 206 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



more or less deeply and unequally into a few lobes, sometimes 

 divided to the stem and spreading so as to appear dimidiate, 

 very often deeply divided and subdivided into many narrow 

 and spreading divisions more or less dilated and whitish at the 

 apex; stem erect or incurved, equal or tapering upward, some- 

 times branched above, drying walnut-brown or pallid, villose; 

 hymenium inferior, glabrous, even, fawn-color or vinaceous 

 drab; spores unbrinous under the microscope, tuberculate, 7-9 

 X 5-6/x. 



Fructification 1^-3 J cm. high, 1-3 cm. broad; stem 1-2 cm. 

 long, 1-3 mm. thick. 



On ground in groves of broad-leaved trees, especially under 

 oak. New York and Pennsylvania to Illinois. July to Sep- 

 tember. 



The upper surface of the pileus was originally described as 

 glabrous, but it is minutely pubescent under a lens, or sometimes 

 fibrillose. This species is very perplexing by its close relation- 

 ship to T. regularis. The multipartite pileus is the only char- 

 acter which seems available to separate collections of the former 

 from the latter species. If a given collection consists wholly 

 of specimens with pileus many-parted and subdivided into nar- 

 row divisions, or if it contains some such specimens in addition 

 to others with more regular infundibuliform pileus, I refer the 

 collection to T. multipartita, as in the cases of the collections 

 cited below from C. O. Smith and Dr. C. H. Peck respectively. 

 As yet, I know of no characters by which to assort and separate 

 into their respective species specimens mixed together of typical 

 T, regularis and those specimens of T. multipartita which have 

 the pileus infundibuliform or merely cleft more or less deeply 

 and unequally into a few lobes. Therefore it is my opinion 

 that T. multipartita is a variety of T. regularis, but the collec- 

 tions which have so far been submitted to me, have been com- 

 posed of too few fructifications to assure me that this opinion 

 is correct.
