Gram-positive, irregular rods, 0.5-0.8 / 2.0-2.5 µm, and occurred singly or in pairs with
diphtheroid arrangements; in 5-7-day cultures, they were replaced by coccobacillus
forms, 0.7-0.8 µm in diameter. Non-motile. Non-spore-forming.

Colonies on Corynebacterium Agar are orange to rose-orange, butyrous, opaque,
convex, 1.0 mm in diameter, visible after 2-3 days incubation. Obligately aerobic.
Grows at 24-26 ºC, optimum. No growth at 7 or 37 ºC. No growth in 5% NaCl media.
No growth in 0.03% tellurium acetate.

Isolated from the leaf gall induced by the nematode Anguina graminis on fescue, Festuca rubra L. (Moscow region, Russia).
Resistant to ampicillin, gentamicin, rubomicin and oxacillin. Susceptible to doxycycline, levomicetin, metacycline, rifampicin and
streptomycin.
