SUBSECTION CAMAROPHYLLl 361 



pinkish, glabrous, viscid, margin even. Context whitish, medium thin; 

 odor and taste not distinctive. 



Lamellae decurrent, pale buff, rather close to subdistant, medium 

 broad, edges even. 



Stipe 3-5 cm long, 4-6 mm thick, pallid to pale buff, white-fibrillose 

 above the veil-remnants, dry, equal. Veil white-fibrillose, copious. 



Spores 5.5-6(7-8) X 3.5-4 /x, ellipsoid to subellipsoid, smooth, yel- 

 low in Melzer's reagent. Basidia 42-54 X 6-8 /x, 2- and 4-spored. Pleuro- 

 cystidia and cheilocystidia none. Gill trama divergent, hyphae 4-9 /x 

 broad. Cuticle a zone, 180-300 /x broad, composed of colorless, loosely 

 interwoven, gelatinous hyphae. Clamp connections present on the cu- 

 ticular and gill trama hyphae. Cuticular hyphae of the stipe are non- 

 gelatinous and have clamps. 



Habit, Habitat, and Distribution — On soil, under conifers, 

 Idaho, August. 



Material Studied — ddaho: Smith 59968 (type, from northeast of 

 Burgdorf, Aug. 13, 1958). 



Observations — This species is clearly related to H. purpurascens, 

 but the pileus lacks the red fibrils, and the lamellae are not reddish- 

 spotted. Consequently, we place it here.

Illustration: 

 Fig. 114. 



Pileus 2-3 cm broad, convex, margin incurved, expanding to plane 

 or the margin elevated slightly and the disc depressed, "Isabella color" 

 with a "warm buff" margin, disc becoming tinged with cinnamon and 

 then more or less "saval brown," glutinous and appearing fibrillose- 

 streaked beneath the gluten. Context odor and taste not distinctive. 



Lamellae decurrent, "ivory yellow" becoming "warm buff," narrow, 

 distant. 



Stipe 4-6 cm long, 3-6 mm thick at apex, concolorous with gills, 

 equal or narrowed downward, dry, with a median fibrillose zone from 

 the partial veil. 



Spores 8-10 X 4-5 /x, nearly elliptic in face view, smooth, hvaline in 

 KOH, yellowish in Melzer's reagent. Basidia 38-50 X 8-9 ti, 4-spored. 

 Pleurocystidia and cheilocystidia none seen. Gill trama divergent. Cuti- 

 cle a well-defined zone 200-300 p thick, of fuscous, gelatinous hyphae, 

 2-3.5 fx broad, more or less erect, loosely tangled (no palisade), an 

 ixotrichodermium. Hypodermium indistinct or none. Pileus trama of
