28. C. decolorans Fr.— Pileus 4-6 cent. {\%-i}i in.) broad, 

 wholly persistently yellow, fleshy, convex then flattened, somewhat 

 gibbous, equal, even, smooth, viscous ; flesh thin, Jirm, white. 

 Stem 5-7.5 cent. (2-3 in.) long-, 6-8 mm. (3-4 lin.) thick, stuffed, 

 equally attenuated, shifting white, smooth above the somewhat 

 persistent medial cortina. Gills sinuato-adnexed, crowded, thin, 

 6 mm. (3 lin.) broad, juiceless, purplish theri soon cinnamon. 



The gills are unchangeable when bruised. Easily mistaken for a thin form 

 of C. varius, differing, however, in the thinner unicolorous pileus, in the stem 

 being more slender, externally rigid, polished, without a bulb, and smooth 

 with exception of the cortina.

29. C. porphyropus Fr. — Pileus 4-7.5 cent. (1^-3 in.) broad, 

 livid-light yellowish or clay-colour, unchangeable when touched, 

 fleshy, very thin at the margin, convexo-plane, obtuse, even, 

 innately streaked, viscid ; flesh thin, soft, whitish, soon becoming 

 Purple-lilac when broken. Stem 5-10 cent. (2-4 in.) long, about 

 6 mm. (3 lin.) thick, stuffed, at length hollow, somewhat bulbous 

 or rather equally attenuated from the thickened base (sometimes 

 equal), fragile, externally and internally violaceous-lilac, soon 

 becoming pale, even whitish, but soon becoming violaceous-lilac 

 again when touched. Cortina inferior, fibrillose. Gills rounded 

 or emarginate, somewhat crowded, rather broad (4-8 mm., 2-4 

 lin.) purplish then watery cinnamon, becoming purple again 

 when touched. 



It approaches C. purpurascens, but the gills are crowded in that species.

 cious. Gills attenuated or broadly emarginate, with a small 

 very thin decurrent tooth, plane, somewhat distant, lilac then
