Xanthophyllomyces sp. was isolated as an epiphytic red yeast from leaves of Eucalyptus glo-bulus in Concepción, Chile. Sexual reproduction was by basidiospores produced from one or rarely two metabasidia arising from a yeast cell without preceding paedogamy. The main carotenoid pigment was astaxanthin. This isolate did not cluster with the X. dendrorhous complex (including Phaffia rhodozyma) in ITS and 26S rDNA-based phylogenetic analyses. The phylloplane may be a further habitat for Xanthophyllomyces, in addition to the well-known spring sap-flows of deciduous trees and the recently-characterised ascostromata of Cyttaria hariotii.
叶黄素酵母属（Xanthophyllomyces sp.）是从智利康塞普西翁的蓝桉树叶中分离得到的一种附生红酵母。有性生殖通过担孢子进行，担孢子由酵母细胞产生的一个或极少情况下两个后担子产生，之前没有幼体配合。主要类胡萝卜素色素是虾青素。在基于ITS和26S rDNA的系统发育分析中，该分离株未与红酵母复合体（包括红法夫酵母）聚类。除了众所周知的落叶树春季树液流动和最近鉴定的哈里奥蒂孢裂菌子囊座外，叶表面可能是叶黄素酵母属的另一个栖息地。
