3. L. MERiSMATOiDES, Scliw. Subcartilaginous, pale yellow- 

 ish, minutely tomentose. Pileus very much branched from a short 

 stipe; the branches numerous, straight, slender, dilated at the 

 apex and somewhat fimbriate. 



On the ground in woods; rare. Pileus 1-2 inches in height, 

 the stipe branched from near the base ; the branches long, slender, 

 fastigiate, soon flattened or angular and dilated at the apex. Where 

 the pale yellowish tomentum disappears it leaves naked the reddish- 

 brown subcartilaginous substance beneath. This is Schwelnitz's 

 Clavaria merismatoidcs, N. A. Fungi, No. 1044. 

 Genus IV. — Stereum, Pers. 



Hymenium definitely inferior, even, glabrous, separated from 

 the cuticle of the pileus by art intermediate fibrillose stratum. 



Fungi lignatile coriaceous or w^oody, subperennial, subzonate, 

 entire and of definite shape. 



1. Apus. Pileus sessile, at first resupinale, afterward com- 

 monly pileate reflexed and adnate behind. 



We have but this section. 



a. Pileus eoriaeeous, flexible. 

 I. S. RUGOSiuscULUNf, B. & C. Softcoriaccous. Pileus 

 effuso-reflexed, becoming subreniforni with a narrow base, glabrate, 

 finely wrinkled, brownish; the margin paler and velvety. Hymen- 

 ium even, dark brown; spores brown, subglobose, echinulate 

 .010-. 01 2 mm. in diameter. 



On old trunks; rare. Pileus 1-2 inches in breadth, projecting 

 ^ of an inch. The dark pileus is soft, smooth and pliant when 

 fresh, contracting somewhat and becoming finely wrinkled when 

 dry; the growing margin is pale and velvety-tomentose ; the to- 

 mentum disappears on the older portions of the surface. It is 

 possible this is the No. 638, Thelephora atrafa, Sw. of Schweinitz's 

 N. A. Fungi. 



2. S. VERSICOLOR, Swartz. Coriaceous-membranaceous, thin. 

 Pileus effuso-reflexed, becoming free, expanded, sessile with a 

 narrow base, villous-tomentose, with numerous narrow concentric 

 zones, variously colored; margin acute, entire or variously lobed 

 and incised. Hymenium glabrous, even, pallid or pale yellowish. 



On fallen trunks and branches of every kind of wood ; very 

 common. Pileus usually 2-3 inches in length and breadth, fan- 

 shaped or somewhat reniform, subimbricate and often laterally 

 connate. The colors are gray and ochraceous, varying to ferrugin-
