Illustration: 

 Fig. 71. 



Pileus 5-15 mm broad, convex, then broadly convex to plane, the 

 disc not depressed, "scarlet," "flame scarlet," to "Mars orange." hy- 

 grophanous, fading to "antimony yellow," glabrous, appearing silky on 

 drying, distinctly viscid or glutinous, margin striatulate when fresh. 

 Context thin, fragile, concolorous with the surface; odor and taste mild. 



Lamellae adnate to adnexed or with a decurrent tooth, "orange 

 buff" to "bittersweet orange," close to subdistant, broad and somewhat 

 ventricose, edges even. 



Stipe 1.5-5 cm long, 1-3 mm thick, at first red above, yellowish or 

 whitish below, fading to yellow over all in age, fragile, equal or taper- 

 ing downward, glutinous or viscid, stuffed, becoming tubular. 



Spores 7-10.3 X 4-5(6) yu, ellipsoid, smooth, yellowish in Melzers 

 reagent. Basidia 30-45 x ,5-8 ^, 4-spored. Pleurocystidia and cheiloc) s- 

 tidia none. Gill trama of parallel to subparallel hyphae, yellow in Mel- 

 zers reagent, cells 6-15 /x broad. Cuticle an ixocutis, of repent, colorless 

 hyphae, at times the surface hyphae are more or less erect. Hypoder- 

 mium none. Pileus trama of radial hyphae. Clamp connections present 

 on the cuticular hyphae.
