Clavarias of the United States and Canada 199 



and the slight spore difference is hardly enough to establish a vari- 

 etal distinction. Clavaria tcnuipcs B. & Br. (Ann. and Mag. Nat. 

 Hist. II, 2: 266. 1848) looks much like the present species. The 

 type at Kew is small and simple, with very slender stems expanding 

 into thick clubs which are a little lobed and have the surface appear- 

 ance of this group. Cotton has a note on the type saying spores 

 "a few, 7 x 3{jl," but the spores are doubtful. A related species is 

 C. dendroides Jungh. ( Fl. Crypt. Java, p. 33, pi. 6, fig. 20, 1838) , 

 later changed to Ptcrula (Nova Acta Soc. Sci. Upsala III, 1 : 117. 

 1855), and also to Thelephora by Leveille (Ann. Sci. Nat. Bot, 

 3rd. ser., 2: 209. 1844). If specimens from Java in Persoon's 

 herbarium are correctly determined, which seems probable, it is a 

 Lachnocladium in the same group with L. cartilagincum and L. 

 semivestitum. The basidia are 2-spored, 4-6[/. thick; the spores 

 smooth, oval, about 7.4 x llpi. A collection of plants in the her- 

 barium of the University of Paris labelled Clavaria compressa 

 Boud. (herbarium name?) also belongs to the same group. Lach- 

 nocladium chartaccum Pat. (Ann. Myc. 5: 365. 1907) from Brazil 

 in the same herbarium has a similar appearance, and so does L. 

 clavarioidcum Pat. (Journ. de Bot. 3: 27. 1889), but these last 

 have smaller spores, "6 x 4[x" in the first and "4-5 x 3[x" in the 

 second. In the Kew Herbarium is a plant from Schweinitz 

 (Salem, N. C.) determined by him as C. palmata Pers. which is 

 probably the present species, but we could find no spores on it.
