ABSTRACT

The circles or arcs of prompted or suppressed plant growth or of the fruiting bodies of soil-inhabiting fungi which often occur in floors of woodlands, agricultural or grassland in most parts of the world are generally called “fairy rings”. The symptoms of fairy ring are initially approximately 10 of centimeters or less in diameter, and expand in size year after year, reaching up to several meters in diameter in old turf stands. Marasmius oreades is the most common cause of the growth-suppressed type of fairy rings in all types of turfgrass. “Fairy rings” is a phenomenon in which fruiting bodies of higher fungi occur after turfgrass grows and/or dies in the form of rings. Many fungi species, mostly Basidiomycetes, have been recorded associated with fairy rings. Pathology of fairy rings by M. oreades has shown that the organism can infect and colonize the roots of Kentucky bluegrass, creeping red fescue and Colonial bentgrass.
