These species of hosts can include creeping bentgrass, annual ryegrass, and perennial ryegrass. Some of its more common hosts include fine fescue, tall fescue, and Kentucky bluegrass. [7] Symptoms of the pathogen often manifest in all species the same way; as circular patches 6 inches to a foot in diameter of dead or damaged turfgrass. [6]

[2] Brown patch is also found in Kentucky bluegrass (Poa pratensis) and Fine fescue (Festuca sp.) but this is rare or does minimal [clarification needed] damage. [3]
