Importance and role
Importance of genus to ecosystem
Species of Cercostigmina are plant pathogenic showing as leaf spots on various hosts.
Industrial relevance and applications
The industrial applications of Cercostigmina has not been investigated.
Quarantine significance
The biocontrol properties of Cercostigmina has not been reported. Cercostigmina may have potential to control some pathogens. Further studies are needed.
Biochemical importance of the genus, chemical diversity or applications
The chemical application of Cercostigmina has not been studied. This warrants further research.
Diversity of the genus
Although there are 18 Cercostigmina epithets in Index fungorum, the real number of species is less as most of the species have been synonymized and transferred to other genera namely Mycosphaerella and Pseudocercospora. Cercostigmina comprises three species known on several host plants such as Apocynaceae, Asparagaceae, Fabaceae, Meliaceae, Myrtaceae, Proteaceae and Rutaceae. Cercostigmina has been reported mainly from Australia, New Jersey, South Africa, Ukraine and Utah. The diversity of Cercostigmina is still poorly studied and extensive studies are required for more species discovery.
