* On one of the specimens of this plant in Dr. Hooker's copy of Mougeot 

 and Nestler's Stirpes Cryptogamicce, there is a minute sample oi Agaricns 

 Hudsoni, Pers., which is most certainly a very distinct and highly curious 

 species ; the stem is nearly if not quite smooth, pale above, dark-brown below, 

 and the pileus is beset with scattered long yellow-brown setie, quite different 

 from any thing that I have seen in the genus and resembling those of Peziza 

 scutellata. Since the above was written 1 have received excellent specimens in 

 Desmaziere's Plant, Crypt. The stem, as in Savcerby's figure, U piLoss lii* 

 the pileu^.
