Typhula variabilis

Typhula variabilis is a species of fungus in the family Typhulaceae. It is commonly known as the variable snow mold. This fungus is known to cause damage to turfgrass in cool and wet conditions.

Description

Typhula variabilis typically forms small, white mycelium patches on the surface of grass blades. These patches can vary in size and shape, hence the name "variable snow mold." Underneath the mycelium, the grass may appear water-soaked and discolored.

Life Cycle

The life cycle of Typhula variabilis begins with the germination of spores on the grass surface. The fungus then grows and spreads through the grass blades, feeding on the plant tissues. In favorable conditions, it produces fruiting bodies that release spores to continue the cycle.

Prevention and Control

To prevent and control Typhula variabilis infestations, it is important to maintain proper turfgrass health. This includes regular mowing, adequate fertilization, and proper drainage to reduce moisture levels. Fungicides can also be used to manage severe outbreaks.

Impact

Variable snow mold caused by Typhula variabilis can result in significant damage to turfgrass, leading to thinning and discoloration of the lawn. This can affect the aesthetic appeal of the lawn and may require reseeding or renovation to restore the grass to its healthy state.
