140 Clavarias of the United States and Canada 



Spores (of No. 2845) about cinnamon-buff (Ridgway), rod- 

 elliptic, with a curved tip, characteristically marked with longi- 

 tudinal striations, 3.3-3.8 x 11-13^. Basidia (of No. 2862) 7.4-8|/. 

 thick, 4-spored; hymenium 55-65(jt. thick; hyphae 3-8[/. thick, clamp 

 connections present. 



Common in upland woods. Easily distinguished from C. 

 botrytis by the wine colored instead of rose-pink tips, which grow 

 deeper in age instead of lighter as in the latter species ; also by the 

 different taste, less firm and brittle flesh, and different spores. 

 The striate spores separate it from all other species. Clavaria 

 obtiisissima has spores of like shape, but without the striations, 

 and the plant has stouter branches without wine colored tips. 

 A peculiarity of the plant is the spotted appearance that almost 

 always results from the gnawing of grubs as maturity is passed. 

 Another is the open way in which the branches dry. The species 

 has been much confused with C. botrytis, which see for discussion. 

 Migula's figure referred to below shows by the striate spores that 

 he confused this species with C. formosa. Compare also C. pallida 

 as interpreted by Maire (Bull. Soc. Myc. Fr. 27: 451. 1911). The 

 variety frondosarum Bres. of C. rufescens (in Schulzer, Hed- 

 wigia 24: 148. 1885) is said to differ from the species in the tips 

 not being red and in the white stem. It may not belong to this 

 species. Quelet's interpretation of the species seems to be the 

 same as ours. He speaks of the purplish tips, and the spores also 

 agree. Clavaria holorubella is not to be distinguished from this 

 species by the description and the spores are identical. We find 

 them (in the type at Ithaca) striate, 3.7-5 x 10.5-13. 3[x.
