Spores 7-9 x 4.5-5.5 /*, ellipsoid or nearh so, smooth, yellowish in 

 Melzer's reagent. Basidia 48-60 x 8-10/1, 1 spored. Pleurocystidia and 

 cheilocystidia not soon, (nil trama intricately interwoven, hyphae 

 2.5-5 /a broad, hyaline in K( )l I. Surface hyphae repent, non-gelatinous, 

 forming an undifferentiated cutis. Hypodermium not differentiated. 

 Pilous trama loosely but intrioatoK interwoven, the hyphae chief!) 

 disposed radially, ("lamp connections abundant. 



Habit, Habitat, and Distribution — Caespitose-gregarious in a 

 swampy area under cedar and alder, Oregon. October. 



Material Studied — Oregon: Smith 27411 (type, from East Fork, 

 Salmon River, Mt. Hood, Oct. 8, 1947). 27448. 



Observations — The interwoven gill trama clearly places this 

 speeies in Camarophyllopsis where it is distinguished by the pinkish 

 cinnamon color and sweetish sickening odor. It has much the stature 

 of H. pratensis but differs in color and in having a peculiar odor. Be- 

 cause of the odor one might regard this species as close to //. rus- 

 socoriaceus, a European species, but it cannot be considered identical 

 without making major alternations in the concept of the latter.
