276 MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPH^RI^. 



325. Sporidia biseriate or crowded, colourless, elliptic-acuminate; endocliroine 4- 

 partite, sometimes only 2-partite ; 0'0005 to O'OOOG inch long. 



124. S. (Vaxsa) cellulata, Fr. Syst. Myc. ii. p. 380. Tab. XLVII. fig. 120, sporidia, 

 X 450. Sporidia biseriate, very pale yellowish brown, simple, slightly cm'ved, rounded 

 at both ends, 0'0004 inch long. 



125. S. (Diploma ?) juglandicola, Schwein. ; Fr. S. M. ii. p. 385. Tab. XLVII. fig. 121, 

 fi'uit, X 325. Sporidia (? stylospores) uniseptate, dark brown, 0-0009 to 0.001 inch 

 long. To the naked eye the plant resembles S. pulvis-pyrius. 



Div. 10. Incuse. 



126. S. (Vaisa) angtjlata, Fr. S. M. ii. p. 390. Tab. XLVII. fig. 122, ascus with spori- 

 dia, and free sporidia, x 225. Sporidia imiseriate, very seldom biseriate, colourless 

 or pale sea-green, obtuse, constricted in the middle, furnished with 4 (? sometimes 5) 

 cUia, one proceeding from each pole and one from the middle of each side; endo- 

 clu'ome usually granular ; 0'0008 to 0-0012 inch long. The above is the usual form 

 of the sporidia ; but sometimes, when the endochrome is oleaginous and not granular, 

 the appearance of the sporidia is so different that they might almost be taken for a 

 second form of fruit. A second form of fruit does exist in this species, as to which I 

 would refer to my paper " On the Fructification of certain Sphajriaceous Fungi," 

 read before the Royal Society, in June 1857. See Phil. Ti-ans. 1857. 



127. S. (Valsa) melaspekma, Fr. S. M. ii. p. 389. Tab. XLVII. fig. 123, ascus with 

 sporidia, and free sporidia, x 325. Sporidia very numerous, slightly curved, of a 

 pale-yellowish tinge, 0-0002 to 0-0003 inch long. 



128. S. (Valsa) taleola, Fr. S. M. ii. p. 390. Tab. XLVII. fig. 124, ascus with sporidia, 

 and free sporidia, x 450. Sporidia biseriate, colourless or very pale green, elongate- 

 acuminate, frequently or usually sUghtly curved, 0-0007 to 0-0008 inch long. I think 

 there is no real septum. I find not the slightest difference between the sporidia of 

 Sphceria taleola and those of »S'. leiphcemia, and have little doubt that the two plants 

 are not distinct. I feel sure that the conceptaculum which is said to distinguish 

 S. taleola is a characteristic not to be relied upon ; for there are some species of 

 Sphceria which sometimes have a conceptaculum and sometimes not. The plants 

 marked S. taleola at Kew have no conceptaculum ; and I have seen other specimens 

 marked S. taleola also without a conceptaculiun. 



129. S. (Valsa) fulvo-pruinata, Berk. Tab. XLVII. fig. 125, asci with sporidia, x 325. 

 Sporidia uniseriate, sometimes slightly acuminate at each end, but sometimes obtuse 

 at the ends, slightly constricted in the middle, uniseptate, dark brown, paler at first 

 (and then an inner membrane and sometimes nuclei are visible), 0-0006 to 00007 inch 

 long. Easily recognized by the tawny colour of the protruded bark surrounding the 

 ostiola. 



130. S. (Valsa) nivea, Hoffm. ; Fr. S. M. ii. p. 386. Tab. XLVII. fig. 126, asci with 

 sporidia, and free sporidia, X 325. Asci crowded with sporidia ; sporidia colourless, 

 slightly curved, 0-0002 to 0-0003 inch long. 



131. S. (Valsa) foraminula, Pers. iaUtt. Tab. XLVII. fig. 127, ascus with sporidia, and
