Hymenophore waxy, spores rarely ornamented, white in deposit; 

 lamellae typically thick but with sharp edges, usually distant to sub- 

 distant and characteristically with a clean appearance; stipe confluent 

 with pileus and nearly always centrally attached; basidia typically 

 long and narrow as in species of Cantharellus. 



Type species: Hygrophorus eburneus (Bull, ex Fr. ) Fr. 



Discussion: The waxy nature of the hymenophore is a difficult 

 character to ascertain because it is to a large degree subjective. Be- 

 cause of this, certain aids in the accurate identification of the genus 

 are pointed out at this time. If the gill edges are blunt, try Cantharellus 

 first. In Cantharellus the hymenophore is somewhat waxy and clean in 

 appearance. If a collection is at hand which has keyed out to Clitocybe 

 and the basidia are long and narrow, it may be an Hygrophorus. My- 

 cena and the smaller species of section Hygrocybe do intergrade, and 

 some experience will be necessary with both genera before accurate 

 assignments can be made. Fortunately, the number of such species is 

 small and the fungi themselves are not very frequently collected.
