Candida parapsilosis (Ashford) Langeron et Talice forms a group of strains which is hard to identify and which, according to present diagnostic criteria, may also include a whole series of strains of related species. Since all these variations are attributed to natural variability, the authors decided to make a detailed study of such strains. It was found that the main cause of strain variability was the generally inexact characterization of this taxonomic group. Ninety morphological, biochemical, physiological and serological unit characters were used as a basis for calculating similarity and distance coeffients. From these coefficients, a dendrogram was constructed, which showed the existence of natural groups and indicated that some of the strains were originally incorrectly identified, owing to incompleteness of the criteria of traditional taxonomy. A group of 10 strains corresponding to the original description formed the phenon 87, with a mean similarity level of 87%. This included three strains with approximately the same centroid value, forming a group corresponding toCandida parapsilosis in sensu strictu in the meaning of older taxonomic criteria. This group is described in detail in the text. In addition to this group, very similar strains and a number of intermediate forms were found. These included some strains whose characteristics corresponded to more recently identified species, such asCandida obtusa, Candida lusitaniae, etc.

Varieties originally described asCandida parapsilosis var.intermedia orCandida parapsilosis var.quercii were included in the speciesCandida tropicalis, or were classified as intermediate forms betweenCandida parapsilosis andCandida tropicalis.
