sporinite

n
a liptinite maceral exhibiting various lenticular, oval, or round forms that reflect the cross-sectioning of a flattened, hollow, ovoid body; sometimes exhibits rod-like projections that are small relative to the size of the total body.
DISCUSSION — Sporinite originated as a lipid substance that covered, as a skin, ovoid spore or pollen grains which commonly ranged from around ten to several hundred micrometres in diameter. Sporinite often occurs as fragments derived from these initially ovoid bodies.
