2017, type species of the genus.
Gram-positive cocci, 1.2-1.5 µm in diameter. Non-motile.
Colonies are milk-white, circular, opaque and convex with entire margins, 1-2 mm in
diameter, on TSA (pH 7). Grows at10- 37 ºC (optimum 28-30 ºC). Growth occurs with
0-4% (w/v) NaCl (optimum 2%).The optimal pH for growth is pH 7.0-8.0. No growth at
pH 5.
Isolated from symptomatic bark tissue of a Populus euramericana canker.
Undetermined. May be involved in Populus euramericana canker.

    family Staphylococcaceae, isolated from symptomatic bark of Populus euramericana canker. Int. J. Syst. Evol. Microbiol., 67, 789-
    794.
Positive results for alkaline phosphatase, catalase, esterase lipase (C8), leucine arylamidase, beta-glucosidase and oxidase.
Acid is produced from D-glucose, D-fructose, aesculin ferric citrate. Weakly positive results for acid production from D-melezitose, D-
turanose and D-lyxose.
Can utilize as carbon sources at 28 ºC (Biolog GP2): dextrin, N-acetyl-D-glucosamine, D-fructose, alpha-D-glucose, maltotriose, D-
mannitol, D-mannose, beta-methyl D-galactoside, alpha-methyl D-glucoside, D-psicose, salicin, trehalose, a-hydroxybutyric acid, alpha-
ketoglutaric acid, D-lactic acid methyl ester, L-glutamic acid, glycyl L-glutamic acid, glycerol, adenosine 2’-deoxyadenosine, D-
galactose,  turanose, L-malic acid, methyl pyruvate, succinic acid, 2,3-butanediol and thymidine.

Negative results for acetoin production, arginine dihydrolase, nitrate reduction, beta-galactosidase, gelatinase, H
2S production, indole
production, lysine decarboxylase, ornithine decarboxylase, tryptophan deaminase, Tween 80, urease, acid production from arabinose,
glycerol and D-mannitol.

Variable results for esterase (C4) and valine arylamidase (negative for the type strain), acid production from trehalose, sucrose and
salicin.
