MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRLÆ. 267 
Div. 4. CoxNATX. 
42. S. (HYPOXYLON) RUBIGINOSA, Pers.; Fr. S. M. ii. p. 340. Ta». XLV. fig. 43, ascus 
with sporidia x 325. Sporidia uniseriate, dark brown, elliptical, but slightly irre- 
gular, usually with one, sometimes with two or even three nuclei, 0:0004 inch long. 
43. S. (HYPOXYLON) ATRO-PURPUREA, Tode; Fr. S. M. ii. p. 340. Tan. XLV. fig. 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. TA». XLV. fig. 45, sporidia, 
. X 325. Sporidia I think uniseriate, like those of atro-purpurea, 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. SPHÆRIA BOTRYOSA, Fr. S. M. ii. 342. Tas. 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 find the fruit of the plant in the Hookerian herbarium 
coinciding exactly with that of authentic specimens from the Scleromycetes Sueciæ. 
Fries considers the plant a Sphæria with confluent perithecia, and not an Hypoxylon. 
See ‘Summa Veg. Scand.’ p. 383, note 3. : 
46. S. (HYPOCREA) LATERITIA, Fr. S. M. ii. p. 338. Tas. XLVI. fig. 47, ascus with spo- 
ridia, x 325. Sporidia uniseriate elliptico-acuminate, colourless, 00006 to 0:0007 
inch long. I had some doubt whether the plants were ripe, and whether the sporidia 
may not become brown 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. 841. Tas. 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. 8. (Hyrocrea) HYALINA, Schwein.; Fr. S. M. ii. p. 339. Tas. XLVI. fig. 49, ascus 
with sporidia and free sporidia, X 325. Sporidia uniseriate, colourless or greenish, 
elliptico-acuminate but rather irregular, 0:0006 to 00008 inch long. 
49. S. (HyroxynLon) SASSAFRAS, Sz. ; Fr. S. M.ii.p.343. Tam. XLV I. fig. 50, ascus wäh. À 
sporidia, x 325. Sporidia uniseriate, elliptical, ent dark, 0-0004 : 
long. Very like S. atro-purpurea ; but the aperi are of. a m darker colour, 
and the ostiola obtuse or depressed, not mammillate. 2 
50. S. (Hyrocrea) cITrINA, Pers.; Fr. S. M. ii. p. 337. Tas. ass = 51, ET 
with sporidia, x°S25: --Bporidia “squarisb; irregulat in shape, colour es, Norma y 
16 in an ascus. Hardly distinguishable in fruchfoneun from S. rufa, &c., = € 
known by the yellow colour, and effused condition of the stroma. It may be only a 
peculiar condition of S. gelatinosa, Tode. 
51. S. (HyPOCREA) LOBATA, SZ. Wormsk.; Fr. 8. M. ii. P- 348. Tap. XLVI. fig. 52, 
nåde 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. :
