differs materially in structure. Its nearest ally appears to be 
S. Gleditschie. 
From Sph. melogramma as published by Mougeot it differs 
in its pale stroma and elliptic not fusiform sporidia. In 
the plant as published by Fries, No. 441, the sporidia are 
curved. 
100. Sphæria (Byssisedæ) rhodomphala, n. sp. peritheciis 
demum confertis minutis globosis umbilicatis atris plus 
minus, presertim circa ostiolum obsoletum, miniato-pruina- 
tis, sub lente scabriusculis subiculo fusco insidentibus. 
On rotten wood. Ohio. No. 135. T. G. Lea, Esq. 
Scattered, at length much crowded, either free or seated on 
a matted brown subiculum ; perithecia globose at first pow- 
dered with vermilion which is more or less persistent in the 
centre ; ostiolum simple umbilicate; asci somewhat lanceo- 
late pedicellate; sporidia lanceolate constricted in the centre 
With a single septum, and containing one or sometimes two 
nuclei, 
A pretty species but rather difficult to place, as the subi- 
€ulum is sometimes entirely wanting and the perithecia are 
rather pulverulent than villous. It has almost equal claims 
to take its place amongst Denudate, Villose and Byssi- 
sedæ,
