CRATERELLUS 



Plants upright, fleshy, funnel shaped or rarely fan shaped, hyme- 

 nium on outside, smooth or more often rugosely wrinkled at least to- 

 wards the margin. The genus is to all appearances so closely related 

 to Cantharellus that I do not think that we are justified in placing 

 one genus in the Thelophoracece and the other in the Agaricacece as 

 is practiced at present. So close is the relationship in fact that it is 

 doubtful if the two genera can be logically separated. Some species, 

 as the one I have treated here as Cantharellus clavatus, are so inter- 

 mediate as to be placed in Cantharellus by some authors and in Cra- 

 terellus by others. Craterellus cantharellus has not only the same 

 shape and general appearance of Cantharellus cibarius, but also the 

 same fragrance ; while the spores of Cantharellus aurantiacus and 

 C cinnabarinus are pink like the spores of Craterellus cantharellus. 

 If the folds of the hymenium are more or less distinct gills the species 

 should be looked for in Cantharellus, if only wrinkled or rugose or 

 smooth it should be found in Craterellus. As Craterellus is related 

 on the one side to Cantharellus, so it approaches Clavaria on the other, 

 and club shaped forms may be placed in cither genus by different 

 authors. These complicated relationships emphasize the impossibil- 

 ity of placing all related groups in juxtaposition in a lineal arrange- 

 ment of genera. For full treatment of the genus see Burt, Ann. Mo. 

 Bot. Garden 1: 327. 1914. Also see Peck, X. Y. St. Mus. Bull. 2: 

 44. 1887.
