A species of Cladosporium was isolated from an air conditioner outlet in a hospital in Taipei. Based on the morphology, cultural characteristics, and phylogenetic analysis of sequences of the internal transcribed spacer (ITS1-5.8S-ITS2) of the rRNA gene and translation elongation factor 1-alpha (EF1α) gene, this strain was identified as Cladosporium pulvericola. It is a new record for Asia. Morphological and cultural characteristics are illustrated and described.
