fading, toughish. Odor strongly farinaceous, taste similar. Spores 

 suboblong, smooth, hyaline, 6-6.5(7) x 3-3.5 ji; cystidia none; 

 basidia 4-spored 45-50 x 4-5 fi ; sterile cells on edge of gills in- 

 conspicuous; gill-trama with parallel-diverging hyphae, those in 

 axis parallel. 



On deep moss and on needle beds in hemlock, cedar and fir 

 forest. Gregarious to subcespitose. Mt. Hood, Oregon. Octo- 

 ber 1 to 15. Collected by L. E. Wehmeyer. 



This species has much the appearance and habit of Clitocybe. 

 It is, however, a true Hygrophorus, as shown by its viscid veil 

 and by its gill structure. It belongs to the subgenus Limacium. 

 Its near relatives all have distant gills. When artificially dried 

 after collecting, those growing in wet weather dry dark while 

 those already wind-dried retain their colors. 

 Hypholoma fasciculare Fr. 



Hypholoma olivaespora Ellis. — See H. vinosum Kauff. (12, p. 

 261), which is a synonym. 



Hypholoma canoceps, sp. nov. — Pileus 1-2 cm. broad, about 

 1 cm. high, fragile, conical-campanulate to broadly conical, 

 hygrophanous, "cinnamon-drab" (R.) when moist, but this 

 ground-color almost hidden except on umbo by an appressed 

 radially disposed, white-villose innate silkiness, slowly fading, at 

 length subglabrescent, margin at first straight, appressed silky, 

 not striate; flesh thin, concolor. Gills adnate, rounded behind, 

 seceding, narrow, 2 mm., crowded, "cinnamon-drab," white- 

 flocculose on edge. Stem 4-6 cm. long, 2.5-3 mm. thick, equal, 

 white, fragile, straight or curved at base, hollow, even, at first 

 covered by a rather persistent white-silky floccosity, at length 

 glabrescent, whitish within, rather cartilaginous. Odor and taste 

 none. Spores elliptic-oblong, subobtuse, smooth, purplish- 

 brown, 8-9.5 X 3.5-4.5 //; cystidia on sides of gills are lack- 

 ing; sterile cells on edge short cystidia-like, ventricose-subglobose 

 above pedicel, with abruptly narrowed, cjdindric neck, thin- 

 walled, hyaline, 40-50 X 8-12 ju, neck 4 {j. diameter. 



On very rotten pieces of wood mixed with black alluvial 

 moist soil in conifer forest. Mt. Hood, Oregon. October 14.
