OCCURRENCE. — Ashikajima Fm.
DESCRIPTION
Trilete microspore. Amb rounded triangular with convex sides. The spore is bordered by a thin carina. The laesurae are raised, bordered by a small thickening, and extend to the equator of the spore. Exine cicatricose. The proximal face is tetrahedral and psilate. On the distal face, 3 sets of 4 muri (2 to 4 µm wide, separated by spaces 2 to 5 µm wide) parallel to the equator form equilateral triangles centered on the distal pole, where they delimit a wide triangle (side 15 to 20 µm long) ( Fig. 11 View FIG ). The exine is about 4 µm thick. The ornamentation of this form corresponds to the type I-A defined by Krutzsch (1963). Equatorial diameter = 45 µm.
