Exophiala

Exophiala is a genus of anamorphic fungi in the family Herpotrichiellaceae. The widespread genus contains 28 species. The genus was formally described by J. W. Carmichael in 1966.

Exophiala has been implicated in causing 'saxophone lung' or hypersensitivity pneumonitis, a disease that can be contracted by woodwind instrumentalists (saxophonists, clarinettists, oboists, etc.). A case study presented at the annual meeting of the American College of Allergy, Asthma and Immunology highlighted that it is possible to develop this allergic pulmonary disease through improper cleaning of instruments.

Exophiala werneckii is the organism responsible for tinea nigra.

Some sources equate Hortaea werneckii, Cladosporium werneckii, Exophiala werneckii, and Phaeoannellomyces werneckii.

Exophiala jeanselmei causes maduromycosis. This is usually an asymptomatic disease which presents with black or brown macular lesions which enlarge by peripheral extension. The lesion is darkest at the periphery and has very distinct margins. Lab diagnosis- using a KOH mount. Typically seen is brown septate branching hyphae or dark brown budding cells. Treatment is topical antifungal: miconazole or econazole.
