 {1J4-3 in.) long, 2 mm. (i lin.) thick, fistulose, very fragile, ascend- 

 ing or twisted, equal, pallid (becoming somewhat yellow) but

665. A. mycenopsis Fr.— Pileus about 12 mm. {Yz in.) broad, 

 pallid honey-colour, slightly fleshy-membranaceous, somewhat 

 globose then campanulate, at le7igth convexo-plane, obtuse or gib- 

 bous with a broadly elevated disc, naked and even at the disc, 

 striate and silky with superficial white-villous down to the middle. 

 Stem 5-7.5 cent. (2-3 in.) long, 2 mm. (i lin.) and more thick, 

 fistulose, sometimes straight (but not tense and straight), some- 

 times undulated, attenuated upwards, yellowish, but white silky 

 with adpressed villous down, obsoletely pruinate at the apex. 

 Gills so ventricose at the middle as almost to be triangular, dis- 

 tant, at first adnexed, at length somewhat free, pallid, the edge 

 delicately flocculose. 



In a plant very like this the gills are adnate, very broad behind, at length 

 plane, becoming whitish-yellow.
