Tas. LVIII. fig. 88, ascus with sporidia, x 220. Sporidia biseriate, elliptical, often 
slightly curved, colourless, pellucid, endochrome 4-partite, 00007 to 0:0008 inch 
long. There are not, I think, any real septa. 
311. S. (HaLoNtA) DITOPA, Fr. S. M. ii. 381. Tas. LVIII. fig. 89, asci with sporidia and free 
sporidia, x 450. Sporidia crowded, very numerous, colourless, oblong, narrow, rounded 
or somewhat pointed at the ends, 0:0006 to 0:0007 inch long. Fries, in the * Summa 
Veg. Scand.,’ describes the sporidia as septate. It is possible they may sometimes 
be so, but I have never seen them otherwise than continuous, with a nucleate or 
granular endochrome. They are figured so, moreover, by Messrs. Berkeley and 
Broome, in Ann. and Mag. N. H. ser. 2. vol. ix. pl. 10. fig. 15*. Messrs. Berkeley and 
Broome, however (1. c.), mention Dr. Roussel's specimens of S. ditopa as having uni- 
septate sporidia. | ; 
312. S. QUADRI-NUCLEATA, n.s. TAB. LVIII. fig. 90, sporidia, x 450. Sporidia biseriate, 
very closely packed, colourless, narrowly oblong, pointed or rounded at the ends, 
each sporidium with four nuclei, 0-0006 inch long. Perithecia small, subglobose, with 
a mammillate ostiolum, which pierces the outer bark, making a circular hole or a 
rimose transverse fissure in the bark. On a stick with S. pulvis-pyrius, Weybridge. 
Surrey, September 7th, 1856. 
313. S. RUBI, n.s. Tas. LVIII. fig. 91, (a) asci with sporidia not quite ripe, X 325; 
(5) ripe sporidia, x 450. Sporidia biseriate, colourless, each with four large nuclei, 
subfusiform, but wide in the centre, with the sides flexuous, and mostly elongated 
at each end into a hyaline mucronate appendage. Perithecia very small, posco, 
just penetrating the bark with their minute ostiola. On bramble, Weybridge,

cleate, 0-0004 to 0-0005 inch long. On dead stems of Smyrnium Olusatrum. vg 
near Lewes, August 24th, 1858. I have no doubt about the species, eam 
contents of the perithecia in these specimens is not black, but colourless. Å té 
examined under a lens, without extracting the contents, they sii black; but ı 
picked out on the point of a needle, they will be found to be colour: d AR
