The first case of human disease due to the thermophilic ascomycete Thermoascus taitungiacus (the teleomorph of Paecilomyces taitungiacus) is presented. T. taitungiacus was recovered from four dialysate fluid specimens of a 57-year-old patient undergoing chronic peritoneal dialysis. Identification was based upon cylindrical conidia, reddish orange nonostiolate ascomata, lack of growth at 20°C, thermotolerance, and ascospores that appeared pale yellow, elliptical, thick walled, and predominately echinulate by light microscopy but irregularly verrucose by scanning electron microscopy.
