Importance and role

Importance of genus to ecosystem

Species of Cercosporidium are foliicolous. They can form leaf spots on surface of leaves and sometimes affect the rate of photosynthesis.


Industrial relevance and applications

The industrial applications of Cercosporidium has not been investigated.


Quarantine significance

The biocontrol properties of Cercosporidium has not been reported.


Biochemical importance of the genus, chemical diversity or applications

The chemical application of Cercosporidium has not been studied. Cercosporidium may produce important enzymes and toxins. This warrants further studies.


Diversity of the genus

Even though there are 66 records of Cercosporidium in Index fungorum (2021), the real number of species is less as many have been synonymized and transferred to other genera such as Cercospora, Clarohilum, Fusicladium, Fusoidiella, Graminopassalora, Mycovellosiella, Nothopassalora, Passalora, Phaeoisariopsis, Pseudocercospora. Cercosporidium comprises 10 species known on several host plants and plant families namely Apiaceae, Apocynaceae, Araceae, Asteraceae, Balsaminaceae, Boraginaceae, Cornaceae, Dioscoreaceae, Euphorbiaceae, Fabaceae, Leguminosae, Nyctaginaceae, Phyllanthaceae, Poaceae amongst others.  Cercosporidium has been reported from Alabama, Algeria, Asia, Brazil, Bulgaria, California, China, Colombia, Cyprus, India, Iowa, Jamaica, Kansas, Mississippi, Nebraska, New Jersey, Ohio, Ontario, Pennsylvania, Tanzania, Venezuela, West Indies amongst others. Comprehensive studies are likely to discover more species of Cercosporidium but DNA sequence data is necessary for species delimitation due to complexity of the genus.
