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, Lev. Ann. d. Sc. Nat. May 1846, p. 296. 

 Sphceria Hedera>, 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. Buxi, DeC, which is also a Sphce- 

 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*. S. geniculata, n. s. Peritheciis globosis tectis, ostiolo 

 conico prominente; sporis curvis sequalibus obtusis diametro 

 4-5 longioribus angulo obtuso affixis. With the last on leaves 

 of Pinus Strobus, C. E. 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, n. s. Peritheciis globosis omnino tectis my- 

 celio furcato-ramoso parco insidentibus ; sporis oblongis diametro 

 triplo longioribus. On dead stems of Equisetum 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 Sph&ria 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, Lev., 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 arc very remarkable. It is probably 

 very common.
