β hemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony.

Culture types of agar plates.

Before you can transfer and store mushroom cultures on agar you need properly made nutrient rich agar plates. On solid media a single microbe will grow and divide to produce a colony a spot of identical descendants.
