MuRRiLL : The Polyporaceae of North America 005 



ward, often undulate, not becoming truncate, white, at length con- 

 colorous : context soft-corky or woody, radiate-fibrous, concen- 

 trically banded, ochraceous-fulvous ; tubes 0.5-2 cm. long, 5-3 to 

 a mm., brown within, mouths circular or angular, white to gray- 

 ish-brown, edges thin, entire : spores ovoid, obtuse at the summit, 

 attenuate and truncate at the base, verrucose, yellowish-brown, 9- 

 1 1 X 6-8 //. 



This .species occurs on deciduous trees and has the general 

 habit of G. pscndoboletus, 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 [at White Plains, N. Y., May 1897, and on dead 

 sycamore at Fort Lee, N. J., May 1899, and March 1901. 

 Plants collected by Morgan in the Miami Valley, Ohio, Dec. 

 1894, were placed under G. pseudoboletiis 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 oi F. liccidus?" 

 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. 1901, and Feb. 1902. Specimens sent 

 to Kew by American collectors are included there under G. pscn- 

 doboletus. 



4. Ganoderma parvulum sp. nov. 



A very small sessile fungus shining bay above and honey- 

 yellow below. Pileus woody, nearly circular in outline, attached 

 by a point, convex above, plane or convex below, thickest behind, 

 2 X 2.5 X I cm.; surface glabrous, laccate, azonate, slightly tuber- 

 cular, very lightly marked with a few concentric furrows, margin 

 acute : context soft-woody, pale ochraceous, o. 5 cm. thick, with 

 dark horny radiations from the point of attachment : tubes not 

 stratified, 3 mm. long, 5 to a mm., umbrinous within, mouths 

 polygonal, honey-yellow, dissepiments entire, obtuse : spores sub- 

 globose, smooth, pale yellowish-brown, 4 x 5 />«.
