104 Clavarias of the United States and Canada 



Spores (of No. 2404) pure white, angular-tuberculate, 3-3.8 x 

 4.6-7.4 (a. Basidia 6-7\x thick, 4-spored; hymenium (of No. 4433) 

 40-60{a thick; threads of flesh 2-3jji thick, parallel, clamp connec- 

 tions present. 



In drying the plant does not become ochraceous or brownish, 

 but remains white or nearly so. The photograph shows the habit 

 of branching better than words. Small plants of this species are 

 similar in size, shape and color to C. Kunzei, but are easily dis- 

 tinguished from it by absence of tomentum on the stalks, smell of 

 old ham, and larger, nodular spores. 



There is no reasonable doubt that this is C. angulispora Pat., 

 described from Venezuela on earth in woods, which agrees in every 

 important respect except that he gives the basidia as 2-spored. 

 The spore drawings show the same surface as ours and the shape 

 may be easily matched in our collections. 



Lachnocladium dubiosum is certainly this species. The appear- 

 ance of the type in Bresadola's herbarium is identical, and the 

 spores also agree.
