SUBSECTION CAMAROPHYLLI S8S 



Material Studied— ida ho: Smith 54516, 54581, 54605, 54781, 

 54945, 54997, 55136, 55187. Oregon: Smith 28300, 28387 (type, from 

 Paradise Park Trail, Mt. Hood, Oet. 28, 1957). 



Observations — In the field this fungus was mistaken for slender 

 specimens of H. agathosmus, but the large spores on 4-spored basidia 

 make such a disposition untenable. Hygrophorus lucandi Gill, is usu- 

 ally described as having the field characters of //. odontitis, and one is 

 tempted so to designate our collections. However, we have no reliable 

 information on the spore size of Gillet's species and deem it best not to 

 risk confusing a distinct American species with a European species 

 which European authors have regarded as a synonym of H. agathos- 

 mus. Actually, H. odoratus appears to be related to H. pacificus Sm. & 

 Hes., but differs in the gray pileus and faint tinge of yellow which is 

 evident in age. In spore size, odor, and dry stipes they are similar. H. 

 hyacinthinus Quel, appears to be closely related by virtue of its pale 

 gray to white cap, and with spores 9-11.5 X 5-6 /x. The apex of its stipe 

 is said to be silky. In a collection of Smith (54581) identified as H. 

 odorus because of its pale coloration, the spores measure 9-11.5 X 5.6 /x.
