Synonymy : A species was figured and named in 1857 by Berkeley as Chondromyces 

 crocatus Berkeley and Curtis, but not described. The generic name was finally 

 described in 1874. Probably the date of the name should be the date of its description, 

 although it is possible that an adequate labeled illustration should be interpreted as 

 valid publication. 



Etymology : Greek chondros, grain and myces, (fungus). 



Diagnosis: Cysts compactly grouped at the end of a colored stalk (cystophore). 

 Cystophore simple or branched. 



The type species is Chondromyces crocatus Berkeley and Curtis.
