Phoma

Phoma is a genus of common coelomycetous soil fungi. It contains many plant pathogenic species. About 140 Phoma taxa have been defined and recognized which may be divided into two large groups: (i) plurivorous fungi, generally saprobic or weakly parasitic, mainly from temperate regions in Eurasia, but occasionally also found in other parts of the world (including areas with cool or warm climates); and (ii) specific pathogens of cultivated plants.
