Bulleribasidium Sampaio, Weiss & Bauer (2002)

In the determination of the asexual reproduction of Bulleribasidium, it is seen that the yeast cells are ovoid and budding is polar. Ballistoconidia are formed and are rotationally symmetrical. Cultures are yellowish-cream in color. In sexual reproduction it is found that the sexual structures are formed in the filamentous state. The hyphae have incomplete clamp connections but form haustorial branches. The sexual state is only observed in culture, and basidiocarps are not formed. Basidia are typically transversely septate and occasionally longitudinally septate and are arranged in small clusters or occur in isolation. The basidiospores are produced at the apex of tubular sterigmata and are forcibly discharged. They are globose, rotationally symmetrical, and germinate by budding or repetition. The septal pore is a dolipore with poorly developed parenthesome-like elements. The chapter also discusses physiology/biochemistry and phylogenetic placement of the genus. The type species taken is Bulleribasidium oberjochense. The salient features of Bulleribasidium are the formation of a transversely septate and two-celled basidium, combined with the formation of ballistoconidia in the yeast state. A Bulleribasidium-like life cycle might be hypothesized for the closest asexual relatives of B. oberjochense presently classified in Bullera. © 2011
