stropharia. 703. A. stercorarius Fr. Pileus 2.5 cent, (i in.) broad, yellow, 

 fleshy, but thin at the margin, hemispherical then expanded, 

 obtuse, orbicular, pelliculoso-viscous, naked, smooth, even, or at 

 length slightly striate only at the margin. Stem 7.5 cent. (3 in.) 

 and more long, 4-6 mm. (2-3 lin.) thick, stuffed with a separate 

 fibrous pith, equal, clotJied to the ring (which is scarcely 2.5 cent., 

 i in., distant from the pileus, viscous, narrow, but somewhat 

 spreading) with tlie flocculose veil which is at tJie same time viscous 

 (so that it appears as if smooth), yellow. Gills adnate, very 

 broad behind, 4 mm. (2 lin.) broad, somewhat crowded, umber- 

 fuscous or olivaceous-fuscous, of one colour, quite entire. 



Stem silky-viscous when moist, when dry becoming even, shining and 

 yellowish - white, and without a manifest veil. The gills are truncate and 

 somewhat decurrent. It is often confounded with A. semiglobatus; Sow. t. 

 249 seems to have this in view.
