    Notes: Abstract Portion of the ribosomal repeat of the type strains of the generaExphiala andPhaeococcomyces were subjected to RFLP analysis. The amplicon length of the small subunit rRNA, the fragment NS1-NS24, was found to vary between 1800 to 3200 nucleotides. In contrast, the length of the fragment ITS1-ITS4 comprising the internal transcribed spacers (ITS1 and ITS2) was found to be constant at 600 nucleotides. Analysis of restriction profiles confirmed the synonymy ofExophiala dermatitidis andMycotorula schawii. Torula bergeri andSporotrichum gougerotii were found to be identical toPhaeoannellomyces elegans, but different from their alleged synomymE. castellanii. A phenogram is presented.

    Notes: Abstract Nutritional physiological and tolerance tests were performed for all type strains of species currently classified in the black yeast generaExophiala andPhaeococcomyces, including some additional type strains of taxa recently reidentified asExophiala species. Most describedExophiala species can be distinguished by physiological characters.Exophiala jeanselmei with its varieties, andE. castellanii should all be retained as separate taxa. The pairs of strainsMycotorula schawii/Exophiala dermatitidis, Hormodendrum negronii/Exophiala jeanselmei var.lecaniicorni andSporotrichum gougerotii/Torula bergeri were found to be conspecific. Phenetic analyses of physiological data support the identity ofPhaeococcomyces exophialae as a yeast-like synanamorph ofExophiala spinifera. The taxonomic positions of the generaNadsoniella, Phaeoannellomyces andWangiella are discussed. The generaExophiala andPhaeococcomyces are unrelated.
