MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPH^ERI^. 285 



fruit of S. arundinacea. S. Junci is placed, in the ' Summa Veg. So.,' after Dothidea, 

 with the remark " Incerti generis, priori aflinis." 



200. SPHyEttiA ARUNDINACEA, Sow. Tab. XLIX. fig. 200, sporidia, X 325. Sporidia 

 hiseriate, yellowish-brown, linear, acuminate at one or both ends, 3-5-septate, 00010 

 to 00016 inch long. 



201. Sph^ria nebulosa, Pers. ; Fr. S. M. ii. p. 430. Tab. XLIX. fig. 201, ascus witli 

 sporidia, X 325. Sporidia hiseriate, coloiuiess, subacuminate, straight or slightly 

 cm-ved, uniseptatc, 0-0003 to 0*0005 inch long. 



202. Sph^kia Godini, Desm. Tab. XLIX. fig. 202, ascus with sporidia, x 325. Sporidia 

 hiseriate, linear-acuminate, uniseptate, colourless, 0-0010 to 0-0012 inch long. Messrs. 

 Berkeley and Broome state (Ann. Nat. Hist. s. 2. vol. \\\. p. 137) that this species 

 is identical with S. arundinacea, Sow. ; but in the Kew specimens the species differ 

 in the colour of the sporidia, and in the number of the septa. This, however, would 

 not prove them distinct, as the number of septa varies in many species, and sporidia 

 which are colourless when young frequently become brown in age. 



203. Sph^ria CLARA, n. s. Tab. XLIX. fig. 203, ascus with sporidia, x 325. Sporidia 

 hiseriate, colourless, subfusiform, 4-nucleate, sometimes also with some smaller 

 nuclei ; slightly constricted in the middle, 0-0010 to 0-0012 inch long. On some reed. 

 This fi'uit is described from a specimen which I had in my own herbarium, but 

 which I have mislaid. The species is not in the Hookerian herbarium. 



204. S. PARDALOTA, Mont. This plant produced only colourless, rather narrowly ellipti- 

 cal stylospores 0-0002 to 0-0004 inch long. The true sporidia are described as cym- 

 biform and biseptate. See Mont. Syll. p. 235. 



205. Sptt^RiA ? PANTHERiNA, Berk. The specimen of this plant produced no asci, but 

 fusiform stylospores 0-0008 to 0-001 inch long, and extremely narrow. 



206. Sph^eria longissima, Pers. Tliis species forms long dark spots studded with the 

 perithecia. The specimens at Kew are imperfect ; but in two of the perithecia I 

 observed elliptical or slightly curved bodies with two nuclei, and sometimes with a 

 septum in the middle, greenish or yellowish in colour, 0-0004 to 0-0006 inch long 

 and about half as wide ; but whether true fruit or not, I cannot say. I have seen no 

 other specimens.

 with a single large globose nucleus.
