From Williams et al., 2017:

Acritarch genus, according to Stover and Evitt, 1978, and Fensome et al., 1990

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Drugg and Loeblich, 1967]:
Description:
Flask-shaped cyst, more or less elliptical in outline, with an aperture at the apex. Wall two-layered, endophragm relatively thick and rigid, periphragm thin and filmy. Periphragm tends to adhere to endophragm "dorsally" and "ventrally" but remains free and bag-like around the circumference.
