certain important respects. Bataille (1910) described the trills <>1 //. 

 nemoreus as "blanches, puis creme, a reflet aurore." Bresadola ( L928 

 figured a species which has the gill characters as Bataille described 

 them. Niiesch (1922) also describes the gills of //. nemoreus as essen- 

 tially pale ("blass cremfarbig bis rotlich ocherfarbig oder blasso- 

 range"). He also describes the stipe as whitish to pale ochraceous, col- 

 ors strikingly different from the buff pink to chestnut color of the stipe 

 of H. kauffmanii. Ricken's (1915) description and illustration are in ac- 

 cord with those mentioned above, and Rea's (1922) apparently applies 

 to still a different species because of its spores. J. Lange (1923) de- 

 scribes a form he referred to H. nemoreus (as a variety) as having a 

 white stipe, and the gills paler than the pileus. If descriptions can be 

 relied upon, the dark reddish-brown gills of H. kauffmanii amply dis- 

 tinguish it. 



In the Tennessee collections the lamellae, when dried, are some- 

 what paler than in the type; otherwise there is agreement between the 

 collections. The color of the pileus is ferruginous to vinaceous-ferrugi- 

 nous.

Hygrophorus sublutescens, sp. nov. 



Pileus 1.5-4 cm latus, convexus, viscidus, glaber, subfulvus; lamel- 

 lae latae, confertae vel subdistantes, late adnatae, pallide subalutaceae; 

 stipes 1-3 cm longus, 3-6 mm latus, siccus, deorsum luteus, sursum

Pileus 1.5-4 cm broad, obtuse to broadly convex, surface viscid, 

 glabrous, color a pale dingy tan ( near "cinnamon-buff" ) on disc, grayer 

 toward the margin (near avellaneous or a grayish-pinkish buff), the 

 color duller than in H. discoideus. Context firm, pallid, odor and taste 

 mild. 



Lamellae broad, close varying to subdistant, broadly adnate to sub- 

 decurrent, dingy pinkish buff drying dingy pallid to grayish buff, edges 

 even. 



Stipe 1-3 cm long, 3-6 mm thick at apex, equal, dry, pubescent to 

 fibrillose over lower half, pruinose-scurfy to silky above, typically be- 

 coming lemon yellow over basal part and any part of surface soon 

 bright yellow when touched with KOH. 



Spore deposit white. Spores 6-7.5 X 3.5-4.5 /x, subovoid, smooth, 

 thin-walled, hyaline in KOH, yellowish hyaline in Melzer's solution.
