    Abstract:
    Phaeosphaeriaceae is a family in the order Pleosporales containing numerous plant pathogens, endophytes, lichenised fungi, and environmental saprobes. A novel genus, Tintelnotia is introduced containing two species, one of which caused an eye infection and several nail infections in humans. All species of Tintelnotia produce conidia in soft pycnidia with a wide ostiole. The generic type species is T. opuntiae causing necrotic spots on cactus plants. The isolates of the human opportunist T. destructans showed variable susceptibility pattern to a panel of common antifungal agents. The MICs of amphotericin B, voriconazole, posaconazole and itraconazole were 1 μg/mL, complemented by an in vitro MEC of 16 μg/mL against caspofungin; the MIC of terbinafine was 0.125 μg/mL. The latter compound contributed to the successful therapy in the ocular mycosis refractory to standard antifungal therapy, the benefit of terbinafine should be highlighted as a therapeutic option especially in difficult-to-treat fungal keratitis.
