Fairy Ring

A disease of turf, but often classed as a disorder due to the indirect causes involved, consisting of three main types:
• Type 1, which is the most serious, producing a dead zone within a ring that is surrounded by grass growth either side of the dead zone. This type is mostly caused by the fungus Marasmius oreades. Moss and weeds typically start to colonise the dead grass area of a Type 1 attack.
• Type 2 and Type 3 primarily have a cosmetic effect on the turf: Type 2 produces a green band like ring of flushed growth, sometimes with mushrooms, toadstools or puffballs being present.
