| Abstract/Contents: | "In 2010, previously unreported disease symptoms were observed on golf course putting greens located in the United Kingdom and Pennsylvania. Since this initial discovery, similar symptoms have subsequently been reported in California, Michigan, South Dakota, Australia, and New Zealand on golf putting greens and fairways. Symptoms of this disease include circular patches of degraded organic matter (e.g. thatch) ranging from approximately 8 to 46 cm in diameter. Thatch degradation results in an indentation of the turf surface and disrupts playability. Commonly found in association with the thatch degradation is a basidiomycete not previously reported within stands of any turfgrass. Fungal signs included profuse, clamp connected mycelia within the upper 2.5 cm of the soil/thatch profile and peridium within the thatch and canopy of golf course putting greens. The fungus was isolated on oatmeal agar and DNA was extracted and the internal transcribed spacer region (ITS) was amplified with the primer set ITS4/ITS5. A 703 to 707-bp sequence was obtained and found to be 99% similar to an accession of Sphaerobolus stellatus in the NCBI database. S. stellatus is a basidiomycete commonly found within wood mulch. Based on these results, S. stellatus may be responsible for rapid lignocellulose degradation resulting in thatch collapse on turfgrass species. Ongoing studies are being conducted to better understand the biology of this fungus and to confirm S. stellatus as the cause of thatch collapse symptoms." |
