Lecture No.4

Study of fungi:
Specimens are studied in one of the two ways: those that cannot be grown under artificial conditions are studied directly, and those that must or can be cultured or isolated are studied indirectly.

1-Indirect study:
Many pathogens in plant material, soil and water must first be isolated and obtained in pure culture before they can be studied. These fungi are usually not visible to the unaided eye, although the disease symptoms often are.
