OCCURRENCE. — Ashikajima Fm.

DESCRIPTION

Trilete microspore. Amb circular. The laesurae are straight and extend to the 3/4 of the spore radius. The contact area is psilate. Small verrucae, coni and bacula (less than 1 µm long) are sparsely distributed near the equator and on the distal face. The exine is 1 µm thick. Equatorial diameter = 40-45 µm.
