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



to Cryptogamic Botany,' p. 281, Mr. Berkeley figures the sporidia of S. pulvis-pyrms 

 with as many as five septa, and of a more elongated form than in my figure. In all 

 the specimens (and they are very numerous) which I have examined, I have never 

 found more than three septa, nor have I ever seen the sporidia so elongated as in 

 Mr. Bei'keley's figure. Mr. Berkeley himself mentions the sporidia as being trisep- 

 tate in ' Ann. and Mag. of Nat. Hist.' ser. 2. vol. vii. p. 189. 



249. 8. CONGLOBATA, Fr. S. M. ii. p. 414. Tab. LVII. fig. 33, ascus with sporidia, and free 

 sporidia, x 325. The specimens of this Spharia in Hook. herb, show clearly that 

 this species is only a crowded, subcuticular, eriimpent form of S.pulms-pyrius. Some 

 of the perithecia are bursting transversely, some longitudinally, and others form 

 csespitose masses ; others again have the ordinary scattered habit of S. pulvis-pyrius. 

 They form a very instructive series of specimens. 



250. S. DioiCA, Fr. S. M. The specimens of this plant in Hook. herb, show clearly that 

 (Uke S. conglobata) this species is only a subcuticular form of ^S*. pidvis-pyrms. 



251. S. MOROiBES. n. s. Tab. LVII. fig. 84, ascus with sporidia, and free sporidia, x 325. 

 Sporidia biseriate, greenish brown at first, eventually brown, subhyaUne, elliptical, 

 0-0004 to 0-0005 inch long. Perithecia rugose, small, like very small specimens of 

 S. moriformis, from which species the present differs altogether in the nature of its 

 sporidia. 



252. S. PLATEATA, Pers. in litt. Tab. LVII. fig. 35, ascus with sporidia, X 325. Sporidia 

 crowded, yellowish brown, multipartite, subelliptical, 0-0008 to 0-0010 inch long. 

 On wood. Very like S. pulvis-pyrius, except in the sporidia — possibly only a small 

 form of S. Sparta, Nees, which latter does not differ essentially from S. elongata, Fr. 



253. S. SPERMOIDES, Hofim. ; Fr. S. M. ii. p. 457. Tab. LVII. fig. 36, ascus with sporidia, 

 and free sporidia, x 325. Sporidia biseriate, coloui'less, curved, endochrome some- 

 times bipartite, 0-0008 inch long. 



254. S. MAMM^FORMis, Pcrs. ; Fr. S. M. ii. p. 455. Tab. LVII. fig. 37, sporidia, x 450. 

 Sporidia dark clear broAvn, subcymbiform, varying much in size, from 0-0008 to 

 0-0016 inch long. 



255. S. STERCOBARiA, Sow. ; Fr. S. M. ii. p. 455. Tab. LVII. fig. 38, ascus with sporidia, 

 X 220. Sporidia uniseriate, brown, eventually quite opaque, at first colourless, ellip- 

 tical, or almond-shaped, 0-0016 to 0-002 inch long. 



256. S. STERCORARIA, Sow. var. ? I subjoin here a description of a Sphceria which. I have 

 found growing on horse-dung, and which is probably the same species as the last, 

 notwithstanding its smaller sporidia and curious ostiola. Perithecia solitary, or few 

 together ; ostiola formed of a number of processes arranged in a penicillate manner, 

 each consisting of a single row of irregularly-shaped cells, the upjjer cell being 

 pointed. Sporidia mostly uniseriate, but sometimes biseriate, greenish at first, then 

 darker, probably eventually black, elliptical, 0-0010 inch long. Tab. LVII. fig. 39 («) 

 represents an ostiolum broken off, X 325 diameters, and fig. 39 {b), an ascus with 

 sporidia similarly magnified. 



257. S. STERCOBARIA, Fr. S. M. ii. p. 455 ; S. stercoris. El. ii. p. 104. Tab. LVII. fig 40, 

 sporidia, x 325. SporicUa biseriate, dark opaque rich brown, consisting of four
