418. A. sinuatus Fr. Pileus 15 cent. (6 in.) broad, becoming 

 yellow-white, very fleshy, convex: then expanded, at first gibbous, 

 at length depressed, repand and sinuate at the margin. Stem 

 7.5-15 cent. (3-6 in.) long, 2.5 cent, (i in.) thick, solid, firm, stout, 

 equal, compact, at first fibrillose, then smooth, naked, shining 

 white. Grills emarginate, slightly adnexed, 12-18 mm. (}4-tf 

 in.) broad, crowded, distinct, pale yellowish-rufescent. 



Gregarious, compact, handsome. Odour strong, pleasant, almost like that 

 of burnt sugar, not of new meal. The pileus becomes broken into squamules 

 when dry. There is a variety with a shorter stem.
