Leptomyxa variabilis Geisen et Burberg, 2016
Diagnosis: Flattened, expanded or comet-shaped cells, moderately branched and never reticulate, 30-150 µm across. Multinucleate, nuclei of vesicular type. Rounded cysts 15-25 µm in diameter.
Ultrastructure: SSU rDNA sequence of the type strain contains signatures TCC GGA CCT TTT AGG starting from position 112 and TTT AGG GAA TTA AGT starting from the position 661.
Differential diagnosis: L. variabilis usually is a comparably small species of the genus Leptomyxa, less ramose and more elongated compared with larger taxa such as L. arborea. However, only molecular signature sequences allow reliable identification.
Ecology: Type location: Roots of Capsella bursa-pastoris, Cologne, Germany.
