Abstract

A novel species of ascomycetous yeast, sp. nov., is described from necrotic tissue of columnar cacti on Caribbean islands. is closely related to and phenotypically very similar to and There are few distinctions between these taxa besides spore type, host preference and locality. Sporogenous strains of that produce asci with four hat-shaped spores have been found only on Curaçao, whereas there was no evidence of sporogenous from that island. In addition, sequences of the D1/D2 fragment of the large-subunit rDNA from 12 Curaçao strains showed consistent differences from the sequences of the type strains of and . The type strain of is TSU00-106.5 (=CBS 11169 =UCD-FST 09-160).
