378 Rey. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 
The perithecium is but slightly compacted in this species, and 
the part nearest to the cortex is hyaline. The colour of the 
spores is deep sea-blue, exactly the vitreus of the Latins.

428. D. platyspora, n.s. Peritheciis minoribus supra pro 
maxima parte deficientibus; sporophoris validis cum sporis ob- 
longis amplis utrinque obtusis seepe deciduis. On dead twigs of 
plane, Batheaston, Feb. 1850. 
Forming rather minute slightly raised pustules ; perithecia but 
slightly developed, generally if not always deficient above. Spo- 
rophores short, stout, obtuse, simple, often breaking off with the 
oblong obtuse spores, the cavity of which is simple, but the con- 
tents decidedly granular, so as at first to give a granulated aspect 
to the outer wall. 
429. D. microsperma, n.s. Perithecio nigro sub lente pal- 
lido; sporis minoribus oblongis simplicibus. On dead twigs of 
sallows, King’s Cliffe, and in the West of England, C. E. Broome. 
Resembling strongly D. carbonacea, but somewhat larger, and 
distinguished at once by the minute oblong simple spores seve- 
ral times smaller than in that species. In some pustules of this 
species we have seen the perithecia open by a minute fissure, the 
lips of which being elongated by the oozing out of the spores 
make a spurious ostiolum. 
It is given in the first edition of ‘ British Fungi’ with D. car- 
bonacea, at no. 44, as a state of Phacidium carbonaceum, Fr.

429*. D. abnormis, n. s. Perithecio globoso spurio prorsus 
tecto poro pertuso ; sporis breviter fusiformibus luteo-fuscis uni- 
septatis. On shoots of elder, Batheaston, C. E. Broome. 
Perithecia small, entirely covered with the cuticle, globose, 
confused with the matrix, pierced above with a round pore. 
Spores shortly fusiform or lanceolate, uniseptate, yellow-brown. 
This species approaches the type of Diplodia. It is mixed with 
a Phoma, no. 406*, which is more conspicuous, though smaller. 
430. Vermicularia atramentaria, n. s.  Effusa gregaria macu- 
leeformis ; sporis rectis brevibus endochromate utrinque retracto. 
On decayed stems of potatoes: extremely common. 
Forming large ink-black velvety patches, crowded with minute 
perithecia clothed with long straight subulate bristles, connected 
at the base by intricate fibres creeping beneath the cuticle of the 
matrix. Spores minute, linear, rather short ; endochrome re- 
tracted to either extremity. 
Distinguished at once by its straight spores. In general ap-
