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



330. S. coRTicis, Sow. t. 372. f. 5 ; Tr. S. M. ii. 481 ; El. ii. 98. Tab. LIX. fig. 108, ascus 

 with sporidia and free sporidia, X 325. Sporidia biseriate or crowded, pale brown, 

 bvit of rather a rich colour, curved, variable in length, but in good ripe specimens 

 about O'OOOS inch long. Intermixed with the Spharia, and exactly resembling it, I 

 find other perithecia containing the bodies on the right of the figure, which were of 

 a darker broflTi, and 3-5- or 7-septate, varying from 0-0006 to 0-0012 inch long, 

 which I doubt not are perfect, free sporidia, the asci having deliquesced. 



331. S. TRANsvERSAiiis, Schw. ; Fr. El. ii. 94. Tab. LIX. fig. 109, ascus vrith sporidia, 

 X 325. Sporidia uniseriate, dark brown, elliptical, subglobose, or even quite globular, 

 0-0004 inch long. Arranged with the ObtiirattB, but belonging, I think, to the Denn- 

 datce, and in my opinion not distinct from S.pidceracea, Ehrh. Fries (El. ii. 94) con- 

 siders S. transversalis identical with S. myriocarpa. I have seen no specimens of the 

 latter Sphmria in fruit, but it is possibly not distinct from S. pulveracea. 



332. S. JuGLANDis, Fr. S. M. ii. 493. Tab. LIX. fig. 110, sporidia, x highly. Sporidia 

 biseriate, colourless, almond-shaped or narrowly elliptical, frequently curved, usually 

 4-nucleate, sometimes with the endochrome bipartite (? sometimes 5-partite), 0-0004 

 to 0-0005 inch long. I believe this to be the perfect form of S. Juglandis, Fr. The 

 Hookerian herbarium contains another form, next described, which is an authentic 

 specimen from the Scl. Suec, but which is not a true Sfhceria, and is perhaps an 

 imjierfect form of the species just described. 



333. S. JuGLANDis, Fr. S. M. ii. 493. Tab. LIX. fig. Ill, fruit, x highly. No asci; but 

 the perithecia contain a quantity of minute, colourless or slightly yellowish, narrowly 

 almond-shaped stylospores, borne on rather long pedicels, which, when broken off, 

 look lik e the fruit of a Cytispora, but are in reality only the fulcra of the stylospores. 

 Stylospores 0-0002 to 0-0003 inch long, sometimes with two nuclei or with a bipar- 

 tite endochrome. 



334. S. iNSPERSA, Sz. Tab. LIX. fig. 112, ascus with sporidia, X 325. Sporidia biseriate 

 or crowded, with the endochrome 4-partite, dark broT\'n, constricted at the partitions, 

 usually rather more pointed at one end than at the other, 0-0010 to 0-0011 inch 

 long. Not to be confounded with S. inspersa. Berk., which has very different 

 sporidia. 



335. S. (Sph^ropsis ?) uberiformis, Fr. S. M. ii. 491. Tab. LIX. fig. 113, fruit, x 325. 

 I could find no asci. Perithecia filled with elongate, acuminate, colourless spores, 

 having the endochrome 4-partite, 0-0005 to 0-0008 inch long. EasUy known by its 

 udder-shaped perithecia ; but it is, perhaps, not a true Sphceria. 



336. S. (Hendersonia ?) oppilata, Fr. S. M. ii. 493. Tab. LIX. fig. 114, fruit liighly 

 magnified. No asci. Perithecia filled with almond-shaped colourless spores with 

 bipartite endochrome, 0-0003 to 0*0004 inch long. This would be a Sphceria or a 

 Hendersonia, according to whether it has or has not asci. 



337. S. (Hendersonia) palina, Fr. S. M. ii. 494. The fruit of this plant is not distin- 

 guishable from that of S. oppilata, but the spores rarely exceed 0-0003 inch in length. 

 The endochrome also is sometimes continuous instead of bipartite, and the spores are 

 borne on long peduncles, as in S. Juglandis, but which I did not observe in S. oppilata.
