MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPH^RliE. 325 



310. S. coNFOBMis, B. and Br. Ann. and Mag. Nat. Hist. ser. 2. vol. ix. p. 325. pi. 11. fig. 19. 

 Tab. LVIII. fig. 88, ascus with sporidia, x 220. Sporidia biseriate, elliptical, often 

 slightly ctirved, colom-lcss, pellucid, endochronic 1-partite, O'OOOT to 0'0008 inch 

 long. There arc not, I think, any real septa. 



311. S. (Haxonia) ditopa, Fr. S. M. ii. 381. Txb. LVIII. fig. 89, asci with sporidia and free 

 sporidia, X 460. Sporidia crowded, very numerous, coloui-less, oblong, narrow, rounded 

 or somewhat pointed at the ends, O'OOOG 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. pi. 10. fig. 15*. Messrs. Berkeley and 

 Broome, however {I. c), mention Dr. Roussel's specimens of .S*. ditopa as having uni- 

 septate sporidia. 



312. S. QTJADRi-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 sporidiuni with four nuclei, O'OOOG 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. jndcis-pyrius, Weybridge, 

 Surrey, September 7th, 1856. 



313. S. Rtjbi, n. s. Tab. LVIII. fig. 91, (a) asci with sporidia not quite ripe, X 325 ; 

 (i) ripe sporidia, X 4.50. Sporidia biseriate, colourless, each with foui- 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, punctiform, 

 just penetrating the bark with theu- minute ostiola. On bramble, Weybridge, 

 Surrey, September 12th, 1856. 



314. S. INQUILINA, Wallr. ; Fr. El. ii. p. 100. Tab. LVIII. fig. 92, sporidia highly mag- 

 nified. Sporidia biseriate, colourless, subfusiform, constricted in the middle, 4-nu- 

 cleate, 00004 to 0'0005 inch long. On dead stems of Smyrnium Olusatrum. Mailing, 

 near Lewes, August 24th, 1858. I have no doubt about the species, although the 

 contents of the perithecia in these specimens is not black, but colouidess. VS'hen 

 examined under a lens, without extracting the contents, they appear black ; but if 

 picked out on the point of a needle, they will be found to be coloui-less. 



315. S. ACTJS, Blox. MS., n. s. Tab. LVIII. fig. 93, sporidia highly magnified. Sporidia 

 biseriate or crowded, colourless, narrowly eylindi-ical, with rounded ends, or acu- 

 minate at the ends and then almond-shaped, 0-0003 to 0-0004 inch long, endochrome 

 2-4-partite. Perithecia small, subglobose, flattened, concealed by the epidermis, 

 which is pierced by the sharp-j^ointed minute ostiola.

pi. 11. fig. 33. Tab. LVIII. fig. 94, ascus with sporidia highly magnified. Sporidia 



uniseriate, elliptical, colourless, 00003 to 0-0004 inch long, with a nucleus at each 



extremity, as in the spores of the genus Fhoma.
