Kauffman : The genus Cortinarius 



Cortinarius Atkinsonianus sp. noy. 



Pileus 8 cm. broad, expanded, wax-yellozv or gaUstonc-yellozv to 

 day-colored and tazviiy (Ridg.), colors very striking and sometimes 

 several present at once, viscid, smooth, even, somewhat shining 

 when dry. Flesh thick, except at margin, bluish-white like the 

 stem, or paler, scarcely or not at all changing when bruised. Gills 

 comparatively narrow, 6-8 mm., w^dth uniform except near outer 

 end, adnate becoming slightly sinuate, purplish to yellow, then cin- 

 namon. St^m violacco7iS-blnc^ 8 cm. long, 12-15 mm. thick, equal 

 or slightly tapering upward, hidbous by a rather thick, marginate 

 bulb 3 cm. thick, hung with the fibrillose threads of the universal 

 veil, which is a beautiful pale-yellow and clothes the bulb even at 

 maturity; violaceous-blue within, solid. Spores 13-1 5^ax 7 — 8.5 /i, 

 very tubercular. (Figure 6.) 



Figure 7, Cortinarim deceptivus Kaufl. Slightly reduced. Young stages. 



The nature of the universal veil indicates its position in the 

 subgenus Tvlainonia, but the viscid cuticle bars it. It needs further 

 study. Only a single, rather mature specimen was found, among 

 hemlocks and poplars, at the base of a sassafras sapling, Enfield 

 Gorge, near Ithaca, N. Y.. September 14, 1903, C. H. Kauffman.
