Pythium debaryanum

Pythium debaryanum is a species of water mould in the family Pythiaceae. It is known as a plant pathogen on many kinds of wild and cultivated plants, including peanut, beet, eucalyptus, tobacco, and pine trees. The plants develop damping off, a disease state.^[1]

Photographs enlarged from portions of a motion photomicrograph, showing the method of cell wall penetration by Pythium hyphae. A. — Shows hypha growing toward the potato cell wall. B. — Shows hypha attached to wall and about to penetrate. C. — The tip has just broken through the wall. D. — The penetration is complete. Note the black line at the point where the hypha penetrates the wall. This may be due to a rolling up of the potato cell wall about the hypha or to a difference in refraction caused by compression of the wall.
