Gram-positive, nonmotile ovoids, typically occurring in pairs or long chains.
Anaerobic growth for 24 h on sheep blood agar produces flat, shiny, off-white, round,
alpha-hemolytic colonies, 2 mm in diameter. Facultatively anaerobic.
Grow in the presence of 40% bile and 0.016% potassium tellurite, but not 6.5% NaCl.
