P. perennis to wliich it is related. The pores are not at all decur- 

 rent and the pileiis is nearly horizontal. The umbilicus, when 

 present, is very small. 



POLYPORUS HUMILIS Peck, 



Pileus soft, smooth, spathiilate, suborbicular or reniform, white ; 

 pores small, subrotund, white ; stem lateral, thick, rather long, 

 externally soft and elastic, within firm, whitish, sometimes becom- 

 ing brown. 



Plant l'-2' high, pileus 8" -12" broad, stem 2 "-3" thick. 



Half buried sticks and branches in open woods. Sterling.

The thick stem, with its soft spongy external coating and hard 

 rigid center, is a peculiar character. 



PoLYPORUs RHiPiDius Berk. 



Old logs and stumps in woods. Sterling. August. 

 Without an examination of the hymenium, this might easily be 

 taken for Panus stipticus. 



PoLYPORUS MACULATUS 71. Sp, 



Pileus of a cheesy consistence, broad, flattened, sometimes con- 

 fluent, sessile or narrowed into a short stem, slightly uneven, 

 white or yellowish-white, marked with darker zones and watery 

 spots ; pores minute, subangular, short, whitish, sometimes tinged 

 with brown ; flesh white. 



Pileus 4:'-6' broad, 6"-8" thick. 



Prostrate trunks of trees in woods. Worcester. July. 



In texture and shape this species is related to P. sulphureus, 

 but the pores are smaller than in that species. The plants are 

 sometimes caespitose, sometimes single. The spots in the dried 

 specimens have a smooth depressed appearance. 



PoLYPORUS AURANTIACU8 n. Sp. 



Pileus soft, thin, sessile, dimidiate, sometimes confluent, fibrous- 

 toinentose, obscurely zoned, orange color; pores small, angular, 

 acute, unequal, at length lacerated, pallid inclining to orange; 

 flesh tinged with orange, obscurely zoned.
