Aspidopora
Aspidopora newberryi. SMH collection
Aspidopora sp. in oblique (left) an longitudinal (right) sections. Field of view is 1.5 mm. CMC 2952.
Aspidopora colonies are thin discs. Zooecia are circular to subelliptical, and they are nearly separated by mesozooids bearing numerous diaphragms in outer exozone. Cystiphragms are common, but diaphragms are rare to absent. Tiny styles are present.
Astrova (1978) considered Aspidopora to be a synonym of Prasopora, but Karklins (1983) retains it as a separate genus.
