BioImagesBioImages (www.bioimages.org.uk) has 15 images of Phoma (a form genus of coelomycetes)

The commonest form-genus of coelomycetes, Phoma form black medium thickness-walled, erumpent pycnidia on (usually) dead stems (occasionally leaves). The pycnidia produce simple conidia generally less than 15µm long, on short or imperceptible conidiophores. The conidia often contain two oil-droplets.

Many of the species are host limited (or at least there are different names which have been applied to Phoma on different hosts).

Phoma has been used as a taxonomic dumping ground for any coelomycete with simple hyaline spores.

Coelomycetes with medium thickness walled, erumpent pycnidia and simple, hyaline conidia generally less than 15µm long, on short or imperceptible conidiophores. Mostly on dead stems.

The similar Phomopsis produces slightly larger and tougher pycnidia but is best distinguished by the longer conidiophores.

Phyllosticta, with thinner walled pycnidia, is the equivalent on leaves.

Cultural studies are needed to identify most spp.
