 14 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



pean exsiccati in the Missouri Botanical Garden Herbarium there 

 are no specimens labelled C. aurea. 



Concerning C. aurea in Great Britain, Cotton and Wakefield 

 state: "With regard to C. aurea it is difficult to dogmatise as to 

 • its identity. The English specimens so named consist as stated 

 above for- the most part of C. jlava, but a few which as far as 

 can be seen from herbarium material only differ in possessing 

 shorter spores maybe distinct also in other characters, and these 

 may possibly represent the C. aurea of Fries. Until the Swedish 

 species of Clavaria have been critically worked out it is advisable 

 not to attempt to describe the plant or list the species for 

 Britain."
