exercised in the examination, the terminal cilia may be overlooked.

10. VALSA cERATOPHORA, Tul. Erumpent, splitting the epidermis 
in a somewhat stellate manner. Perithecia globose, with very long 
necks. Asci numerous, linear-oblong, 8-spored. Sporidia minute,

fallen Elm-branches. Fife House, Whitehall, Janaary, 1866. (Fig. Ta, 
section of group of perithecia; 4, ascus and sporidia; c, free sporidia,

* VALSA TETRATRUPHA, B. and Br., var. simplex. Recently I col- 
lected specimens of a Spheria on the slender twigs of aWillow, which ap- 
peared to me to be so distiuet from every described species with which I 
was acquainted, that I named it provisionally S. ewstegie, and some spe- 
cimens were sent to correspondents under that name. Mr. Broome, how- 
ever, is disposed to regard it as a form of Falsa tetratrupha. The peri- 
thecia are in the majority of instances single and scattered, occasionally 
two or three are confluent. The asci are cylindrical and 8-spored. 
Sporidia uniseriate, triseptate, but without any indications of transverse 
septa. Indeed, nothing can at first sight appear more distinct than 
this form, and the species to which it is referred. Mr. Broome has a 
far better knowledge of the species described by himself, in conjune- 
tion with the Rev. M. J. Berkeley, as V. tetratrupha, than I have, and 
therefore I am content to abide by his decision. (Fig. a ascus and 
sporidia, x 300.) 
11. MassaRra EBURNEA, Tul. Hypodermal, pulvinitumt or cfc, i 
depressed or subtruncate. Perithecia circinating, with loug necks. 
Asci large, obovate-cylindrical, obtuse, S-spored. — Sporidia elliptical or 
broadly ovate, quadrilocular, constricted at the joints, obtuse, smooth,
