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

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

 The spores are nearly elliptical, and 12-15 \ 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 

 of the cap and stem. It 

 grows in the woods during 

 summer and autumn, it is a 

 very pretty plant, and varies 

 from 5-8 cm. high, the cap 

 from 2-10 cm. broad, and the 

 stem 4-6 mm. in thickness. 

 The pileus is conic, or con- 

 vex, and nearly expanded, 

 sometimes nearly plane, and 

 again with a prominent blunt 

 or conic umbo. Sometimes 

 the pileus is abruptly bent 

 downward near the margin 

 as shown in the plants in 

 Fig. 151, giving the appear- 

 ance of a "hip-roof." The 

 surface is smooth, silky, with 

 innate fibrils. Sometimes 

 there are cinnabar stains on 

 parts of the pileus, and often 

 there are concentric rows of 

 scales near the margin. The 

 flesh is light yellowish and 

 with stains of cinnabar. The 

 gills are adnate, slightly sinu- 

 '^" ^ ate, and decurrent by a tooth, 



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-sangnineus Fr. 

 Figure 151 is from plants (No. 2883 C. U. herbarium) collected
