Abstract
Eight strains of Leucosporidium fellii, L. lari-marini, Filobasidium capsuligenum, F. floriforme, and F. uniguttulatum were examined for partial base sequences in positions 492-625 (134 bases) of 26S rRNA and in positions 1451-1618 (168 bases) of 18S rRNA. In the 26S rRNA partial base sequence, there were low maximum homologies (46-58%) among L. fellii, L. lari-marini, and Filobasidium species. In the 18S rRNA partial base sequence, F. capsuligenum had 4 and 5 base differences, compared with F. floriforme and F. uniguttulatum, respectively. Leucosporidium lari-marini and L. fellii showed 0 and 4 base differences with Cystofilobasidium capitatum and L. scottii, respectively. The sequence data obtained were discussed phylogenetically and taxonomically, especially on transferring L. lari-marini to the genus Cystofilobasidium.
