Thelephora multipartita Schw. 



Brownish-cinereous, pileus subcoriaceous, subinfundibuliform, 

 many times parted and divided even to the stipe, the laciniae 

 dilated above and more or less incised. 



Stipe short, glabrous. 



Hymenium nearly even, glabrous, brownish, sometimes paler 

 at the margin. 



On the ground in woods. River Forest. Harper. Plants 

 about 2.5 cm. high, the thin fiat branches dilated above and 

 nmltifid. 

 Thelephora vialis Schw. 



Coriaceous, when young somewhat fragile, becoming hard with 

 age, pilei variously shaped, imbricated and dimidiate, and regular 

 or many confluent into one, laciniate-multificl, 2.5 to 5 cm. long 

 or much smaller, often cup-shaped, above agglutmate-fibrillose- 

 plicate, smoky yellow. 



Stems separate or concrescent, thick or thin, short or long. 



Hymenium plicate-venose, from pallid-yellow to fuliginous. 



On the ground in woods. Millers and Glen Ellyn. The plant 

 forms rosettes 6 to 8 cm. in diameter. The spores are pallid- 

 fuliginous, globose but somewhat irregular in outline, 7 to S u. 

 in diameter. 

 Thelephora palmata Scop. 



Brownish-purple, pubescent, fetid; pileus soft-cornicemis, very 

 much branched, the branches palmate, flattened, sub-fastigiate, 

 fimbriate and whitish at the apex. 



Hymenium even; stipe short, simple. 



Woods, Glen Ellyn, Winficld and Glencoe. Plants rusty- 

 brown, the tips of the branches white. Spores very irregular, 

 angled, rough, about 7 x 10 /a. 

 Thelephora Schweinitzii Pk. (Plate XXII, Fig. 1.) 



Caespitose, white or pallid; pileus soft-coriaceous, much 

 branched, the branches flattened, furrowed and somewhat 

 dilated at the apex. 



Hymenium even, becoming darker colored. Stems variable 

 in length, often connate or fused into a solid base. 



Grassy places in woods, July to September. Common. Often 

 in masses 10 to 15 cm. in diameter. When young, the plants are 

 pure white and quite conspicuous among the decaying grasses and 

 leaves.
