Carbohydrate patterns of Candida, Cryptococcus and Rhodotorula species.

Within the genus Candida three distinct groups are recognized on the basis of carbohydrate patterns of intact whole cell hydrolyzates. In the first, ascomycetous, group mannose is dominant, while rhamnose, fucose and xylose are absent; this is indicative of an affinity with endomycetous families. Among the basidiomycetous representatives, two groups can be recognized. One group is usually characterized by the presence of xylose and has a low mannose content. The pattern is typical for Cryptococcales and Tremellales (e.g., Cryptococcus, Trichosporon, Bullera and Tremella). The other basidiomycetous group is characterized by the presence of fucose and/or rhamnose with significant amounts of mannose. This pattern is characteristic for Sporobolomycetaceae.

The yeast Candida sequanensis sp. nov.

A strain of an undescribed Candida species was isolated from animal fodder. A description of the new species is given and its distinction from the most closely resembling species of the genus is discussed.

Xylose distribution within and taxonomy of the genera Bullera and Sporobolomyces.

All CBS strains of the ballistosporic genera Bullera and Sporobolomyces were screened for the presence of xylose by means of gas-liquid chromatographic analysis of derivatized whole-cell hydrolysates. Xylose was found in the majority of Bullera strains, whereas it was mostly absent from Sporobolomyces. The results do not suggest the necessity of any changes in the present concepts of both genera.

Clavispora, a new yeast genus of the Saccharomycetales.

In Candida lusitaniae van Uden et do Carmo-Sousa (1959), strains of opposite sex have been found. Cells of the opposite mating types conjugate and form asci with one to four clavate spores. These are easily liberated from the ascus. The type strain of Candida obtusa (Dietrichson) van Uden et do Carmo-Sousa ex van Uden et Buckley (1970) also produces ascospores after mating with one of the strains of Candida lusitaniae. As clavate ascospores are unknown in yeasts, a new genus, Clavispora, is proposed with Clavispora lusitaniae spec. nov. as type species.

A new genus: Sporopachydermia.

In two species of the yeast genus Cryptococcus ascospores have been found. A genus is described to accommodate the two species, because the spore wall is extraordinarily thick and its ultrastructure differs from that found in all other yeast genera. The spores are easily liberated from the ascus at maturation. The name Sporopachydermia is proposed for the genus and the names S. lactativora and S. cereana are proposed for the species.

Two new species of the genus Sterigmatomyces.

The descriptions of two new species of the genus Sterigmatomyces, St. nectairii and St. penicillatus are given. The diagnosis of the genus is extended to starch production, positive or absent. An earlier described species, St. acheniorum Buhagiar et Barnett, is transferred to the genus Rhodotorula.
