SPECIES, AUTHORITY B. ovoidus Song Zhichen & Cao Liu 1994, p. 41, pl. 1, fig. 22.
LOCATION King George Island. Antarctica.
ORIG DESCRIPTION* Spores elongated ovate or vase-shaped, distal end broadly round, gradually tapering toward the proximal end, proximal end flat; holotype 45 µm in length, widest part 22 µm in width, narrow end about 7 µm in width, four- to five-celled, contact areas between cells without distinct indentation. Septa thick, discoidal, without septal folds; spore wall about 1.5 µm in thickness, surface smooth, black.
COMMENTS* This new species is characterized by its spores tapering toward the basal end, and its proximal cell being shallowly trapezium-shaped, its lack of extension or curvature, which differentiate it from Brachysporisporites antarcticus and B. grandus. Similar specimens have been found in Tertiary strata in South Argentina, but those specimens are smaller in size, and 36 µm in length.

Etymology: for almost ovate shape.
