Phoma betae / herbarum Background Info:
Phoma is a very common soil fungus attacking weak or damaged plants. It is frequently isolated from different soils, dead plant tissues and potato. Phoma is frequently found indoors as a contaminator of humid surfaces, especially in connection with biodeterioration of painted walls, producing coloured spots, often pink of purple, several centimetres in diameter.

Phaeohyphomycosis is a mycotic disease caused by dematiaceous fungi that produce brown yeast-like cells, pseudohyphae, and irregular true hyphae in tissues. Seven Korean cases of subcutaneous phaeohyphomycosis have been reported to date, ranging in age from 9-84 years. Causative organisms of subcutaneous phaeohyphomycosis were 3 of Exophiala jeanselmei, 2 of E. dermatitidis, 1 of Drechslera dematioidea and 1 of Phoma sp. Four cases of abscess and 3 cases of verrucous plaque were present as skin lesions, and were all exposed areas of the body. (Suh 2005 ref.25667 5)
