Obsebvations — Although in the western United States it has been 

 found in dense conifer forests, this species is particularly abundant in 

 pastures around scattered spruce trees. The large specimens collected 

 in southern Oregon with caps 11 cm broad, and stipes 16 cm long and 

 2.5 cm thick were most unusual, but are nothing more than growth 

 forms, and are not taxonomically significant. One must be continually 

 on guard when collecting in this area not to allow oversized specimens 

 to influence his concept of any species. The odor is variously described 

 as of celery, anise, or bitter almonds. In some of our collections the 

 odor was weak. In Europe the stipe is described as having pallid, yel- 

 lowish, or fuscescent squamules. In California, a pale form (Smith 

 56477) was found. In it, the pileus was pallid, the disc cinereous, and 

 the surface faintly zonate. A slender form (Smith 52032), also from 

 California, has been collected. 



Following the observations of Dennis (1948), we have listed H. 

 cerasinus as a synonym of H. agathosmus. He studied the type of H. 

 cerasinus and states that there is no adequate grounds for separating 

 the two species. Niiesch (1922) also lists H. cerasinus as a synonym.
