Flammula magna Pk. 



Pileus fleshy, broadly convex, soft, dry, fibrillose or somewhal 

 virgate, pale yellow or buff, the margin commonly becoming 

 revolute with age; flesh whitish or yellowish. 



Lamellae close, adnate or slightly decurrent, often crisped or 

 wavy toward the stem, ochraceous. 



Stem equal or thickened toward the base, fleshy-fibrous, solid, 

 elastic, fibrillose, colored like the pileus, brighter yellow within. 

 Spores subellipsoid, 10 x 6 /x. 



Cespitose. Pileus 10 to 15 cm. broad; stem 7.."> to 10 cm. 

 long, 16 to 24 mm. thick. 



Woods. Highland Park. Collected and identified by Dr. 



Watson. 



Flammula polychroa Perk. (Plate X, Figs. I, 2.) 



Pileus convex then plane, broadly umbilicate, of many colors, 

 at first purple, viscid, the disk fleshy. 



Lamellae broad, rather distant, adnate, slightly decurrent, at 

 first dirty-white, then brownish-purple, at length yellow-brown. 



Stem firm, somewhat woody, at first furf uraceous ; veil floccose, 

 yellowish-purple. 



Pileus 5 to 7.5 cm. broad, stem 2.5 to 3.5 cm. long; spores 

 6 to 8 x 4 to 5 ix. 



On rotten trunks, Thornton, Glen Ellyn, Lisle. The pileus 

 when moist is shining and of a peculiar greenish-yellow, the yellow 

 tints being more pronounced toward the disk. It is clothed with 

 flocci or scales which have the appearance of ferruginous stains. 

 When dry, the color is yellowish-gray. The annulus is evanescenl , 

 being little more than a border of scales of larger size than those 

 which clothe the lower portion of the stem. The stem is slender 

 in proportion to the size of the plant. 



Flammula lenta Pers. 



Pileus pale-whitish, chsk often clay-color, fleshy, convex then 

 plane, obtuse, even, smooth, but very glutinous in wet weather; 

 flesh concolorous. 



Lamellae adnate, decurrent with a tooth, crowded, 2 to 4 mm. 

 broad, whitish, at length stained with the ferruginous spores. 



Stem somewhat stuffed, tough, equal, often viscid, whitish or 

 becoming light-yellow and villous at the base, clothed with whit 

 floccose reflexed scales. 



Over buried roots of an oak stump. Winfield. October, 

 1904. Gregarious, flesh white, that of the stem at length brownish 

 toward the base. The lower third of the stem often becomes 

 distinctly hollow as the plants mature. 



Flammula spumosa Fr. 



Pileus pallid light-yellow, disk often darker, slightly fleshy, 

 convex then plane, somewhat umbonate, viscous, flesh pale 

 greenish-yellow.
