A zonate leaf spot of Pennisetum clandestinum turf, found during the 1979 dry season in Brazil, was incited by Drechslera bicolor. Spots are dark purple and gray and reach a maximum size of 3 × 1 mm. A small fleck leaf spot of P. ciliare grown under pasture conditions in 1979 was caused by D. maydis. Flecks are reddish brown at first and later become so numerous that they coalesce, resulting in a leaf tip blight. Both pathogenic combinations appear to be new.
