species, so named on the faith of specimens from the late Dr. 
Curtis and from Mr. Bavenel, hut we have failed to meet with 
any description. It forms brown spots on the leaves of Vitis vinifera , 
and perhaps of other species, on which the small brown perithecia 
are scattered ; but the spores are globose with a reticulated surface, 
about *01 mm. diameter. This, then, is clearly not a species of 
Septoria or Phyllosticta , but belongs to the genus Sacidium, and 
will henceforth have to be known by its more accurate name of 
Sacidium viticolum. Specimens have been issued in Bavenei’s 
“ Pungi Americani ” (no. 26) under the old name of Septoria viticola. 
Septoria ampelina , Berk. & Curt. This is a true Septoria on 
the leaves of V vulpina , and perhaps may be partly the S. vitis of 
Curtis’s catalogue. It is described in “ Grevillea ” (under no. 440) 
by the Bev. M. J. Berkeley, and consists of brownish or pale rufous 
spots, in which the small and indistinct perithecia are immersed. 
The spores are thread-like, straight or curved, mostly containing 
several nuclei in a row, and measure from *04 to - 05 mm. in length. 
This species is also issued in Bavenel’s “Pungi Americani” (no. 
29) from South Carolina. 
Septoria vitis , Lev. Is a species described in the “Annales des 
Sciences Baturelles ” for 1846, vol. v., p. 279. The perithecia 
are very minute, gregarious in blackish spots. It occurs on leaves 
of V. vinifera in the neighbourhood of Paris. By favour of the 
Bev. M. J. Berkeley we have seen an original specimen, the ex¬ 
ternal appearance of which is certainly very distinct. The peri¬ 
thecia are closely packed together on the spots, which are thereby 
quite blackened. Species of Septoria after dessication are most 
unsatisfactory things to examine, and this is no exception; but as 
far as we could ascertain from the examination of a single cluster of 
perithecia the spores are narrowly oblong, and less than *01 mm. 
in length. Leveille describes them as curved and fusiform, with¬ 
out septa, but he gives no dimensions. According to the limitation of 
genera above alluded to this cannot now be retained in Septoria 
on account of the spores. It will therefore be relegated to Pliyllos- 
ticta , with the name of P. leveillei, C., there being already a 
P. vitis , from which this is undoubtedly distinct. 
Septoria Badhami , B. & Br. Being in some doubt whether we had 
accurately determined this species, of which specimens were dis¬ 
tributed in “ Pungi Britannici ” (series i., no. 206), the Bev. M. 
I. Berkeley was again appealed to, and from his authentic speci¬ 
men the accuracy of our published specimens has been established.
