Abstract

Numerical classification of 80 strains received as using six different sets of characters was carried out. A set of 57 “differentiating” characters gave six distinct clusters: B, , and (formerly, ). Hence, the strains received as were divided into three subgroups, A, and B. The cluster of was placed apart from the others, and a previous classification of this taxon as a species of was supported by the present study. The problem of a minimum number of differentiating characters necessary for numerical classification, which was considered theoretically as above 40 or 50, was studied experimentally in this study. The results supported the theoretical considerations. Inclusion of linked characters reduced the number of clusters.
