729. A. agrarius Fr. — Pileus 2.5 cent, (i in.) rarely 5 cent. (2 

 in.) broad, at first white and without lustre, by no means becoming 

 pale but becoming cinereous in drying, not hygrophanoiis, slightly 

 firm but slightly fleshy, convex, at length flattened, and then often 

 umbonate, even, smooth ; flesh firm, white, but not 2 mm. (i lin.) 

 thick. Stem 4-5 cent. (1^-2 in.) long, 2-4 mm. (1-2 lin.) thick, 

 fistulose, equal, smooth, white. No veil conspicuous. Gills

 white gills.
