3. L. MERISMATOIDES, Schw. Sabcartilagiiious, pale yellow- 

 ish, minutely tomentose. Pileu's very much branched from a short 

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

 apex and somewhat fimbriate. 



On the ground in woods ; rare. Pileus r-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 Schweinitz'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 an intermediate fibrillose stratum. 



Fungi lignatile coriaceous or woody, subperennial, subzonate, 

 entire and of definite shape. 



I. Apus. Pileus sessile, at first resupinate, afterward com- 

 monly pileate reflexed and adnate behind. 

 We have but this section. 



a. Pileus coriaceous, flexible. 

 I. S. RUGOSiuscuLUM, B. & C. Soft-coriaceous. Pileus 

 effuso-reflexed, becoming subreniform 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, Thelephara airata, 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. Flymenium 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, sabimbricate and often laterally 

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