Beniowskia sphaeroidea Blight on Knotroot Bristlegrass in Georgia. E. A. Brown, Extension Plant Pathology Department, University of Georgia, Athens 30602. R. T. Hanlin, Department of Plant Pathology, University of Georgia, Athens 30602. Plant Dis. 66:1197-1198. Accepted for publication 1 August 1982. Copyright 1982 American Phytopathological Society. DOI: 10.1094/PD-66-1197.

Small, white, cushion-shaped sporodochia and globose conidia borne on short denticles of a fungus found parasitizing Setaria geniculata in pastures in Greene County, GA, were identified as Beniowskia sphaeroidea. This is the first report of this fungus in Georgia, and apparently only the second in the United States. The potential of this fungus as a threat to cattle and to pasture grasses is discussed.
