The classification of the genus Ammonia in species is controversial. While several different forms exist, many authors consider the genus to consist of a single species, Ammonia beccarii, with many ecophenotypes. However, recent molecular studies revealed that the genus consists of many species, although they may be difficult to discriminate based on morphology.[2]
Based on a comparison between molecular results and morphology, the following species appear to be valid:
Additionally, several other molecular types have been discovered that do not match any of the described species and thus possibly represent new taxa.[2]
