** Gills, flesh and stem yellow at first. 

 326. Cortinarius elegantioides sp. nov. 

 Illustration: Plate LXIX of this Keport. 



PTLEUS 4-7 cm. broad, convex then expanded-plane, cadmium- 

 yellow, orange-fulvous on disk, becoming fulvous-ferruginous in age, 

 glabrous, even, with a glutinous separable pellicle. FLESH thick, 

 whitish or tinged greenish-yellow. GILLS adnate, becoming deeply 

 emarginate and uncinate, close, rather broad, varying pale yellow- 

 ish-ichite, bright citron-yellow or sulphur-yellow, at length ferrugin- 

 ous, thin, edge minutely crenulate. STEM 5-8.5 cm. long, rather 

 stout, subequal, 10-18 mm. thick, dry, spongy-stuffed, yellowish- 

 white or citron-yellow, flesh tinged greenish-yellow, with a margin- 

 ale, subdepressed, subturbinate bulb, which is clothed on the sur- 

 face by the yellow to sub ferruginous, subgelatinous universal veil. 

 CORTINA slight, fugacious. SPORES almond-shaped, elliptical, 

 very tuberculate, 15-18 (rarely 19-20) x 7-9 lnier. BASIDIA 48x12- 

 13 micr., 4-spored. TASTE of flesh tardily but distinctly bitter. 

 ODOR mild. 



Solitary or subcaespitose. On the ground in frondose woods of 

 oak, maple, etc. Ann Arbor, Detroit, New Richmond. September- 

 October. Infrequent. 



Nearly always solitary or of few individuals. Known by its large 

 spores, bitter taste of the flesh and the tinge of green in the yellow 

 color of the flesh, etc. It has the stature of C. multiformis of Cooke 

 (111., PL 708 and 709), but the spores are distinctive. The bulb is 

 not very broad as compared with that of G. fulgcns Fr. ; it is rather 

 soft and decays early. The stem is narrower upwards at first and 

 colors of the stem. It is closer to G. sulfurinus Quel, (sense of 

 Ricken) but differs in its spores, less abundant cortina and the 

 colors of the stem. It is closer to G. sulfurinus Quel, (sense of 

 Ricken), but neither Quelet nor Ricken mention the bitter taste nor 

 llic universal veil.
