What is one distinguishing feature of Fairy Ring on turfgrass?

Fairy ring is a unique fungal phenomenon commonly seen in turfgrass, characterized by rings or arcs of lush green grass. This occurs due to the mycelium of certain fungi breaking down organic matter in the soil and facilitating an enhanced level of nutrient availability in that area. As a result, you'll observe the contrasting green growth within the ring compared to the surrounding grass. This enhanced growth often appears more vibrant due to increased moisture and nutrient circulation, creating a visually distinct ring of green grass.

The presence of large patches of yellowing grass, dry, brittle leaves, or the absence of any fungal growth does not accurately represent the characteristics of fairy ring. In fact, yellowing generally indicates stress, which is not associated with fairy ring where there is a beneficial effect on grass growth around the fungus. Similarly, dry and brittle leaves would suggest poor health or drought conditions, rather than the thriving conditions created by fairy ring fungi. Finally, the presence of fungal growth is a critical component in identifying fairy rings, making its absence inconsistent with the phenomenon.
