30 Clavarias of the United States and Canada 



the present species. The spores are oblong-elliptic, 4-5.5 x 8-10[/.. 

 The only important difference appearing from the description is 

 that the stalk is said to be indistinct from the club. 



Clavaria Daulnoyae Quel. (Asso. Francaise Avanc. Sci., 1891, 

 p. 470 (p. 7 of separate), pi. 3, fig. 36) should be compared with C. 

 argillacea, as no differences of importance appear from the de- 

 scription or figure. For a comparison with C. subfalcata see that 

 species. 



The present species has been reported from America by sev- 

 eral authors, as Schweinitz, Berkeley, and Peck, but their records 

 are all quite doubtful. In the Curtis Herbarium a collection by 

 Schweinitz from Salem, N. C, labelled C. argillacea has spores 

 which are minute, 2.3 x 3.7f/., and cannot be correctly determined. 

 Also one from him in the Kew Herbarium so labelled is not this 

 but probably C. helvcola or C. vermiculata. Another collection so 

 called by Peck from the Catskills at Albany are not this but poor 

 specimens of C. ornatipes.
