texture soft, spongy, the surface velvety. In its color and context 

 nature it is very much the same as Polystictus tomentosus. There 

 are no setae on the gills, however. The spores are smooth, colored, 

 elliptical, 6x12 mic. It has a short, velvety stem, usually central, 

 though I have rarely seen excentric specimens.

HISTORY. This plant was found by Berkeley in Hooker's herbarium. 

 The specimen came from B. D. Greene, Tewkesbury, Massachusetts. 17 It was 

 of much interest to Berkeley as the second known species of the genus. He 

 gave a good figure of it (by Fitch), and the plant has never had a synonym, 



17 Who B. D. Greene was I do not know, excepting that this species was named for him. 

 Neither do I know who named it, though Berkeley published it. The original label in Hooker's 

 herbarium is in a writing I do not recognize, "Cyclomyces Greenii, Boston, U. S., B. D. 

 Greene." It was published from Tewkesbury, Mass. As far as I have noted, this is the only 

 plant sent to Kew from "B. D. Greene."
