Cortinarius ferrugineo-griseus Pk. Rep., 1909: 46. Pileus con- 

 vex or nearly plane, sometimes with the thin margin upcurved and then 

 appearing centrally depressed, hygrophanous, brownish ferruginous 

 when moist, gray or whitish gray 

 when the moisture has escaped. 

 Flesh whitish. Lamellae 4-6 lines 

 broad, moderately close, adnexed, 

 appearing free in the dried plant, 

 pale cinnamon or clay color when 

 young, brownish cinnamon when 

 mature. Stem equal, abruptlybulb- 

 ous at the base, solid or stuffed, 

 silky fibrillose, sometimes colored 

 like but paler than the pileus, some- 

 times shining, variable in color, 

 whitish below and violet tinted 

 above or entirely violaceous, viola- 

 ceous within. Spores ellipsoid 

 and commonly uninucleate, 10-12 

 x 7-8/t. 



Pileus 3.5-iocm. broad. Stem 

 3. 5-8. 5cm. long, 6-2omm. thick. 



Under pine trees near Natick 

 swamp, Massachusetts. 



The growing plant is often covered with pine needles. It belongs to 

 subgenus Hydrocybe and is closely allied to Cortinarius saturninus Fr., 

 from which it may be separated by its pileus fading to grayish white, 

 and by its solid stem often abruptly bulbous. It also differs in its habit 

 and in its larger spores. Peck. 



As to the edibility of this species, the remarks under C. submargin- 

 alis will doubtless apply to this as well. 



Cortinarius submarginalis Pk. Rep., 1901: 950. Pileus fleshy, 

 firm, convex, becoming nearly plane or concave by the elevation of the 

 margin, viscid when moist, yellowish brown, generally a little paler on 

 the rather definite and commonly fibrillose margin. Flesh whitish. 

 Lamellae thin, close, adnate, creamy yellow when young, soon cinna- 

 mon. Stem rather long, equal or slightly thickened at the base, solid,
