316 MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPH^RI^. 



to 0*0026 inch long. I suspect that the sporidia of S. hirsuia, and perhaps also those 

 of Spharia ovina and Sphceria canescens, are multiseptate when perfect. 



231. S. OVINA, Pers. ; Fr. S. M. ii. p. 446. Fructification not distinct from that of S. hir- 

 suta {post). I have found, however, on one or two occasions specimens which I be- 

 lieve to he S. oviiia, in which the sporidia exhibit under the microscope a peciiliar 

 pink tinge, each sporidium being also furnished with a clear, round, colourless spot. 

 Tab. LVII. fig. 16, represents the fruit of tliis form X 325 diams. 



282. S. c^siA, Carm. Tab. LVII. fig. 17, ascus with sporidia highly magnified. Sporidia 

 (? always) uniseriate, colourless, elliptical, or subpyi-iform, about 0'0002 inch long. 

 Perithecia white, very hairy. This specimen is marked "S. ovina statu juniori;" but 

 whoever so named it, had clearly not compared the fruit of the two species. 



233. S. HiRSUTA, Fr. S. M. ii. p. 449. Tab. LVII. fig. 18, ascus with sporidia, x 220. 

 Sporidia biseriate or crowded, pale brown, long, flexuous, 0"002 to 0-0026 inch long. 

 See remarks under S. HacocUum {supra). 



234. S. EHODOCHLORA, Mont. Syll. p. 227. Tab. LVII. fig. 19, ascus with sporidia, x 325. 

 Sporidia crowded, colourless, broadly elliptical, with a reticulated appearance, but 

 whether from the spores being multicellular, or from a number of nuclei touching 

 one another, I cannot say ; 0-0005 to 0-0007 inch long. 



235. S. MTJTABiLis, Sz. Tab. LVII. fig. 20, ascus with sporidia, x 325. Sporidia bise- 

 riate, colourless, ctirved, acuminate, endochrome 4-partite, 0-0008 inch long. Very 

 like S. ptdvis-pyriiis to the naked eye, but under a power of 50 diams. the perithecia 

 exhibit a very slight brownish hairiness, principally at the base. 



236. S. PiLOSA, Pers. ; Fr. S. M. ii. p. 440. Tab. LVII. fig. 21, ascus with sporidia, x 

 about 325. Sporidia uniseriate, colourless, elliptical, uniseptate, or with the endo- 

 chrome bipartite, 0-0003 to 0-0004 inch long. A small Sphceria, like B. pulvis- 

 pyrkis, but decidedly hairy. 



237. S. (Ceratostoma*) chionea, Fr. S. M. ii. p. 446 ; El. ii. p. 92. Tab. LVII. fig. 22, 

 sporidia, X 325. Sporidia elliptical or subglobose, dark brown, 0-0003 to 0-0005 inch 

 long. 



238. S. STRIGOSA, A. and S. ; Fr. S. M. ii. p. 448. In my opinion not distinguishable 

 from S. canescens, Pers. Fries says, " A praecedente " (that is S. canescens) " non 

 facile dignoscitur." 



239. S. Brassic^, K1. ; Eng. Fl. p. 261. Tab. LVII. fig. 23, ascus with sporidia, x 220. 

 Sporidia uniseriate, at first colourless, then pale brown, ultimately dark opaque 

 brown, elliptical, with pointed ends, or lozenge-shaped, 0-0014 to 0-002 inch long. 

 On Brassica oleracea. Perithecia large, hairy at the bottom, hairs white or brown ; 

 sporidia sometimes with two large nuclei, sometimes with a dark line not extending 

 quite across the sporidium. 



240. S. PULViNULTis, Berk. Tab. LVII. fig. 24, sporidia, x 325. Sporidia iri-egular in 

 shape, multiseptate, ? multicellular, very dark brown, varying much in size, from 



* Ceratostoma, Fr. Obs. Perithecium membranaceous, soft ; ostiolum subulato-rostrate, with a penicillate ape.x. 

 Nucleus gelatinous, asci soon dissolving (in some species not yet discoTered) ; spores simple, erumpent, surrounding 

 the apex of the perithecium.
