Phoma spp.


The organism, Phoma spp., is a member of the coelomycete (EmLab P&K) fungi that produce spores inside a pycnidia.  The spores are produced inside this hollow structure with an opening on top in an arrangement similar to a kiwi fruit or a pomegranate.

In buildings, this organism will often grow on slab on grade carpet with moisture problems.  It is a plant pathogen in tropical to temperate climates.  The single celled spores are unremarkable in structure and not differentiated on Air-o-cell cassette samples. The organism is may be allergenic. 

The organism grows best on media with higher water activity such as MEA.  It does not grow well on DG-18.
