Spores narrow-oblong or somewhat obovoid, acute at base, 
pet in profile view, “9-11. x 2-25 ph x 3 pu, Sacc.); sporo- 
Saag crowded, filiform, usually straight, about 15 x 1 yp. 
On scales of cones of Picea excelsa, Malvern “ar Dolgelley 
(Ellis) ! The pycnidium of Diaporthe occulta, Nits., which has 
previously been recorded as British. The spores resemble much 
those of Cytospora stictostoma, Grove, but are longer and there 
is no cytosporoid stroma (as in that species), though the part of 
the scale where the pycnidia occur tends to be stained with black. 
The pycnidium is imperfect above.

Desm. in Ann. Sci. Nat. 1847, viii. 16. 
Spores fusoid-oblong, more acute below, 7-8 x 2-2°5 p; 2 geoa 
phores subulate, inflated below, 12-15 x 25-3 yu. (Fig. 19.) 
On fallen petioles of Robinia Pseudacacia; recorded also on - 
petioles of Cytisus and Gleditschia, in other countries. Saccardo 
gives the sporophores as ‘‘ filiform, 20-23 x 1 pn,’ but these 
prone re Bag eee B-spores. There seems no reason why this 
obinia should not be considered identical with 
Phividaie Pseudacaciae, Trav., which is found on the branches 
of Robinia, and is the pyenidium of Liaporthe fasciculata, Nits. 
The form on Sophora, sometimes included here, belongs to 
P. Sophorae (see no. 63). Probably all these € species on 
rove are merely forms of those on the branches of the same 
lant: see nos. 16 and 69. Vhoma petiolorum, Eckl. (Symb. 
Myce. p. 132) is quite different, and appears to be the pycnidium 
of a Mita I have found both the Phoma and the Phomopsis 
on Robinia petioles, the former with a Pleospora akin to 
P. herbarum. 
42. ¥. Soper Grove. Phoma Phaseoli, Desm. in Ann. 
Sci. Nat. 1836, vi. 
Spores sheds Nine or subelavate-fusoid, rather acute at the 
ends, 7-9 x 2- ee an sporophores eylindric-subulate, about 15 x 
2-2°5 p. (Fig. 20. 
On old ae of Phaseolus. No oe a: the pycnidium of a 
Dia Fg sktind possibly D. Phaseolorum, C. FE. The specimens 
esmazieres (Pi. Crypt. no. 843) seem i be the same as the 
wien ones, but younger; the pyenidium is often imperfect and 
thev are in any case a Phomopsis, but the f. Lepidti, Sacc. is 
different.

On the under surface of dead Rose leaves. This is a doubtful 
species ; the measurements have been taken from Berkeley’s 
= inal specimens. e spores were often seen constricted as
