The genus Fonsecaea comprises etiologic fungal agents of human chromoblastomycosis (1-3), a chronic cutaneous and subcutaneous infection characterized by slowly expanding nodules that eventually lead to emerging, cauliflower-like, mutilating and disfiguring eruptions.
Fonsecaea contains anamorphic ascomycetes belonging to the family Herpotrichiellaceae (order Chaetothyriales), which includes black yeasts and relatives (10-12).
We studied 81 isolates representing the 3 currently recognized Fonsecaea spp.

Rosen cultured it and grew out Fonsecaea pedrosoi, a soil fungus that is rare in the United States and usually seen in Central American agricultural workers.
For relatively mild cases of Fonsecaea infection, itraconazole is a good choice, Dr.
Fungi tested included Aspergillus, Candida, Cryptococcus, Fusarium, Mucor, Bipolaris, Cladosporium, Penicillium, Sporothrix, Beauvaria, Fonsecaea

Tertiary care centers like Baylor are reporting increases in fungi such as Cryptococcus, Histoplasma capsulatum, Sporothrix, Fusarium, Rhizopus, and Fonsecaea
, which often go unrecognized or misdiagnosed for a long time.
Many fungi cause chromoblastomycosis, but it is most often caused by Fonsecaea
pedrosoi, followed by Cladophialophora carrionii and Phialophora verrucosa, said Arnaldo Lopes Columbo, Ph.
