 pinkish bufF but then gradually changing to Wood brown or olive 

 brown" in age, or a grayish cast developing before Fading takes p] 

 atomate when Faded, glabrous, moist, hygrophanous, in some the mar- 

 gin becoming Crenate. Context brittle; odor none, taste slight and sub- 

 nauseous. 



Lamellae decurrent, "'Isabella color" to yellowish becoming pallid, 

 and soon darkening to "wood brown" or "benzo brown." (violaceous

 low ). becoming paler in age but not entirely losing the yellow tint and 

 not cinerescent like the pileus, narrowed downward, often flexuous, 

 naked and polished. 



Spores 5-6 x 4-5 /x, subglobose to broadly ellipsoid, hyaline 

 smooth, yellowish in Melzer's reagent. Basidia 30-42 X T-S /;, 4-spored. 

 Cheilocystidia and pleurocystidia none. Gill trama intricately inter- 

 woven, hvphae 7-10 /x broad, hyaline in KOH. Cuticle an hymeniform 

 layer of pear-shaped to vesicnlose, hyaline cells, 10-30 p broad and 

 2()-50 fi long, the layer of cells staggered somewhat in arrangement of 

 the elements but very compact as a layer. Pileus trama of compactly in- 

 terwoven hyphae radially disposed. Cells of carpophore lacking dark 

 colored content (as particles or granules) when mounted in Melzer's 

 reagent. Clamp connections absent.
