9. Ascomyces Trientalis. Berk.

 stratum. 



A scomyces Trientalis Berk, in Cooke's " Handbk. " 

 No. 2234. l 



On Trientalis Ewropma. 



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.
