Berkeley Extremely tender. Pileus 4 — 6 lines broad, at first sub- 



cylindric, granulosa, under a lens, apex brownish shaded into cinereous 

 towards the margin, at length plano-convex ; margin folded. Gills 

 rather distant, free, powdered with the black sporules, the extreme 

 margin white, narrow ; at length aj)pearing like mere wrinkles. Stem 

 H inch high, not 1 line thick, white, nearly or quite smooth, hollow, 

 attenuated upwards, furnished with a cup-shaped more or less distant 

 permanent ring. A most distinct and elegant species. There is a 

 figure in Pers. Mijc. Eur. v. 3. t. 20. /! 1, of an Agaric possibly identical 

 with this, but darker and of a different form, but the text is not yet 

 published, nor is there even a name assigned to it, so that I am unable 

 to form any decided opinion. As 1 found it in company with my friend 

 Mr. J. Henderson of Milton, than whom there are few more active and 

 intelligent practical botanists, I am desirous that this most beautiful 

 though minute plant should bear his name.
