Leptosphaerulina Explained

Leptosphaerulina is a genus of fungi in the class Dothideomycetes.^[1] The relationship of this taxon to other taxa within the class was unknown in 2007 until it was placed within the Didymellaceae family in the Pleosporales order.^[2] The genus was first described by Australian plant pathologist Daniel McAlpine in 1902.^[3]

Situation: A range of cool season grasses.

Turf damage: Uniform yellow or brown lesions may extend down to the leaf sheath. Water-soaked lesions, which quickly fade to a bleached white, may also occur on the leaf blades.

Occurrence: Disease outbreaks can occur during warm, humid weather on fescue, ryegrass or bentgrass. Large turf areas become uniformly blighted or appear patchy with individual leaves dying back from the tip.
