Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 375 
strongly collapsed, and presenting the appearance of accurately 
defined excipula. Spores oozing out on the application of moisture 
from a central pore, extremely minute, oblong. 
420. S. leucostigma, Lév. Ann. d. Sc. Nat. May 1846, p. 296. 
Spheria Hedere, Sow., and partly of Fries. Not uncommon on 
dead ivy-leaves, England and Wales. 
420*, S. parca,n.s. Peritheciis minutis tectis collapsis; sporis 
oblongis diametro 4—5 longioribus. On leaves of Abies excelsa, 
Wiltshire, C. E. Broome, Jan. 1850. 
Scattered sparingly on the leaves. Perithecia collapsed when 
dry, so as not to rise at all above the surface, black. Spores 
oblong, subcylindrical, obtuse at either end, but often suddenly 
attenuated at one extremity, 4—5 times longer than their diameter. 
Resembling very much Sph. Buai, DeC., which is also a Sphe- 
_ ropsis, but differing in its collapsed perithecia and narrower 
spores. 
421. S. Strobi,n.s. Peritheciis minutis tectis collapsis; sporis 
linearibus diametro 6-7 longioribus. On leaves of Pinus Strobus, 
Wilts, C. E. Broome, March 1850. 
Very like S. parca, but scarcely so much collapsed. It differs 
in the longer narrower spores, which are never attenuated sud- 
denly. 
421*. 8. geniculata, n.s. Peritheciis globosis tectis, ostiolo 
conico prominente; sporis curvis zqualibus obtusis diametro 
4—5 longioribus angulo obtuso affixis. With the last on leaves 
of Pinus Strobus, C. KE. Broome. 
Perithecia globose, covered by the epidermis, which they pierce 
by means of their prominent conical ostiola. Spores cylindrical, 
curved, obtuse at either end, fixed at an obtuse angle obliquely 
to long delicate sporophores ; sometimes there is a nucleus at 
either extremity. 
422. S. epitricha,u.s. Perithectis globosis omnino tectis my- 
celio furcatu-ramoso parco insidentibus ; sporis oblongis diametro 
triplo longioribus. On dead stems of Hquisetum palustre, Wilt- 
shire, C. E. Broome. 
Perithecia globose, seated beneath a discoloured cinereous spot 
springing from forked septate threads. Spores oblong, about 
three times longer than their diameter. 
We have unfortunately no specimen of Spheria Equiseti, Desm. ; 
but from the author’s remark that it is scarcely different from his 
Phoma albicans, it cannot be the same thing with what we have 
in view. Phoma Equiseti, Lév., is also unknown to us, but the 
description is at variance with our plant, which could scarcely be 
placed in Phoma. The forked septate threads of the mycelium 
with their obtuse apices are very remarkable. It is probably 
very common.
