SPECIES, AUTHORITY A. capitata Srivastava 1976, p. 97, pl. 2, figs. 10-11.
LOCATION Osmington Mills, Dorset, England.
ORIG DESCRIPTION* Spherules or coccoid cells, 0.5 µm to 1.5 µm in diameter, outline circular, sometimes diplococcoid, occurring individually, in pairs or in rows. Occasionally, the rows of spherules are very much near each other and give an impression of clustering. Surface of the host cell degrades around the spherules, leaving pits. Small bacillary hyphae develop a beaded structure and eventually produce spherules, with the hyphae disintegrating after the spherules mature. Finally, the spherules are shed from the host cell by degradation of the substratum, leaving pits on the host cells.

Etymology: from Latin, capitatus, with head.

K&J REMARKS The spherules were found on the surface of a Jurassic specimen of Exesipollenites tumulus. The pits on corroded spores may be the result of growth of bothroid pyrite spherules. Jansonius & Hills (1977, card 3294) interpreted the spherules as "glomerules" or "Ubisch bodies," which are produced by the tapetum, and occur commonly on a number of gymnospermous pollen.
