A. —Sporophores developed in a dense stand of Agropyron smitkii, which protected 
them from rapid drying. In this location the tops were smooth. The fruiting body 
was 12 cm. in diameter. 
B. —Sporophore from the same ring as figure A, but freely exposed and showing the 
rough scaly top. The fruiting body was about 12 cm. in diameter. 
C. —Typical of fruiting bodies exposed on dry hot days. Fruiting bodies 10 cm. in 
diameter. The figures of Plate 11 show variation in pileus. Akron, Colo., June 15,
