|Description:||After a 21 day incubation period, this Petri dish culture plate produced a large colony of Phoma sp. fungal organisms. Note the texture of this colony, described as powdery, or velvety in appearance, exhibiting a characteristic white, at times olive gray, to pinkish-beige coloration.|
Though uncommon, Phoma sp. are sometimes a cause of the fungal disease, phaeohyphomycosis, usually in individuals who are immunosuppressed, and may be confined to the cutaneous tissues, or rarely, systemically disseminated. Phaeohyphomycosis is of a group of fungal infections characterized by superficial and deep tissue involvement caused by dematiaceous, dark-walled fungi that form pigmented hyphae, or fine branching tubes, and yeast-like cells in the infected tissues.
