Perfect state of Rhodomyces dendrorhous ( Phaffia rhodozyma )

After mother–daughter cell conjugation, formation of long holobasidia with terminal basidiospores was observed without mycelium production in Rhodomyces dendrorhous (including the type strain of Phaffia rhodozyma ) on polyol‐containing media. Basidiospores are not forcibly discharged and germinate by budding. A new genus Xanthophyllomyces (Filobasidiaceae, Tremellales) with a species, X. dendrorhous , is proposed for the telemorphic state of R. dendrorhous .
