Morphology Dermatophilus congolensis
CELLULAR  
Staining Gram-positive Not acid fast
Morphology Aerial mycelium develops in atmospheres containing added CO2. Substrate mycelium consists of long tapering filaments, branching laterally at right angles; septa formed in transverse and in horizontal and vertical longitudinal planes, giving rise to up to eight parallel rows of coccoid cells (spores),
Motility spores are motile by a tuft of flagella..
