenic species.
Spores are colorless and unicellular. The pycnidia are black and depressed in the tissues of the host. Phoma is arbitrarily limited to those species in which the spores are less than 15ų as the larger spored forms have been placed in the genus Macrophoma. The most important species include Phoma beta which is the cause of the heart rot and blight of beets, Phoma batata that produces a dry rot of sweet potato, and Phoma solani. [2]
