PLATE 19 
A garicus tabularis: 
A. —Part of a large ring, showing 42 mushrooms. The area just inside the fruiting 
zone is marked by dead or dying short grass. Inside this dead zone is a stimulated 
area chiefly characterized by Fesiuca octoflora. Akron, Colo., June 15, 1915. 
B. —A large ring, showing 75 fresh mushrooms. There are also 47 dry mushrooms. 
Outside the ring the vegetation is typical short grass. A narrow stimulated area, 
marked largely by Fesiuca octoflora extends several inches in advance of the fruiting 
zone. Just inside the fruiting zone the short grass is dead. Inside this dead zone 
the vegetation consists largely of annuals and Malvastrum coccineum , with short grass 
slowly becoming reestablished at a distance of about 4 meters inside the fruiting zone.
