 Another specimen (Berk, no. 6250), bearing the same name, on 

 culm of Lily, is nothing but immature Diplodia herbarum, Lev. 



In the same cover are two other

specimens, labelled 



One of these, on Rhus, Poughkeepsie (Gerard, N. Amer. Fung. 

 no. 176!) is immature Botryo diplodia compressa (Cooke) Sacc. 



The other, on Ailanthus, Aiken, South Carolina (Ravenel 

 no. 2136!; is immature Botn/odiplodia Ailanthi (Cooke) Sacc.

It is quite different ; B. 



scabrosa is large, rugged, and tuberculose, B. Ailanthi is in small 

 compact pustules, much like those of B. compressa. 



In connection with ,the examination of these specimens it 

 became necessary to investigate Diplodia Wistariae, Brun. (in 



Mycol. iv. 226). The exsiccatum issued under this name 

 by Rouineguere (Eung. Gall. exs. no. 3372!) yielded that species, 

 but also a CamGrosporivm and a Microdiplodia, and on one 

 occasion all three kinds of spores were found apparently in the 

 same pycnidium.
