Clavarias of the United States and Canada 59 



been compared with specimens of C. persimilis from Wales (Dr. 

 Cotton), and seem clearly the same, the spores also having the 

 characteristic shape, but running a little shorter than in Chapel 

 Hill plants. The British plants are described by Cotton as hav- 

 ing the internal structure composed of loosely packed, longitudi- 

 nally-running filaments 3-6;j. in diameter. Our collections vary 

 from stuffed to hollow. 



This species is nearest C. fusiformis, which normally differs in 

 larger size, fasciculate habit, strong taste and different spores. 

 Separate plants of the latter, which are often found among colonies 

 of cespitose ones, are distinguished from C. pulchra by their com- 

 pany, their spores, and their bitter or farinaceous taste. From 

 C. helveola, C. pulchra is easily distinguished by the deeper color, 

 and the very different spores. At the New York Botanical 

 Garden is a collection of this from Bresadola labelled in error C. 

 similis Boud. and Pat. The spores are smooth, 4.5 x 6-6.8[x, 

 shaped as in C. pulchra. Clavaria similis Boud. and Pat. has 

 strongly warted spores. In the Bresadola Herbarium plants from 

 Ithaca, N. Y., (C. O. Smith) determined by Bresadola as C. 

 platyclada Pk. are C. pulchra, as shown by appearance and spores. 

 The type of C. angitstata no longer exists, but a good collection 

 in the Curtis Herbarium from the Schweinitz Herbarium so la- 

 belled has spores like the present species, sub-oval, 5-6.3 x 6.3-7[j.. 

 From the description and figure the real C. angustata may be C. 

 inacqualis.

 September 9, 1915. Clubs hollow. No. 3149. Near same spot as No. 

 1717, August 9, 1918. In some of the groups the stems were distinctly 

 lighter than the club for at least a cm. Others showed less difference.

 Blowing Rock. Coker and party. (U. N. C. Herb.). Some of these 

 plants were very large for this species, but the spores are typical. 



Alabama: Atkinson. (Cornell Herb. ').
