The genus Tyzzeria Allen, 1936 consists of coccidia whose oocysts are without sporocysts, each oocyst possessing eight sporozoites (although the sporozoites are surrounded by a thin membrane). Species occurring in Anseriforme birds appear to be valid whereas the others appear to be misidentifications.
