Summary:

Fairy-rings grow because the fungal spawn radiates outwards then dies off at the centre as it becomes exhausted. The verdure of the grass depends upon the decay of the fungus supplying nitrogenous manure. Rings are formed mainly in upland pastures poor in nitrogenous matter. Gives examples of woodland fungi that form rings.
