CLASSIFICATION' OF AGARICS 38] 



though oearly always mentioned in 1 1 * « - "lists" of various American 



writers, its local or northern distribution leads me to suspect that 

 other species have been mistaken for it. it Beems to be more fre- 

 quent in the east. 



376. Cortinarius lilacinus Pk. (Edible) 



N. V. State Mus. Rep. 26, L874. 

 Illustration: Plate LXXXI1 of this Report. 



PILEUS 5-9 cm. broad, firm, hemispherical, then convex, minute- 

 ly silky or glabrous, lilac-colored, margin at firsl incurved. FLESH 

 very thick on disk, compact and firm, tinged with lilac. GILLS 

 adnexed, rounded behind, rather broad, thick, close to subdistant, 

 sometimes transversely rivulose, lilac at first, then cinnamon, edge 

 cniiic. STEM stout, 6 I- cm. long, with <i very large clavate hull), 

 15-20 mm. thick above, bulb 24 cm. thick, solid, compact, bulb 

 spongy, tibrillose, lilaceous. SPOKES broadly elliptical, rather ob- 

 tuse, scarcely rough, 8-10x4.5-6.5 micr. 



Gregarious. In low, moist swampy places in mixed or frondose 

 woods. Detroit, Marquette. August-September. Infrequent. 



The lilac color persists in the dried specimens. The bulb is much 

 broader in the young plant than the unexpanded pileus. It is 

 quite distinct from C. alboviolaceus in habit and stature, as well 

 as color. The color of the pileus is like that of the European C. tra- 

 ganus Fr., and so is the general shape of the plant, but thai species 

 is quite distinct by a strong odor ami by its ochre yellow gills at the 

 first More slender plants have been found which apparently be- 

 long here and these are not easily distinguished from the related 

 species such as c. argentatus, C. ooliquus, etc., except by the color.
