Lateromyxa gallica
Lateromyxa gallica – from Hülsmann

Lateromyxa gallica Hülsmann, 2007

Diagnosis: uni- or multinucleate vampyrellid amoebae from 25-800 µm in diameter, with one to multiple nuclei, pseudopodia usually tapering and rising from anterior margins of locomotive cells. Move from cell to cell of Oeodogonium through lateral walls, forming ‘pseudocyst’ in the process. With one species (L. gallica).

Remarks: Lateromyxa gallica has been isolated several times from two lakes in central France between September 1973 and August 1989 and cultivated for several months or years under laboratory conditions. No essential variations of feeding behavior were found over the time; all isolated strains invade the trichomes of the green alga Oedogonium and move, divide and encyst inside the vanished plant cells. Penetration is performed by attacking the cross walls and only primary attacks are directed against the lateral cell walls of the algae. These findings contrast with the behavior, life cycles and fine structure of all known species of the genera Vampyrella, Hyalodiscus, Arachnula and Gobiella (Hülsmann, 2007).
