This species occurs on deciduous trees and has the general 
habit of G. pseudoboletus, from which it differs in being annual and 
Sessile, with a very acute margin and a more rugose surface. So 
far as I have been able to determine, it does not occur in Europe, 
and has not yet been figured. Specimens have been collected by 
Professor L. M. Underwood on decaying oak at Greencastle, Ind., 
Oct. 1894, and lat White Plains, N. Y., May 1897, and on dead 
Sycamore at Fort Lee, N. J., May 1899, and March Igol. 
Plants collected by Morgan in the Miami Valley, Ohio, Dec. 
1894, were placed under G. pseudoboletus and referred to in the 
following note: “As it grows in this region, the stipe is always 
more or less deformed and often wanting; the pilei, when sessile, 
are sometimes imbricated and connate.” In Dec, 1896, it was 
found by C. F. Baker, at Auburn, Ala., and in Nov. 1897, Rev. 
A. B. Langlois collected it near St. Martinsville, La., on decaying 
logs in low woods and marked it “ Perhaps a form of F. /uctdus ?”’ 
Miss Sadie F. Price has recently sent to the New York Botanical 
Garden from Bowling Green, Ky., two specimens of this plant 
collected on oak in Nov. 1gor, and Feb. 1902. Specimens sent 
to Kew by American collectors are included there under G. pseu- 
doboletus.
