*** Gills, flesh or stem yellow, fulvescent, or ferruginous. 

 338. Cortinarius fulgens Fr. • 



Epicrisis, 1836-38.

Gillet, Champignons de France, No. 223 (doubtful). 



P ILEUS 6-15 cm. or more broad, firm, broadly convex to plane, 

 bright orange to orange-fulvous, disk orange-ferruginous, somewhat 

 virgate streaked, very viscid when moist, margin incurved at first. 

 FLESH thick, yellowish then alutaceous. GILLS dilute yellow then 

 deep ferruginous-orange, emarginate, broad, close, edge entire. 

 STEM 1-7 cm. long, 15-25 mm. thick, firm, solid, yellow, covered by 

 the dense rusty-stained fibrils of the cortina, equal or subequal 

 above the large, depressed-mar ginate bulb. SPOKES almond-shap- 

 ed, abruptly apiculate, 9-12 x 6-7 micr. ODOll and TASTE mild. 



Solitary or subgregarious. On the ground in open beech woods. 

 Aim Arbor. September. Infrequent. 



This large species is here interpreted in the sense of Fries as 

 expressed in his unpublished plates at Stockholm. Authors are 

 not agreed as to its identity as shown by their plates, different spore- 

 measurements, etc. Fries' plates show larger plants than indicated 

 in his description, although he says they are "showy, robust and 

 golden." His figures of this and the following species show that 

 the virgate appearance of the pileus of G. fulgens was to his mind 

 one of the essential differences. The microscope has shown that 

 probably several species are included under the old ones. Speci- 

 mens from Bresadola with spores 15-18x9-10 illustrate this view. 

 G. phyllophilus Pk. (N. Y. State Mus. Bull., 157, 1912), seems to 

 approach our specimens rather closely. 



339. Cortinarius f ulmineus Fr. var. sulphureus var. noV. 



Epicrisis, ls:;i;-38. 



Illustration: Plate LXXI of this Keport. 



PILEUS 5-10 cm. broad, convex then plane, sulphur-yellow, 

 scarcely changing to darker, sometimes with spot-like scales on the 

 disk, viscid, even, glabrous. FLESH thick on disk, yellow or yellow- 

 ish-white, rather soft. GILLS adnate, then emarginate, moderately
