6. SPHJERELLA PUNCTOIDEA, n. sp. Epiphylla. Peritheciis atris, 
nitidis, innato-prominulis, in maculas minores collectis, demum col- 
lapsis e concavis. Ascis cylindricis, curvatis vel flexuosis. Sporidiis 
uniseriatis; ellipticis 1. subeymbiformibus, hyalinis.—Perithecia black, 
shining, semi-innate, prominent, disposed in little groups of seven or 
eight on the upper surface of leaves, collapsed and concave when dry. 
Asci cylindrical, curved or flexuose. Sporidia uniseriate, elliptical or 
subcymbiform. Hyaline, highly refractive and colourless, Length of 
asci 056 mm. (-0021 in.), of sporidia 0125 mm. (00045 in.).—On 
the upper surface of Oak leaves. Shere, Surrey (Dr. E. Capron). Jed- 
burgh (Mr. Jerdon).—Quite distinct from S. punctiformis, with which 
it has probably been confounded : the asci are cylindrical, the sporidia 
are longer, and the perithecia are different in habit and disposition, 
always occurring in small groups and on the upper surface only. 
S. maculeformis often occurs on the under surface of the same leaf.

SPHJERELLA MYRIADEA. Epiphyllous. Perithecia very minute, 
numerous, black, aggregated in large unequal cinereous patches. Asci 
subfusiform. Sporidia biseriate, elongated, triseptate, pointed at eath 
extremity, ‘035 mm. (0013 in.) long.—Spheria myriadea, DC. FI.

8. SPHARELLA MILLEGRANA, #. Sp. Epiphylla. Peritheciis mi- 
nutis, sparsis, numerosis, innatis, globosis, atris. Ascis brevibus, cylin- - 
dricis. Sporidiis linearibus, uniseptatis, cellula supra incrassata, hya- 
Perithecia scattered, numerous and minute, 
somewhat resembling those of S. myriadea, but not so closely aggre- 
gated, and not collected in definite patches. Asci short, cylindrical. 
Sporidia crowded, linear, and uniseptate, the upper cell being ventri- 
cose, :015 mm. (-0006 in.) long. (Pl. L- Fig. 15.)—On the upper 
linis. —Epiphyllous.
