MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPH^RI^. 267 



Div. 4. CoNNATiE. 



42. S. (Htfoxylon) bubiginosa, Pers. ; Fr. S. M. ii. p. 340. Tab. XLV. fig. 43, ascus 

 with sporidia x 325. SporicUa uniseriate, dark brown, elliptical, but slightly ii-re- 

 gular, usually with one, sometimes with two or even three nuclei, 0-0004 inch long. 



43. S. (IIypoxylon) atro-purpurea, Tode ; Fr. S. M. ii. p. 340. Tab. XLV fie 44 

 sporidia X 325. Sporidia dark brown, paler when young, usually with two, some- 

 times one nucleus, 0'0004 to 0-0005 inch long. 



44. S. (Hypoxylon) perforata, Sz. ; Fr. S. M. ii. p. 340. Tab. XLV. fig. 45, sporidia, 



X 325. Sporidia I think uniseriate, like those of atro-purxmrea, but rather lighter- 

 coloured, 0-0004 inch long. The plant is easily known by the rusty-coloured peri- 

 thecia, and the white flat ostiola. 



45. SpHiERiA botryosa, Fr. S. M. ii. 342. Tab. XLVI. fig. 46, ascus with sporidia, X 225. 

 Asci variable in size, clavate, with the inner membrane very distinct, the latter filled 

 with innumerable multitudes of very minute granules ; granules colourless, about 

 0-0001 inch, endowed with Brownian motion. I should have doubted these granules 

 being true sporidia ; but I fijid the fruit of the plant in the Hookerian herbarium 

 coinciding exactly with that of authentic specimens from the Scleromycetes Sttecice. 

 Fries considers the plant a SphcBria with confluent perithecia, and not an Rypoxylon. 

 See ' Summa Veg. Scand.' p. 383, note 3. 



46. S. (Hypocrea) lateritia, Fr. S. M. ii. p. 338. Tab. XLVI. fig. 47, ascus with spo- 

 ridia, X 325. Sporidia uniseriate elliptico-acuminate, colourless, 0-0006 to 0-0007 

 inch long. I had some doubt whether the plants were ripe, and whether the sporidia 

 may not become bro^\Ti in age. The specimens in Hook. herb, are from Mr. Stephens's 

 herbarium. I have seen no other specimens of this species. 



47. S. (Hypoxylon) serpens, Pers. ; Fr. S. M. ii. p. 341. Tab. XLVI. fig. 48, ascus 

 with sporidia, x 325. Sporidia similar in colour to those of S. atro-purpurea, and 

 of about the same size. 



48. S. (Hypocrea) hyalina, Schwein. ; Fr. S. M. ii. p. 339. Tab. XLVI. fig. 49, ascus 

 with sporidia and free sporidia, X 325. Sporidia uniseriate, colouidess or greenish, 

 elliptico-acuminate but rather irregular, 0-0006 to 0-0008 inch long. 



49. S. (Hypoxylon) Sassafras, Sz. ; Fr. S. M. ii. p. 343. Tab. XLVI. fig. 50, ascus with 

 sporidia, X 325. Sporidia imiseriate, elliptical, clear brown, rather dark, 00004 inch 

 long. Very like S. atro-purpurea ; but the perithecia are of a rather darker colour, 

 and the ostiola obtuse or depressed, not mammillate. 



50. S. (Hypocrea) citrina, Pers. ; Fr. S. M. ii. p. 337. Tab. XLVI. fig. 51, ascus 

 with sporidia, X 325. Sporidia squarish, irregular in shape, colourless, normally 

 16 in an ascus. Hardly distinguishable in fructification from S. rit/a, &c., but easily 

 known by the yeUow colom", and effused condition of the stroma. It may be only a 

 peculiar condition of S. gelatinosa, Tode. 



51. S. (Hypocrea) lobata, Sz. Wormsk. ; Fr. S. M. ii. p. 343. Tab. XLVI. fig. 52, 

 ascus with sporidia, X 325. Not distinguishable in its fruit from the last, except 

 that the asci and sporidia (in the Kew specimens at least) are smaller.
