About 300 specimens (skin scales) obtained from human lesions which previously yielded dermatophytic fungi (Trichophyton rubrum, T verrucosum, T mentagrophytes, and T mentagrophytes var interdigitale) have been newly examined by cultivation. After 6 to 66 months storage in cork-stoppered glass tubes at room temperature these specimens have been recultured on Sabouraud glucose agar medium. The greatest viability has been shown by T verrucosum (growth after 20 months storage). T mentagrophytes has been reisolated after up to 15 months, T mentagrophytes var interdigitale after nine months, and T rubrum after seven months. None of these dermatophytes was able to grow after a period of storage longer than 20 months.
