SECTION AMYLOHYGROCYBE 247 



smooth. Context gray, rubescent where bruised, drying black; odor 

 subfarinaceous, taste none. 



Lamellae sinuate-adnate, uncinate-decurrent, whitish-cinereous to 

 cinereous-subrufescent, broad, distant, faces venose. 



Stipe 4-5 cm long, 2-2.5 cm thick, cinereous-fuscescent, reddish- 

 spotted where bruised, attenuated below, subfibrillose to pruinose. 



Spores 6-8 X 3-3.5 /x, obovate-elongate to subcylindric, hyaline. 

 Basidia 28-35 x 6-8 fi, clavate. 



Habit, Habitat, and Distribution — On soil, Europe and boreal 

 America (Bresadola 1928). 



Matebial Studied — Denmark: Jensen (Hesler 23966). 



Oesebvations — Although reported from North America by Bresa- 

 dola, we have not seen material of this species from North America. It 

 probably has been confused with H. ovinus, which has larger, non- 

 amyloid spores. 



The description given above is based on Bresadola (1928). Our 

 notes on the Danish collection, kindly communicated to us by Dr. 

 Morten Lange and Mr. J. P. Jensen, are as follows: Spores 6-7 X 

 3-3.5(4) fx, ellipsoid to phaseoliform, smooth, amyloid. Basidia 42-50 X 

 6-7 fx, 4-spored. Pleurocystidia and cheilocystidia none. Gill trama sub- 

 parallel, hyphae (5)10-16 /a broad. Cuticle a cutis of fuscous, non- 

 gelatinous hyphae. Pileus trama of more or less radial hyphae. 



Apparently the odor varies from faint to strongly farinaceous.
