Bensingtonia

Vegetative cells of Bensingtonia sorbi, from Wang et al. (2003). Scale bar = 10 µm.

Belongs within: Uredomycetidae.

Bensingtonia is a genus of yeasts characterised by the production of ballistoconidia and the presence of the Q-9 ubiquinone.

Characters (from Boekhout & Nakase 1998): Cells ellipsoidal, ovoidal or elongate. Budding mostly polar, with buds sessile or on short denticles, enteroblastic, with percurrent or sympodial proliferation. Ballistoconidia bilaterally symmetrical, straight or curved, apiculate, ellipsoidal, ovoidal, amygdaliform, falcate, allantoid or reniform. Colonies whitish, cream, pale pink, brownish-yellow (ochre), brownish or grayish-red. True mycelia and/or pseudomycelia may be present. Septal pores simple. Clamp connections absent. Fermentation absent. D-Glucuronate and nitrate may be assimilated; myo-inositol not assimilated. Diazonium blue B and urease reactions positive. Xylose absent from whole-cell hydrolyzates. Major ubiquinone is Q-9.
