Cap sJ^ to 5 inches broad; stem about 2 inches long. 



This fungus is noticeable on account of the color and areolate character of the 

 cap. In Virginia, Maryland, and the District of Columbia it occurs commonly either 

 solitary or in small patches, but not in very great abundance, from July to September, 

 but it has been found from June through the entire summer and into October. The 

 species is edible and of good flavor. 



CORTINAKIUS 



The genus Cortinarius is easily recognized when young among the ocher-spored 

 agarics by the powdery gills and by the cobwebby veil, which is separable from the 

 cuticle of the cap. In mature plants the remains of the veil may often be observed 

 adhering to the margin of the cap and forming a silky zone on the stem. Cortinarius 

 contains many forms which are difficult of specific determination. Many species 

 are edible, some indifferent or unpleasant, and others positively injurious. The 

 colors are generally conspicuous and often very beautiful. Most of the species 

 occur in the autumn. 



Cortinarius cinnamomeus {Edible) 



Cap rather thin, conic campanulate, when expanded almost plane, but sometimes 

 umbonate, yellow to bright cinnamon-colored, with perhaps red stains, smooth, silky 

 from innate, yellowish fibrils, sometimes concentric rows of scales near the margin; 

 flesh yellowish; gills yellow, tawny, or red, adnate, slightly sinuate' and decur- 

 rent by a tooth, crowded, thin, broad; stem equal, stuffed then hollow, yellowish, 

 fibrillose. 



Cap I to 2 J^ inches broad; stem 2 to 4 inches long, 3 to 4 lines thick. 



This is a very common and widely distributed species, particularly abundant in 

 mossy coniferous woods from summer until fall. The color of the gills is an extremely 

 variable character, ranging from brown or cinnamon to blood red. A form possess- 

 ing gills of the latter color is known as Cortinarius cinnamomeus var. semisanguineus. 

 This species and variety are edible and considered extremely good. 



Cortinarius lilacinus {Edible) 



Cap firm, hemispherical, then convex, minutely silky, lilac-colored; gills close, 

 violaceous changing to cinnamon; stem solid, stout, distinctly bulbous, silky fibril- 

 lose, whitish with a lilac tinge. 



Cap 2 to 3 inches broad; stem 2 to 4 inches long. 



This is a comparatively rare but very beautiful mushroom and an excellent edible 

 species. 



Cortinarius sanguineus {Edible) 



Cap convex, then plane, or perhaps slightly umbonate or depressed, blood red, 

 silky or squamulose; flesh paler reddish; gills crowded, entire, adnate, dark blood 

 red; stem stuffed or hollow, sometimes attenuated at the base, dark as the cap and 

 fibrillose, containing a red juice.
