and the pale yellow, "antimony-yellow" (Ridg.) color of the 

 pileus, are the main features of this good-sized plant. I refer 

 it here with some hesitancy, as the Britzelmayr species are 

 hard to recognize. The spores when examined under the oil- 

 immersion are reticulate-rough and measure 11-13 (14) x 6-7 (8) 

 IJL. The gill-color of the young plant persists to maturity, so 

 that they appear incarnate-tinged even in age. The apex of the 

 young stem is at first tinged with lilac or vinaceous. 



CoRTiNARius MALicoRius Fr. (Dermocybe). Infrequent. 

 Leal, Tolland. Under conifers. 



Cortinarius metarius sp. nov. (Bulbopodium). 



Pileus 4-7 (8) cm. broad; fleshy, convex-expanded, then 

 plane, with a viscid pellicle which is at the very first pale bluish- 

 violaceous, quickly lutescent, then "mustard-yellow," "naples- 

 yellow" or "apricot-yellow" (Ridg.), glabrous, even, the thin 

 margin at first incurved and minutely tomentose; flesh medium 

 thick on disk, tinged at first with violaceous-incarnate tints, soon 

 whitish then lutescent. Gills adnexed, rounded behind, then 

 sinuate-uncinate, narrow, 4-6 (7) mm. broad, crowded, at first 

 incarnate or amethystine, "heliotrope gray" (Ridg.), soon pale 

 "clay-color." Stem 4-6 cm. long, 10-18 mm. thick, subequal 

 above the shallow and broad, marginate-depressed bulb, sometimes 

 compressed-subturbinate, solid, at first more or less violet 

 within and without, soon white then lutescent, bulb covered by 

 remnants of a yellow universal veil, superficially fibrillose above 

 bulb. Odor and taste mild or slight. Spores narrowly ellipsoid, 

 inequilateral, almost smooth, pale yellowish-rusty under micro- 

 scope, 9-12 (13) x 5-6 fx. 



Solitary, on the ground in mountain forests of spruce and 

 fir. Leal, Grand Co., Colorado. August. 



This is exactly halfway between C. calochrous and C. caerul- 

 escens, and these three species offer good material for the "lump- 

 ers" in taxonomy. It differs from C. calochrous, in the dis- 

 tinctly larger spores, and the color changes in the plant; from 

 C. caerulescens, in its smaller spores, the presence of a yellow 

 universal veil, and the narrow gills. The name refers to the 

 limitations imposed by this separation.
