extreme half-line of the pileus sharply incurved, and with a 

 raised zone near the margin. (Fries.) 



Cortinarius (Hygr.) illuminus. Fr. 



Pileus 1^-3 in. across, rather fleshy, convexo-plane, 

 gibbous, glabrous, pale brick-red or reddish-tan, margin 

 thin ; gills adnate, rather distant, about 2 lines broad, pallid 

 then cinnamon ; stem 2-4 in. long, 3-5 lines thick at the 

 base, attenuated upwards, silky fibrous, pallid becoming 

 ferruginous; imperfectly hollow; veil white; spores fer- 

 ruginous, elliptical, 11-12 x 6-7 /JL.

Separated by slight features, hence difficult to distinguish 

 from Cortinarius subferrugineus, C. armeniacus, and C. balaus- 

 tinus. Stem soft, almost hollow, 3-4 in. long, 3-5 lines 

 thick, attenuated upwards, silky-fibrillose, becoming fer- 

 ruginous, but pallid, inside and base white. Veil evident, 

 fibrillose. Pileus rather fleshy, obtusely umbonate, 23 in. 

 broad, even, under a lens slightly innato-fibrillose, virgate, 

 for the rest glabrous, reddish-tan when moist, paler when 

 dry. Gills adnate, scarcely crowded, at first pallid (reddish- 

 tan), 2 lines, when adult 5 lines broad, cinnamon, base often 

 venose. A form occurs in beech woods with a yellowish- 

 white, stutfed stem, and the pileus more distinctly tawny- 

 cinnamon ; another form in pine woods has the stem elongated 

 and twisted almost as in C. tortuosus. (Fries.) 



Coitinarius (Hygr.) tortuosus. Fr. 



Pileus 1^-2 in. across, rather fleshy, convex, rather gibbous, 

 even, shining, ferruginous-bay or brick-red ; gills adnate, 

 crowded, margin quite entire, tawny, becoming blood-red 

 when bruised; stem 34 in. long, 3-4 lines thick, equal, 

 rigid, rather twisted, silvery, imperfectly hollow ; spores 

 elliptic-oblong, ferruginous, 15-16 x 8 /*.

In damp pine and other woods. 



Stem sometimes short, usually elongated and much twisted, 

 rooting, apex at first tinged with violet. Easily distinguished
