On ivy leaves. Aberystwyth. 



Scattered over the upper surface of the leaf, punctiform, black, strongly

On leaves of Ahies excelsa. Jan. "Wiltshire. 



Scattered sparingly on the leaves ; perithecia collapsed when dry, so as not 

 to rise at aU above the surface, black ; spores oblong, sub-cylindrical, ob-

 an obtuse angle. — B. 4' Br. Ann. N.H. no. 421*. 



On leaves of Pinus strobus, with S.strobi. 



Perithecia globose covered by the epidermis, which they pierce by means

 times there is a nucleus at either extremity.—^. dsBr.
