3,000+, see text Cercospora is a genus of ascomycete fungi.

Most species have no known sexual stage, and when the sexual stage is identified, it is in the genus Mycosphaerella.

[2] Most species of this genus cause plant diseases, and form leaf spots.

It is a relatively well-studied genus of fungi, but there are countless species not yet described, and there is still much to learn about the best-known members of the genus.

It has a cosmopolitan distribution worldwide.
