665. A. mycenopsis Fr. Pileus about 12 mm. (% in.) broad, 

 pallid honey-colour, slightly fleshy-membranaceous, somewhat 

 globose then campanulate, at length 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.

Our plant belongs to the variety mentioned by Fries, with adnate gills. 

 Pileus with the margin clothed with little white scales, the remains of the veil ; 

 stem slightly furfuraceous above ; gills adnate, not merely fixed with a tooth.
