MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRLÆ. 277 
free sporidia, x 325. Sporidia biseriate, elliptical, sometimes acuminate, sometimes 
obtuse at the ends, colourless, 0:0011 to 00016 inch long. In some sporidia the 
, endochrome was broken up into two, three, or six portions, but, I think, only from 
being dry. 
132. S. (VALSA) PROFUSA, Fr. S. M. ii. p. 392. Ta». XLVII. fig. 128, sporidia, x 450: 
a, à young sporidium almost colourless or very slightly greenish; 5, a sporidium 
more advanced; c, a ripe sporidium. The sporidia when young have a gelatinous 
envelope, which disappears in age, the asci frequently containing only four sporidia 
arranged in one continuous series; I believe, however, the normal number to be 
eight, and that they are sometimes arranged biseriately. "The asci are absorbed at a 
very early period, so that usually only free sporidia are to be found. "These when 
ripe are of a clear rich olive-brown colour with a very slight greenish tinge, oblong- 
elliptic, 0:001 to 0:002 inch long. One of the most beautiful Sphæriæ in point of 
. fructification. 
133. S. (DIPLODIA ?) RUDIS, Fr. El. ii. p. 98. Tas. XLVII. fig. 129, fruit, x 325. No 
asei; sporidia (?stylospores) rather dark brown, broadly elliptical, but slightly con- 
stricted in the middle, 0:0010 to 0:0011 inch long. 
134. S. (VALSA) MICROSTOMA, Pers.; Fr. S. M. ii. p. 388. Ta». XLVIL fig. 130, ascus

curved, obtuse at the ends, 0:0005 to 0:0007 inch long. 
185. S. (VALSA) DISSEPTA, Fr. S. M. ii. p.392. Tas. XLVIII. fig. 131, asci with sporidia, 
and free sporidia, x 325. Sporidia biseriate, colourless, linear-acuminate or almond- 
shaped; endochrome bi- or quadripartite; 0*0004 to 00005 inch long.

fig. 132, sporidia, x 325. Sporidia biseriate, colourless, linear, pointed at the ends ; 
endochrome bipartite, sometimes quadripartite ; 0:0006 inch long. This agrees with 
Montagne's description, except that he calls the sporidia obtuse. =

colourless when single, curved, 0:0004 inch long. Described from a specimen of
