Exophiala


Exophiala

(ek'sō-fī'ă-lă), A genus of pathogenic fungi having dematiaceous conidiophores with one- or two-celled annelloconidia. They cause mycetoma or phaeohyphomycosis; in cases of mycetoma, black granules develop in subcutaneous abscesses; in cases of phaeohyphomycosis, hyaline or brownish hyphae are found in tissues. [exo + G. phialē, a broad flat vessel]

Exophiala

A genus of imperfect fungus with no known sexual state. Colonies are initially yeast-like, moist, and brownish to greenish black. The texture becomes velvety due to short, aerial hyphae. The front colour is olive-black; the reverse is black in mature colonies. Exophiala may cause mycetoma and chromoblastomycosis after traumatic subcutaneous inoculation in a background of local or systemic immunosuppression, such as organ transplantation. Other sources of infection include prosthetic valve vegetations, fungemia and systemic infection.
