Phaeohyphomycosis is caused by a heterogeneous group of mycelial dematiaceous (phaeoid) fungi, which produce melanin pigment. This condition is often confused with chromoblastomycosis. Rhytidhysteron is a dematiaceous fungus, which has been recently found to be causing human infections. Till date only three cases of infection with Rhytidhysteron rufulum have been reported in the literature. All three cases have been from North India. Hereby, we present another two cases where Rhytidhysteron was isolated. Both the patients belonged to Chandigarh (India) and presented with subcutaneous lesions. The isolates were confirmed by ITS sequencing. Both the patients were immunocompetent and gave no history of trauma or any other predisposing factor. Phaeohyphomycosis are often missed due to lack of knowledge regarding the fungi causing the infections and there is need for clinical, pathological and microbiological correlation for effective diagnosis and treatment in these cases.
