Diagnosis Hydroid solitary, with hollow filiform tentacles, but often moniliform distally, in one whorl under hypostome; lower part of hydranth with simple pedal disc, no perisarc except on encysted embryos.. Without medusa phase or gonophore development, eggs and sperm developed directly in epidermis of polyps in wart-like protuberances; asexual reproduction by lateral buds, leading only to temporary colonies [details]
