402 . THE AGARICACEAE OF MICHIGAN 



The species is quite distinct from the preceding ones inasmuch as 

 every pari is at first cinnabar-red. This color is dissolved out by 

 a weak solution of caustic potash ; and this is also true of G. semisan- 

 guineus and even of some of the preceding species in which the red 

 color is otherwise obscured. The nearest approach to it is G. San- 

 guineus Ft., which I collected near Stockholm and in the Adiron- 

 dack Mountains. 



409b. Cortinarius sanguineus Fr. 



Syst. Myc., 1821.

(iillet, Champignons de France, No. 246. 



PILEUS 2-4 cm. broad, obtuse, or umbonate, campanulate, dry, 

 innately silky or minutely scaly, opaque, dark blood-red. FLESH 

 blood-red, thin on margin. GILLS adnate, rather broad, close, dark 

 blood-red. STEM 5-10 cm. long, 3-7 mm. thick, elongated in moss, 

 equal or tapering, stuffed then hollow, relatively slender, blood-red, 

 darker where bruised. CORTINA fibrillose, tinged red. SPORES 

 narrow-elliptical, 7-8 x 4-5 micr., tinged red, roughish. ODOR mild ; 

 TASTE slightly like radish. 



Gregarious in deep moss or sphagnum in conifer woods. 



Isle Koyale, Sault Ste. Marie, etc., mostly in the northern part 

 of the State. Infrequent. 



Distinguished from G. cinnabarinus by its habitat, its longer stem 

 and more blood-red color. European authors do not emphasize the 

 mossy habitat, but with us this seems to be the usual place of 

 growth. 



The color of every part of this species is dark blood-red, the pileus 

 is silky-scaly and not as broad as that of G. cinnabarinus, the stem 

 is more slender and usually longer; the spores are similar. It 

 grows on thick moss or sphagnum under conifers. Ricken gives 

 measurements which are too large for the Swedish plant. Peck's 

 specimens, reported in the 23d Report, are doubtless G. cinna- 

 bar] mix.
