Genus Dracomyxa Hülsmann, 2014
Diagnosis: Large plasmodia with hundreds or thousands of small nuclei involved in bidirectional streaming. Obligatory alternation of sessile and motile stages. Locomotion by migration via one or several giant pseudopodia with pre-dominantly unidirectional centrifugal streaming of protoplasm. Cyst formation. Tectum as (protective) covering. Occasional formation of protoplasmic propagules (blisters, blebs) from pseudopodia and central areas. Omnivorous or predatory. Occurring in freshwater habitats.
Cell body vermiform or reticulate, usually large (up to several centimetres in diameter), either covered by smooth inconspicuous tectum or completely naked during and after migration. If present, tectum opens with pseudostomes, usually located terminally. Bulky aggregates of defecation particles accumulate along basis of pseudopodia emerging from pseudostomes. No cleansing process before migration. Cysts in rows inside tectum, singular, pediculate. Predatory.
