Phoma is arbitrarily limited to those species in which the spores are less than 15 µm as the larger spored forms have been placed in the genus Macrophoma. The most important species include Phoma beta which is the cause of the heart rot and blight of beets, Phoma batata that produces a dry rot of sweet potato, and Phoma : Dothideomycetes.

Phoma. Phoma is a genus of fungal organisms that is widespread throughout the world – its species are commonly found in soil, organic matter, plants and also in aquatic environments. Many species of Phoma are important plant pathogens, known to contaminate food sources such as maize and potatoes.

Furthermore, several species can be pathogenic to animals and humans. Phoma is a highly polyphyletic genus with its unclear species boundaries.

The conventional system of identification is functional but it has its limitations. Besides morphological studies, chemotaxonomy, secondary metabolite and protein profiling have been assessed Cited by: Phoma is a genus of fungi within the Coelomycetes.

Phoma is a polyphyletic genus of fungal organisms belonging to the phylum Ascomycota, class Dothideomycetes, order Pleosporales, and family Didymellaceae, as depicted in Figure 1 [1,2,3].

Phoma spp. was conceptualized in the 19th century by Italian mycologist Pier Andrea Saccardo (), and almost years later updates were made to the definition and classification of the genus by Gerhard.

About this book. Fungal taxonomists routinely encounter problems when dealing with asexual fungal species due to poly- and paraphyletic generic phylogenies, and unclear species boundaries.

These problems are aptly illustrated in the genus Phoma. Description This book is a practical manual to aid identification of Phoma species, and will be useful for researchers working in the areas of mycology, plant pathology and microbiology.

It provides line drawings and keys for the identification of specific and infraspecific taxa of Phoma, including common pathogenic and saprophytic species, with references to additional diagnostic.Phoma Sacc. emend. Boerema and G.J. Bollen () is an ubiquitous genus, which has been reported from plants, soil, human beings, animals and air.

The speciation of the genus Phoma was based on host-alone and later on, the trend was to study different species of Phoma in pure culture.Phoma: (fō'mă), A genus of rapidly growing fungi that are common laboratory contaminants and common plant pathogens; rare cause of infection in immunosuppressed patients.
