Pileus 1-3 cm broad, conic to campanulate or finally convex to 

 plane, sometimes remaining umbonate, glutinous or viscid, appearing 

 as if varnished when dry, color dark green or "parrot green" when 

 young and fresh, soon fading or changing color to ochraceous buff, 

 rufous, tawny, pinkish flesh color, yellow ocher, sordid yellowish, or 

 olivaceous orange, usually drying bright pale incarnate, translucent 

 striate at first, opaque when faded. Context thin, concolorous with the 

 surface, fragile ( but somewhat tenacious because of the thick pellicle ) ; 

 odor and taste not distinctive. 



Lamellae adnate, "light celandine green" at first, soon reddish or 

 "cadmium yellow" to "light cadmium," narrow to broad, subdistant, 

 edges even. 



Stipe 3-7 cm long, 2-5 mm thick, green above or almost over all 

 when very young, soon changing to yellow or orange, in age pinkish 

 like the pileus, slimy-viscid throughout its entire length, equal or 

 tapering upward slightly, hollow. 



Spores 6.5-8(10) X 4-5(6) /*, ellipsoid, smooth, pale yellow in 

 Melzer's reagent. Basidia 28-46 X 6-8 n, 2- and 4-spored. Pleurocystidia 

 and cheilocystidia not differentiated. Gill trama subparallel or very 

 slightly interwoven, hyphae 5-12(20) /* broad, yellowish in Melzer's 

 reagent. Cuticle (an ixotrichodermium ) of narrow (1.2-2.5 fx) 

 hyphae. No hypodermium differentiated. Pileus trama of radial 

 hyphae. Clamp connections none or rare on hyphae of epicutis, more 

 frequently present at base of basidium.
