PILE US --5 cm. broad, convex-plane, with viscid, separable 

 pellicle, sulphur-yellow, sometimes greenish-tinged, fulvous on 

 center, paler od margin, glabrous, even, sometimes obscurely vir- 

 gate, provided when young with a yellowish-white cortina on the 

 margin. FLESH yellowish or greenisli-yellowish, rather thin. 

 GILLS adnate-emarginate or decurrent by a tooth, close, moderate- 

 ly broad, sulphur-yellow or greenish-yellow at first, finally pale 

 ferruginous. STEM 3-7 cm. long. 3-7 mm. thick, often slender, 

 equal, hollow by a narrow tubule which is at first stuffed, fibrilloSi . 

 yellowish above, soon sordid rusty-fulvous toward base. SPORES 

 elliptic-oval, smooth, 6-8x4-5 micr.. contracted toward one end. 

 CYSTIDIA on sides and edge of gills. GO-TO x 12 micr.. lanceolate- 

 ventricose. ODOR slight or of radish.

This is probably as common as any of the Flammulas bul is to 

 be sought in the regions once covered with hemlock or pine. The 

 color of the pilens and flesh varies from youth to age, becoming 

 darker or more dingy, and individual specimens vary from sulphur- 

 yellow to greenish-yellow but are never as green on the margin of 

 the cap as /■'. polychroa. The usual distinguishing marks are the 

 sulphur-yellow margin of the cap. its fulvous to tawny disk, the 

 marked viscidity, the slender, fibrillose stem and the yellowish or 

 citron-yellow flesh. The spores have a rather characteristic shape 

 as compared with nearly related species.
