A mucron is present

Syzygy does not occur.

The gamonts are composed of a single structure without septa: they lack both protomerites and deutomerites.

Anisogamy — unequal sized gamonts — is present. Gamogony occurs with gamonts still attached to intestinal wall. The gametes bud off gamonts. Gametocysts are absent

There is no sporocyst.

The zygote gives rise to 10–16 oocysts.
