Clavispora, a new yeast genus of the Saccharomycetales

Antonie Van Leeuwenhoek. 1979;45(3):479-83. doi: 10.1007/BF00443285.


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.
