OVERHOLTS—THE POLYPORACEZ OF OHIO 115 
nium may or may not persist. The best colored representation 
of the fungus is that given by Rostkowius in Sturm, Deutschl. 
Flora 4: pl. 20. The plant is widely distributed and well known 
and has figured largely in American mycology. The following 
illustrations will aid in determinations: Atkinson, Mushrooms 
f. 184-85., Duggar, Fung. Dis. Pl. f. 226., Hard, Mushrooms 
f. 326., and von Schrenk, U. S. Dept. Agr., Div. Veg. Path. Bul.

1832. 
P. hypococcineus Berk. Lond. Jour. Bot. 6:319. 1847. 
Plants annual, sessile; pileus dimidiate, often subungulate, 
5-12 x 6-15 x 1-5 cm., soft coriaceous or corky, buff or orange- 
colored, becoming whitish on drying, minutely tomentose or 
glabrous, azonate, margin usually obtuse; context pale buff, 
becoming carneous when dry, fibrous, sometimes very hard 
when dry, strongly zonate, 0.7-2 cm. thick; tubes 0.5-2 cm. 
long, the mouths orange-colored, becoming brownish on drying, 
angular, averaging 3-5 to а mm.; spores (teste Murrill) smooth, 
hyaline, 3-4 x 2-3 u. 
On dead wood of Quercus and Castanea. Rare. 
Easily distinguished from other species with a predominance 
of red or orange colors by the thick pileus and the long tubes. 
The plant is said to emit a strong odor when growing. The 
type specimens of P. hypococcineus Berk. were collected in 
Ohio by Lea. Р. castanophilus Atk., described from North 
Carolina, is said to be the same plant. 
44. P. sanguineus L. ex Fries, Syst. Myc. і: 371. 1821.

context red or yellowish red, soft and floccose, scarcely more 
than 2 mm. thick; tubes 0.5-1.5 mm. long, the mouths red, 
more or less angular or cireular when young, averaging 2-4 
to a mm.; pileus often attached by an attenuate base and then 
appearing substipitate.
