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 Sphceria 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. confluenSj n. s. Peritheciis confluentibus maculas 

 parvas efibrmantibus depressis subcollapsis ostiolo obsolete. 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 Sphcerice of 

 the section Confluentes, and forms far larger patches than in D. 

 mutila, of which it is considered a form by M. Desrnazieres. 



409. D. caspitosa, n. s. Csespitosa nigra ; peritheciis globosis 

 ostiolo papillseformi ; sporis oblongis. On twigs of ivy, King^s 

 Clifl'e. 



Bursting in little black tufts through the cuticle. Perithecia 

 globose, black ; ostiolum papillseform. 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 csespitose 

 SpharicB. 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 difi'ers from D. mu- 

 tila in its csespitose habit. 



410. D. vulgaris. Lev. 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 Planus 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 Sphceropsis, but as every Diplodia is a
