This species closely resembles G. frondosa in size, habit and 
general structure, but the pileoli are centrally attached and circular 
in form instead of dimidiate and spatulate. It is likewise much 
rarer than G. frondosa both in this country and in Europe.  Per- 
soon’s name seems a very appropriate one, but it is antedated by 
that of Scopoli. Quélet used this species in establishing his genus 
Cladomeris, a synonym of Grifola. In America, the plant is 
reported but rarely. Atkinson found it at Ithaca and refers to 
it in his Studies of American Fungi. Specimens are at hand 
from Pennsylvania, Everhart; Connecticut, Underwood & Earle ; 
and Ohio, Z/oyd; the last accompanied by a fine protogravure of 
the entire living plant.

This species was described from a single pileolus sent to Fries 
from Curtis’ North Carolina collections. It fully warrants the ex- 
pression used by Fries in describing it: ‘‘ Nobilissimus inter omnes 
mihi cognitos Polyporos.” I have seen plants two feet in width 
and over a foot high, with several lobes six to nine inches in 
diameter, They usually grow under oak trees, often between the 
enlarged bases of the main roots, and are in close connection with 
some supply of humus, either from buried wood or very rich leaf- 
Mould. The surface of the pileus is light yellowish-brown, darker 
toward the center, the tubes irregular, light yellowish-brown, 
fragile and somewhat toothed. It is easily distinguished from its 
American allies by the size, color and breadth of its lobes. oly- 
Porus Beatiei Peck and Polyporus subgiganteus 'B. & C. are not 
Specifically distinct. The former was collected in Maryland and 
Well described in manuscript by Miss Banning ; the latter is rep- 
resented at Kew by a pais pileolus collected by Wright in Con- 
necticut.
