: picea (Pers.) Sacc. is also a Phomopsis (Phomopsis picea, v. 
Héhn.), though not British; therefore Berkeley’s specific name 
cannot stand. The resemblance of P. piceata to Ceuthospora 
concava, Desm. (Ann, Sci. Nat. 1847, vii. 17) is very close, but 
the latter is much broader (about Qi times) and has different 
spores; nevertheless it is — not to suspect that they are 
mere forms of each other

On twigs of Acer Pseudoplatanus. Cooke says that it was 
associated with Calospora Platanoidis, Niessl, and suggests that 
it is the pyenidium cf that species, but analog would make it 
rather to belong to a Diaporthe. The British specimens seem 
tu incline somewhat towards Fusicoccum.

On twigs of Prunus Laurocerasus, P. lusitanica. Possibly the 
pycnidium of Diaporthe viridarii, Sacc. Some authorities give 
the spores a greater width (Cooke, 45 »; J. W. Ellis, 3-4 «), but 
I find them as stated. When the twigs of P. lusitanica are 
the epidermis around the pyenidia retains its colour, but there 
is no difference otherwise between Cooke’s two species.
