DECADES OF FUNGI.

Hab. On decayed trunks. Panure. 



Pileus 3 inches across, moderately thick, reniform, reddish-umber, 

 corky, radiato-rugose, repeatedly zoned, zones often impressed; mar- 

 gin lobed and crenate. Stem 2-2^ inches high, -^ of an inch thick, 

 irregular, nodulose, cylindrical or compressed, Hymenium yellowish, 

 inclining to orange. 



The pileus is very rugged and crumpled, and contrasts curiously 

 with the yellowish hymenium, which, in consequence, looks almost like 

 a parasite. When the pores grow obliquely, a large portion of the 

 wall is displayed so as to present a very curious effect. — If the hyme- 

 nium of this species is carefully examined, it will be found to differ in 

 no respect from ForotJielhtni. The pores are perfectly distinct on their 

 first appearance, and it is only by confluence and elongation that they 

 assume a character approaching that of Polyporus, or rather of FiskiUm. 

 If resupinate Polypori are to be retained in the genus Polyporus, no 

 good reason can be given why Mesopod and Pleuropod Porothelia 

 should not be retained in that genus. P. rugosiim is connected directly 

 with Pohjporus by P, variabilis, P. pallidus, and several other species of 

 this collection.

igula 



nous. Hymenium white, decurrent ; teeth springing from the edge of 

 a membranous fold. 



A very singular plant, of which only a single specimen was gathered. 



597, TMepkora mbdavceformis, n. s.; brunnea; pileo e spathu- 



lato lobato-subclavpeformi sursiim velutino ; hymenio lineatim rugoso 

 glabro. • 



Hab. On the ground, with n. 84. Panure. 



Brown. Pileus 1-1^ inch high, at first clavato-spathulate, at length 

 deeply lobed, the lobes subclavate, somewhat crenate, velvety above. 

 Stem confluent with the pileus, compressed, with a little white down 



and mycelium at the base. Hymenium decurrent, marked by linear 



folds. 



A very singular species, and perfectly distinct.
