wet, shining when dry, tawny. The gills are adnate with a peculiar 

 bluish gray tinge when young, and clay color to cinnamon when old. 

 The spores are nearly elliptical, and 12-15 x 6-7 //. The stem is 

 cylindrical, even, and with patches of the cracked gluten when 

 dry. 



Cortinarius (Dermocybe) cinnamomeus (L.) Fr. Edible. The cinna- 

 mon cortinarius is so called 

 because of the cinnamon color 

 ^ of the entire plant, especially 

 o of the cap and stem. It 

 g grows in the woods during 

 G summer and autumn. It is a 

 . . very pretty plant, and varies 



P^ from 5-8 cm. high, the cap 

 from 2-10 cm. broad, and the 

 S^jS stem 4-6 mm. in thickness. 

 c^ The pileus is conic, or con- 



I o vex, and nearly expanded, 

 I sometimes nearly plane, and 

 a'^ again with a prominent blunt

 I 8 Fig. 155, giving the appear- 

 i V. ance of a "hip-roof." The 

 g surface is smooth, silky, with 

 ^S innate fibrils. Sometimes 

 c there are cinnabar stains on 

 S parts of the pileus, and often 

 ^ there are concentric rows of 

 I. scales near the margin. The 

 ^ flesh is light yellowish and 

 g with stains of cinnabar. The 

 o gills are adnate, slightly sinu- 

 ^ ate,anddecurrentby atooth, 

 easily separating from the 

 stem, rather crowded, slightly ventricose. The color of the gills 

 varies greatly ; sometimes they are the same color as the pileus, 

 sometimes reddish brown, sometimes blood red color, etc. This 

 latter form is a very pretty plant, and is var. semi-sanguineus Fr.
