A case of tinea nigra palmaris is reported. A 42-year-old man presented with asymptomatic black macules on his left palm for 15 days. Direct microscopic examination of the lesion showed brownish, branched septate hyphae. Fungal cultures revealed a black yeast-like colony with brown septate hyphae and many chlamydospores under the microscope. It was identi- fied as Hortaea werneckii by sequence analysis of the ribosomal DNA internal transcribed spacer region. The lesions gradually disappeared after topical administration of compound copper sulfate solution and terbinafine hydrochlofide cream.
