Guide to Encyonema hamsherae

The dorsal margin is arched, while the ventral margin is slightly convex to somewhat flat in smaller specimens. Apices are protracted and slightly capitate. Striae are radiate in the center valve, becoming nearly parallel at the apices. Central striae on the ventral side are often somewhat bowed. The dorsal stria density is usually greater than the ventral stria density by 1 or 2 in 10 µm.
