PILEUS 5-12 cm. broad, convex, obtuse, subexpanded, dry, dark 

 violet, covered with villose, minute suberect tufts or scales, at length 

 metallic-shining. FLESH rather thick, varying gray to dark 

 violet, not becoming purple when bruised. GILLS adnate, becom- 

 ing sinuate or emarginate, thick, broad, subdistant, very dark 

 violet, becoming ashy-cinnamon. STEM 7-12 cm. long, long and 

 stout, clavate or clavate-bulbous, 10-15 mm. thick above, dark violet, 

 fibrillose, spongy in the rounded bulb, violaceous within, bulb large. 

 SPORES large, rough, broadly elliptical, 12-16x7-9 micr. (often 

 16-18 micr. long, then smoother and more elongated). ODOR and 

 TASTE mild. 



Solitary or scattered. Among mosses, fallen leaves and debris 

 of conifer woods. Found only once in Michigan ; Isle Royale, Lake 

 Superior. Frequent at North Elba, Adirondack Mountains, New 

 York. August-October. 



A striking species, not to be confused with dry specimens of the 

 viscid-capped species, such as C. purpurasceris, G. spltaerosperma, 

 etc. The stem is usually long as compared with these, and the cap 

 correspondingly smaller. The peculiar metallic luster of the dry 

 mature pileus was observed in both our native collection and in 

 Sweden. Both also had the characteristic fine-hairy-scaly surface 

 not easily shown in figures but approached by Fries. No photo- 

 graphs exist which show this character well. The abnormally large 

 spores were present in both our own and the Swedish plants. The 

 whole plant is at first dark deep violet with an indigo tinge. Al-
