 ODOR and TASTE agreeable. 



Solitary on the ground especially along city pavements, or 

 eaespitose on lawns or grassy places. Throughoul the state. Ann 

 Arbor, Detroit, Holland. Houghton, etc. May-October. Not infre- 

 quent. 



A well-marked species, whose margined, hand like annulus. nar- 

 row gills, solid stem and squatty hahit characterize it sufficiently. 

 The young skills are white for a much Longer time than in /'. 



campestris. The pileus may become yellowish-tinged bu1 the flesh 

 is not changed by bruising excepl that it becomes slightly rufescent 



in the stem. Peck says the annulus is rather thick at times; in our 



specimens it was thin and almost membranous. Sometimes it occurs 



on lawns in dense, eaespitose clusters of ."til to ion individuals; 



such a growth was observed in Ann Arbor by myself, and the same 

 condition has been reported to me by I>r. L. L. Hubbard at Houghton. 

 it apparently prefers city conditions, as it is almost exclusively 



round there, it is edible and much prized by those acquainted with 

 it.
