 first grayish, at length briglil flesh color. Spores angular. 



The imperfect and abortive forms present all stages of imperfection 

 lo a complete obliteration of all semblaiJce of stipe and pileus when the 

 fungus consists of a rounded more or less lobed mass. 



In woods about old logs and stumps. Pileus .3 in. or more in breadth, 

 stipe 2-.1 in. long. The abortive forms sometimes cohere together in

Sjwrcs rosy. Pileus thin, umbilicate, or with the disk darker ; the 

 margin at first incurved. Stipe cartilaginous, tubular, polished, 

 winning. Lamellae at first attached or adnate, but easily seceding. 



90. A. AsruELLUS, Fr. — Pileus somewhat membranaceous, convex 

 then explanate, sometimes glabrous, sometimes fibrillose, striate, the 

 umbilicus vilhtus and at length scaly, fuliginous, then livid gra}-. Stipe 

 hollow, slender, even, glabrous. Lamella' adnate, seceding, equally at-

In pastures and grassy places. Pileus 1-lA in. broad. Stipe 1-2 in.
