Importance and role

Importance of genus to ecosystem

Species of Chaetophoma are saprobic and helps in decomposition of organic matter in the ecosystem. Some taxa might be endophytic and contribute to plant health.


Industrial relevance and applications

The industrial use of Chaetophoma has not been investigated,


Quarantine significance

No disease has been reported from Chaetophoma.


Biochemical importance of the genus, chemical diversity or applications

The chemical diversity of Chaetophoma has not been investigated.


Diversity of the genus

Even though there are eighteen Chaetophoma epithets in Index fungorum, the real number of species is less as six species have been synonymized and transferred to other genera such as Chaetasbolisia, Chaetophomella, Cicinnobella, Lasiophoma, Melanops and Phomyces. Chaetophoma comprises twelve species known on wide range of hosts such as Chamaecyparis thyoides (Cupressaceae), Fraxinus excelsior (Oleaceae), Glycine max (Fabaceae), Metrosideros collina (On leaf surface) (Myrtaceae), Myrcia tomentosa (Myrtaceae), Phalaris arundinacea (Poaceae), Prunus ×yedoensis (Rosaceae), Syngonium auritum (Araceae), Viburnum awabuki (Caprifoliaceae) amongst others. Chaetophoma has wide geographical distribution such as Argentina, Brazil, California, Hawaii, Japan, Mexico, New Jersey, Papua New Guinea, Paraguay, Poland, Ukraine, West Indies amongst others. The diversity of Chaetophoma is still poorly understood and understudied hosts and regions must be further explored to discover new species of Chaetophoma.
