SPECIES, AUTHORITY S. shahejiensis Elsik 1990a, p. 164.
LOCATION Shahejie Formation, Leowning Province, China.
ORIG DESCRIPTION* Aseptate, psilate fungal spores. Spore outline elliptical with bluntly rounded ends. One furrow oblique to the axis of the spore, straight for most of the length of the spore except for near the ends where it wraps sharply around the sides of the spore. Overall size ca. 16 x 28 µm. Spore wall ca. 0.8 µm thick.
COMMENTS* Spirotremesporites shahejiensis is unique in the character of the broadly rounded ends of the spore caused by the distinctly elongated sigmoidal shape of the furrow. The morphology of the spore is distinct.

Derivation: Named for the rock strata in which it occurs.
