considerably exceed this. The length of the ascus figured in Pl. XXV. fig. 16 (a) is as 
much as th of an inch. 
.. Sollman is, I think, in error in placing it in the division Pertuse. Although of some- 
what irregular growth, its characters are almost those of a Valsa. If it were retained in 
the genus Spheria, its proper place would be with the Endoxyle. 
Plate XXV. fig. 16 (a) represents an ascus with the tips of the sporidia escaped from 
the ruptured end, x 220; (b) represents the perithecia in situ, x 2 diameters; (c) the 
ostiolum and dark circle, seen from above, slightly magnified; (d) a detached perithecium, 
magnified. 
NECTRIA HIRTA, Dlox., n. s. 
Perithecia minute, subglobose, with a slightly prominent ostiolum, of a pinkish salmon- 
colour, covered with prominent white hairs. Sporidia biseriate, curved, colourless, tapering 
slightly at each end, multiseptate, attaining 0-003 inch in length. On decaying rails, 
Twycross, Leicestershire. The Rev. A. Bloxam. A small but beautiful species, remark- 
able for its hairy perithecia and the great size of its sporidia, which differ entirely from 
the ordinary form. of fruit in Nectria.

SPHJERIA FRAXINICOLA, n. s. (Hndophlee.) 
Perithecia sublageniform, with a pointed or nipple-like ostiolum, having the base 
sometimes adnate to the wood, and leaving a circular depression in the wood when 
detached ; piercing through the inner bark and just through the outer bark. Sporidia 
elliptical, 00005 to 0:0006 inch long, uniseriate, biseptate, trinucleate, colourless, the 
outer membrane and septa sometimes invisible, in which case the sporidia appear com- 
posed of three detached endochromes, as at (a) Pl. XXV.fig. 34. The ostiola of the 
perithecia fall off with a circumscissile fissure as in the division Pertusee. Sometimes 
the perithecia may be stripped off with a fragment of the inner bark, showing an approach 
to the Obtectze. 
On dead ash-branches, intermixed with Hysterium Fraxini and with some Valsa of 
the division Cireumscriptee. Combe Place, near Lewes, September 1862.

SPRJERIA VERECUNDA, n. s. (Endophlee.) 
Perithecia subglobose or conical, very small, with a pointed or nipple-shaped ostiolum 
which just penetrates the outer bark. Sporidia eight, pale brown, with five (rarely six) 
transverse septa and from one to three longitudinal septa, constricted at each septum, 
mostly uniseriate and overlapping, occasionally biseriate, 0-0008 to 0:0010 inch long. 
Batheaston, October 19th, 1861.

SPHARIA TRIGLOCHINICOLA, n. s. (Caulicole.) 
Perithecia minute, subglobose, situated beneath the epidermis, which is pierced by the 
papillate ostiolum. Sporidia biseriate, triseptate, oblong in a front view, curved in a side
