88 SECTION CAMAROPHYLLOPS1S 



Melzer's reagent. Basidia 37-44 X 4.5-6 /x, 4-spored, sterigmata up to 

 8 /x long. Pleurocystidia and cheilocystidia none. Gill trama intricately 

 interwoven, hyphae 2-4.5 /x broad. Cuticle repent-fibrillose, some hy- 

 phae more or less erect. Clamp connections present on the cuticular 

 hyphae. The pileus cuticle is non-gelatinous in KOH. The lamellae ap- 

 parently vary in color from whitish to pale gray, or they may be whitish 

 with a violaceous tint. 



This species is distinguished from H. albipes in its paler color when 

 dried, its larger stature, its broader, grayish to violaceous lamellae, and 

 its lack of a gelatinous or even a subgelatinous cuticle. The types of 

 these two species do not resemble each other.

Hygrophorus canescens Sm. & Hes. 

 Lloydia 5: 10. 1942 



Camarophyllus canescens (Sm. & Hes.) Singer, Lilloa 22: 148. 1951. 



Pileus 2-4.5 cm broad, obtuse, becoming convex, the margin in- 

 curved and lobed or somewhat irregular, "benzo brown" to "drab 

 gray," fading to pallid sordid gray in age, surface at first canescent from 

 a thin coating of appressed fibrils, glabrescent, dry or moist, not viscid, 

 opaque at all stages. Context grayish, unchanging, thin, fragile; odor 

 and taste mild. 



Lamellae broadly arcuate-adnate to subdecurrent, "Quaker drab," 

 becoming "light mouse gray" (deep bluish gray), fading when dried 

 and then concolorous with the pileus, subdistant to distant, narrow, 

 broadest near point of attachment, narrowed outward, edges even. 



Stipe 4-6 cm long X 6-8 mm thick, white at the base, elsewhere 

 near "pallid purplish gray," enlarged above, glabrous and somewhat 

 longitudinally streaked, hollow. 



Spores 4-5.5(6) X 4-4.5 /x, at times globose, more often subovoid, 

 smooth, pale yellowish in Melzer's reagent. Basidia 34-51 X 4.5-6 /x, 2- 

 and 4-spored, mostly 4-spored; sterigmata 5-8 fx long. Pleurocystidia 

 and cheilocystidia none. Gill trama compactlv and intricately inter- 

 woven, hyphae 2.5-5 /x broad. Cuticle of interwoven hyphae with nu- 

 merous more or less erect, slender (1-3 /x) hyphae, non-gelatinous, a 

 trichodermium. Pileus trama more or less radial, interwoven. Clamp 

 connections present on the cuticular and gill trama hyphae.
