almost equal propriety ; but the ostiola are somewhat elongated, and the perithecia 

 immersed in the matrix. Eventually, however, the bark is thrown off, and the peri- 

 thecia form rough, naked, scabrous masses. A dark line often surrounds the masses 

 of perithecia ; but the ai-ea it includes is very irregular, and tlie line itself not always 

 present. It might be taken for a coarse abnormal form of ,S'. stellulata ; but the spo- 

 ridia are more than double the size of those of S. stellulata, and of a different colour. 

 It is very common in this couiitry, principally on elm.

117. S. (Valsa) enteroleuca, Fr. S. M. ii. p. 381. Tab. XLVII. fig. 113, ascus with 

 sporidia, x 325. Sporidia biseriate, colom-less, oblong, acuminate at each end, con- 

 stricted in the middle, often slightly cm-ved, 4-nucleate, uniseptate (I think, but the 

 septum very difficult to make out), 0'0006 to 0-0007 inch long. On Bobinia Fseuda- 

 cacia. Perithecia very numerous in each pustule, deeply imbedded in a very white 

 stroma ; when cut across horizontally, a very well-defined black line is seen, which 

 arises from the wood surrounding the perithecia being blackened, thereby causing the 

 appearance of the existence of a conceptaculum ; but there is not really any. I have 

 received a plant from Mr. Bloxam marked as S. enteroleuca, Fr., of which fig. 114 



^ represents an ascus with sporidia x 325, and free sporidia more highly magnified. 

 The sporidia are very numerous, crowded, brownish yellow in the mass, almost colour- 

 less when single, ciu'ved, 0-0003 inch long. I suspect, from the habit of the latter 

 plant upon its fruit, that it is a form of Diatrype aspera. 



118. S. (Vaisa) anomia, Fr. S. M. ii. p. 381; El. ii. p. 77. Sporidia (spermatia?) 

 colourless, slightly curved, very minute, about 0'0002 inch long. A very doubtful 

 specimen ; but the fruit does not differ very materially from that figured in Sturm's 

 ' Deutschland's Flora.' 



119. S. (Vaisa) EXTENSA, Fr. S. M. ii. p. 381. Tab. XLVII. fig. 116, ascus with 

 sporidia, X 325. Sporidia uniseriate, colom-less, obtuse, slightly constricted in the 

 middle ; endochrome bipartite, smooth, and refractive, but doubtless sometimes 

 granular. 



120. S. (Valsa) detbusa, Fr. S. M. ii. p. 382. Tab. XLVII. fig. 117, ascus with spo- 

 ridia, X 325, and a free sporidium, X 450. Sporidia biseriate, colourless ; endochrome 

 divided into four, sometimes appai'ently into only two portions, elliptic, subobtuse or 

 subacuminate at the ends ; 0'0006 inch long. 



121. S. (Valsa) Pktjastri, Pers. ; Fr. S. M. ii. p. 380. Sporidia biseriate, almost 

 coloiu'less, but brownish yellow in the mass ; minute, curved, O'OOOS inch long. 

 Hardly distinguishable from the fruit of Diatrype stigma. 



122. S. (Valsa) Carpini, Pers. ; Fr. S. M. ii. p. 384. Tab. XLVII. fig. 118, sporidia, 

 X 325. Sporidia curved, colourless, highly refractive, 0-0006 to 0-0008 inch long. 



Thei'e is another specimen in the Herbarium, marked Sp)h. Carpini; but as the 

 sporidia are just like those of Sph. syngenesia, it jirobably belongs to the latter 

 species.
