ORIG DESCRIPTION
*
Two-celled spore, 7.7 x 12.6 µm, cells of unequal size, round to subspherical, walls overlap at boundary to form disk-shaped septum. Potential thin-walled germinal pore in terminal end of smaller cell, wall 0.5 µm thick.
COMMENTS
*
The spore is similar in shape and dimensions to Shortensis memorabilis, Order Microthyriales, Family [Subfamily] Stomiopeltoideae, Dilcher (1965, pl. 20, figs. 157-159). The present material, however, does not show a hyaline sheath nor lighter pigment in the smaller cell. The potential germinal pore is not recorded for Shortensis memorabilis but Dilcher did note on p. 30, that "the small hyaline cell of the spore develops into the initial hyphal cell which produces a terminal hypha and an obliquely disposed lateral hypha in opposite directions (pl. 21, fig. 161)".
