293. S. VIBRATILIS, Fr. S. M. ii. 482. Authentic specimens of this Sphæria exist in the 
Hookerian herbarium, but the fruit is not ripe. As far as I could make out, the 
sporidia appear to differ very little from those of S. stellulata. There is another 
Sphæria in the collection marked by Mr. Berkeley “ 8. vibratitis, Fr.” in which the 
fruit is very different. Ta». LVIIL fig. 74, represents the fruit of the latter plant, 
X 325, of which the following is a description :—Sporidia uniseriate or overlapping, 
pale brown, oblong-elliptic, but slightly curved, endochrome bipartite, 0°0005 to 
0:0006 inch long.

295. S. (HALONIA) CUBICULARIS *, Fr. S. M. ii. 477; El. ii. 97. Ta». LVIIL fig. 76, 
sporidia, x 325. Sporidia uniseriate, dark brown, elliptieal, often acuminate at the 
ends, 0-0006 to 0:0007 inch long. Easily known by the ostiola being surrounded by 
a white tubercle formed from the wood. The sporidia, when free, are often surrounded 
by a narrow border. I have a specimen from Dr. Montagne in which the sporidia 
reach 00010 inch in length. It will be observed that the sporidia differ entirely 
from the generic characteristies given by Fries. LE ee 
296. S. LrvmDA, Fr. S. M. ii. 479. Tas. LVIIL fig. 77, sporidia, x 825. Sporidia uni- 
seriate, brown or yellowish-brown, normally I think triseptate, but frequently with 
longitudinal partial septa, and sometimes (from the breaking up of the endochrome) 
having a cellular appearance, elliptical, 0-0005 to 0:0007 inch se Ne 
297. S. (SPHÆROPSIS) PRUINOSA, Fr. S. M. ii. 486. Not ascigerous, the A 7 
dueing only a quantity of minute eurved spermatia, colourless ve eas d 
brown in the mass. There are two specimens in the herbarium, one from 
Suec. without fruit, and the other containing the spermatia, just mentioned.
