Type: in Herb. Schweinitz, Acad. Nat. Sci., Phila. 



Pileus coriaceous, solitary, infundibuliform or divided to the 

 stem into triangular divisions or flabelliform, fibrillose, drying 

 pallid or tawny-olive, darker at center of the cup or at base of 

 the divisions, margin lacerate; hymenium usually hair-brown, 

 sometimes pallid ; spores melleus to umbrinous under the micro- 

 scope, angular-tuberculate, 6-7 x 4|-5)u. 



Fructification 6 mm.-2J cm. high; pileus 5 mm.-2| cm. broad; 

 stem 3-15 mm. long, 1-1^ mm. thick. 



In moss in wet places and on humus. Ontario to Alabama 

 and westward to Kansas. 



The differences in form of the pileus of T. regularis are well 

 shown by the type in Herb. Schweinitz; this type consists of 

 three fructifications, two of which are infundibuliform, the 

 third and largest, flabelliform. The hymenium is sometimes 

 merely pallid, as in the case of the specimen which is the T. 

 pannosa of Schweinitz, Syn. N. Am. Fungi, No. 606, but is not 

 T. pannosa Fr. The cotypes of T. Ravenelii and T. hiscens 

 agree in all respects with the authentic specimen of T. regularis 

 in Curtis Herb. Specimens of T. regularis which have the pileus 

 infundibuliform and little cleft are suggestive of small specimens 

 of T. caryophyllea but differ from the latter by the thicker pileus
