372 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 
Resembling Phoma nothum and P. radula. Perithecia one or 
two together, at first concealed, at length exposed, globose, with a 
rather prominent orifice. Spores small, at first hyaline, elliptic 
or obovate, and falling off in that state, at length oblong, brownish 
and uniseptate. The infant perithecia are filled with a compact 
white cellular mass, as in many Spherie when young, and perhaps 
all. Spores at first resembling those of Phoma nothum, which is 
distinguished from every state of this species by its spurious, im- 
perfect, somewhat irregular perithecia. 
407. D. mutila, Fr. in litt. Common on dead twigs of poplar. 
408. D. confluens, n. s. Perithecus confluentibus maculas 
parvas efformantibus depressis subcollapsis ostiolo obsoleto. D. 
mutila, Desm. no. 1880. On twigs of Daphne Laureola, Milton, 
Norths., Mr. J. Henderson, July 1840. 
Forming small, often confluent spots surrounded by the free 
raised cuticle. Perithecia irregular, confluent, depressed, some- 
what collapsed, with no evident ostiolum. Spores oblong, simple 
in our specimens, but probably immature. 
This species has exactly the appearance of some Spherie of 
the section Confluentes, and forms far larger patches than in D. 
mutila, of which it is considered a form by M. Desmaziéres. 
409. D. cespitosa, n.s. Czespitosa nigra; peritheciis globosis 
ostiolo papilleformi ; sporis oblongis. On twigs of ivy, King’s 
Cliffe. 
Bursting in little black tufts through the cuticle. Perithecia 
globose, black ; ostiolum papilleform. Spores pale yellow, hya- 
line, oblong, with a broad distinct border ; endochrome simple, 
without any distinct nuclei; the spores however are doubtless 
immature. 
A well-marked species, resembling externally some ceespitose 
Spherie. The spores in this as in the last exhibit no trace of a 
dissepiment, but we do not doubt that when mature they present 
in both the common type of Diplodia. It differs from D. mu- 
tila in its ceespitose habit. 
410. D. vulgaris, Lév.in Ann. d. Sc. Nat. May 1846, p. 291. 
On twigs of various trees, as at Rudloe, Wilts. 
411. D. tecta, n.s.  Peritheciis tectis gregariis epidermidem 
elevantibus, ostiolo cuticula denigrata polita velato; sporis ma- 
joribus oblongis. On dead leaves of Prunus Lauro- Cerasus : very 
common. 
The leaves are rough with little elevated pustules disposed 
often in dry discoloured patches marked in the centre with a 
shining black speck. Spores oblong; endochrome simple as 
observed at present. 
This is technically a Spheropsis, but as every Diplodia is a
