ASCOMYCES. 405 



9. Ascomyces Trientalis. Berk. 



Spots orbicular or irregular, arising from a reddish 

 stratum. 



Ascomyces Trientalis — Berk, in Cooke's " Handbk," 

 No. 2234. ' 



On Trientalis Europaia. 



Name — From the host plant. 



I am informed on very competent authority that 

 nothing but Tubercinia trientalis is now to be found on 

 Mr. Berkeley's original specimens, but this is no sufficient 

 reason for suppressing the species, seeing with what diffi- 

 culty specimens are preserved.
