Abstract/Contents: | The slime mold Didymium squamulosum (Alb. & Schw.) Fries was found at a high level (two to six sporangia per gram of cleaned seed) among seed harvested from a field of creeping bentgrass (Agrostis stolonifera L.) near Salem, Oregon, in 1992. This is the first report of D. squamulosum associated with seed. Sporangia, with detached stalks, were similar in size (0.4-0.7 mm) and shape to small-seeded bedstraw (Galium sp.), a weed in bentgrass, and may be mistaken for those of the weed without microscopic examination. The field was maintained under recommended management practices during the previous 2 yr, and factors contributing to the occurrence of D. squamulosum at such high levels have not been identified. It is likely the mold was present on the foliage and collected with the seed during harvest. Although slime molds are not considered important pathogens of turfgrass, the introduction of D. squamulosum with seed may contribute to its dissemination and occurrence on foliage in bentgrass plantings. |
