Examples from the Web for oocyst
No sporozoites are formed in the oocyst, the sporozoites being unenclosed (gymnospores).
The order Coccidiidea is divided into four families, characterized by the number of sporocysts (if any) found in the oocyst.
In one case (Coccidium mitrarium), the oocyst itself, instead of being spherical, is curiously shaped like a mitre.
Immediately after the formation of the antheridia new productions show themselves, both around the oocyst and within it.Fungi: Their Nature and Uses|Mordecai Cubitt Cooke
