A distinct species, resembling, in many respects, D«edalea 
quercina, but with the habit of Lenzites trabea.

Pileus, 5 inches in diameter, infundibuliform, thin, rigid, 
coriaceous, covered with a thin cartilaginous epidermis, 
rugoso-plicate; the main folds crested with toothed pto- 
cesses, so that in young specimens, the margin is fimbriated, 
red-brown, clothed with a dense, spongy, pale pubescence, 50 
as at first, in great measure, to conceal the folds. Substance 
white, consisting of interwoven threads. Stem 3 an inch 
long and thick, central, spongy, like the pileus. Hymenium 
smooth, with a cartilaginous appearance, following all the nu- 
merous folds and wrinkles ofthe pileus, so as to assume, eS 
pecially towards the margin, a dendroid aspect, at first pale, 
then red-brown, like the pileus. 
In the specimenk, marked n. 2036, the hymenium is sca- 
brous, with a dull aspect, probably from their being acci- 
dentally reversed, and the hymenium, in consequence 
beginning to assume the characters of the pileus, a nof 
unfrequent cireumstance in fungi, and one which requires t9
