54 Clavarias of the United States and Canada 



easily distinguished by its shining yellow, sharply defined stem; 

 solid, delicately channelled, pale and brittle club, lack of taste and 

 odor and rather large, smooth, subspherical spores. From C. 

 fusiformis, which is apparently nearest and has the same spores, 

 it is separated by most of the characters just mentioned as well as 

 by the typically single habit. Usually only one to four are found 

 in one place and the individuals are separated by several inches. 

 The only other simple plant with about the right spores is C. pel- 

 Incidula Britz. (Hymen. Siidb., p. 290, fig. 38). Whether it is 

 the same or not cannot be gathered from the incomplete descrip- 

 tion, but the bases are flexuose and the clubs thickened upward 

 and no distinct stem is mentioned. Clavaria lutco-ochracca differs 

 in darker and less distinct stems, smaller spores and basidia and 

 different appearance in the dried state. ( See specimens in the 

 N. Y. Bot. Gard. Herb.). Clavaria Daigremontiana Boud. with 

 longitudinally ridged clubs is easily different (see note under C. 

 helveola).
