PLATE 18 
A garicus tabularis: 
A ring which produced only a few mushrooms in 1915. It is marked by the stimu¬ 
lated growth of Festuca octoflora. In this stimulated area three distinct maxima can 
be distinguished which form concentric rings. The first maximum occurs just inside 
the fruiting zone, the second about 2 feet inside, and the third about 4 feet inside the 
fruiting zone.
