The species diversity and identification of black fungi belonging to Cyphellophora and Phialophora, which colonize and infect human skin and nails, were studied using amplified fragment length polymorphism (AFLP). A total of 76 Cyphellophora and Phialophora isolates were evaluated, and their delimitation was compared to earlier studies using multilocus sequencing. The results of the AFLP analysis and sequencing were in complete agreement with each other. Seven species-specific padlock probes for the most prevalent species were designed on the basis of the ribosomal DNA internal transcribed spacer region, and identification of the respective species could easily be achieved with the aid of rolling circle amplification.
