Gram-negative rods, 0.5-1.0 x 1-3 µm. Motile by peritrichous flagella.

Colonies are generally mucoid, domed and can vary in color from white to cream.
Optimum growth temperature 26 - 30 ºC. No growth at 40 ºC. Facultatively anaerobic.

Isolated from plants.

Causes a vascular wilt (watermark disease) of Salix species.
