Spheropsis at an early stage of growth, it requires some caution 
in assigning the genus where the spores present the usual type 
of the young spores of Diplodia. 
412. D.consors, n.s. Peritheciis gregariis tectis ; epidermide 
polita nigrefacta centro dehiscente albida ; sporis minoribus ob- 
longis. Growing on the same leaves with D. tecta, but gene- 
rally in distinct patches and equally common. 
Forming broad patches. Perithecia covered, indicated by 
small shining black dots which open in the centre by an irre- 
gular orifice, the edges of which are white. Spores only two- 
thirds of the length of those of D. tecta, oblong-elliptic, uni- 
septate. 
The two species are extremely common, but we cannot find 
any notice of them. 
413. Hendersonia macrospora, n.s. Peritheciis omnino tectis ; 
_sporis rectis anguste lanceolatis 5-8-septatis. On dead twigs of 
Philadelphus coronarius, Apethorpe, Oct. 1848. 
Entirely concealed by the cuticle, which is very slightly raised. 
Perithecia globose. Spores narrowly lanceolate, 5-6-septate. 
Distinguished by its concealed habit and long fusiform spores. 
413*. H. arcus,n.s. Peritheciis denudatis globosis, sub mi- 
croscopio chalybeis; sporis arcuatis medio incrassatis 3-septatis. 
On box twigs, Batheaston, C. E. Broome. 
Perithecia globose, at length naked, subgregarious, black, but 
when seen by transmitted light steel-blue. Sporophores branched ; 
spores elongated, curved, swollen in the centre, attenuated at 
either extremity, hyaline, triseptate. 
Resembling closely in form and colour Spheria pulicaris, with 
which it often grows. The fructification is however totally dif- 
ferent, and can scarcely be a transformation of the asci of that 
species. 
414. H. mutabilis, n. s. Pustulis depresso-ellipticis intus cel- 
lulosis sporis oblongo-ellipticis 3-4-septatis articulis hic illic 
longitudinaliter divisis. On dead twigs of plane, Batheaston, 
C. H. Broome. 
Pustules small, scarcely bursting the cuticle, elliptic, black, 
with a few central cells besides the large cell or perithecium, 
which occupies the whole of the pustule. The central cells are 
developed later than the main cell, so that the spores in the 
former are simple or uniseptate, while im the larger cell they 
have acquired a much larger size, and have three or four trans- 
verse septa with the articulations here and there divided. 
A section with the central cells and the large one surrounding 
them filled with spores in different stages of development pre- 
sents a very curious appearance under the microscope.
