SUBSECTION CAMAROPHYLLI 323 



Material Studied — Oregon: Smith 22027 (type, from East Fork, 

 Salmon River, Mt. Hood, Oct. 20, 1944). 



Observations — This species is related to H. discoideus which, 

 however, has a gelatinous veil. Excellent material was studied, and 

 the lack of a glutinous veil in H. subpungens was definitely established. 

 The colors of H. subpungens are paler and the spores smaller than in 

 H. discoideus. It is only remotely related to H. russocoriaceus which, 

 according to material from Bas, in the Netherlands, is a Camaroplujl- 

 lopsis.
