A micrograph revealing histopathologic changes in phaeohyphomycosis due to Exserohilum rostratum, 1980. 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.
