It is a highly differential medium that is used for demonstrating mor-
phological and biochemical reactions characterizing different Candida
species. Candida albicans appears as blunt conical colonies with
smooth edges and yellow to blue-green color. Candida stellatoidea
appears as convex colonies with smooth edges and yellow to green
color. Candida tropicalis appears as convex colonies with wavy edges
and yellow-green to green color with a dark blue-green base. Candida
pseudotropicalis appears as convex, shiny colonies with smooth edges
and green color with a light green edge. Candida krusei appears as low
conical colonies with spreading edges and blue-green color. Candida
stellatoidea appears as convex colonies with smooth edges and yellow
to green color.
