Berk. no. 4208!). This is a Botryodivlodia similar to, if not 



identical with, Diplodia Lantanae, Fckl. Symb. Myc. p. 395, 

 but with the pycnidia evidently immersed in a kind of black 

 stroma. It may be that all species of Botryodiplodia have 

 a Diplodia-ioxm and that this one should be called Botryo- 

 diplodia Lantanae (Fckl.). In a similar way it seems 

 . likely that all species of Diplodia have an earlier small- 

 spored form which would be classed as Microdiplodia; the recog- 

 nition of this probability would help in the understanding of 

 recent discoveries in the latter genus.

This species is certainly a Rhahdospora, not a Phoma; the 

 texture of the pycnidium is very thick and dark. It is accom- 

 panied on the branches by a species of EutypeUa.
