Kauffman : The genus Cortinarius 323 



found ; margin when young with narrow strips, of silky fibrils from 

 the universal veil ; pileus when old covered with innate, whitish, 

 silky fibrils, hygrophanous ; surface punctate^ even when young. 

 Flesh of stem and pileus lavender (Ridg.) when young but soon 

 fading to a sordid white, thick on disk, abruptly thin towards 

 margin, soon cavernous from grubs. Gills very broad, as much 

 as 2 cm., at first lavender^ soon very pale-tan to cinnamon, 

 rather distant, thick, emarginate with a tooth, at first plane 

 then ventricose ; edge slightly serratulate, concolorous. Stem as 

 much as 13 cm. long (usually 8 to 10 cm,), 1-2 cm. thick, 

 usually thickened below and tapering slightly upwards, mostly 

 thicker also at apex, rarely attenuate at base, sometimes curved, 

 always sto7it^ solid, lavender above the woven, sordid white, universal 

 veil, which at first covers the lower part as a sheath, but soon breaks 

 up so as to leave a band-like annulus half-way or lower down on 

 the stem, or remains on the base of the stem as white fibril- 

 lose patches ; soon of same color as pileus, hygrophanous, soon 

 cavernous. The annulus is easily rubbed off, leaving a bare stem. 

 Cortina violaceous-white. Spores 7-9 fx x 5— 6/i, almost smooth ; 

 basidia about 40 /i long. (Figure 4.) 



Troops of 25 plants were found under a clump of hemlock 



trees on the edge of a swamp, north^of Freeville, N. Y., August 



29, 1903, and August 22, 1904, C. H. Kauffman.

 its lengtJi by the cJirome-yellozv to saffron veil, paler above the veil,
