ON FUNGOID DISEASES OF THE VINE.

This species was described by Messrs. Berkeley and Broome in the 
“ Annals of Natural History” (under no. 748) in the following 
manner:—“ Forming little brownish specks on either side of the 
leaf, consisting of a few subconglomerate perithecia. Spores oblong, 
clavate, *002 inch (or *05 mm.) long, endochrome, sometimes re¬ 
tracted to one end, containing a few minute granules very rarely 
there are one or two septa.” The typical specimens unfortunately 
did not bear out this description, but it must be borne in mind that 
we were not at liberty to do more than examine a minute fragment 
of a borrowed specimen. Whether there are other perithecia to 
be found containing the large spores described by Messrs. Berkeley 
and Broome, it is impossible to affirm or deny; all that we discovered 
was a great profusion of very minute, almost linear, spores, exactly 
like those of the specimens in “ Fungi Britannici,” no. 206, not 
more than *006 mm. long, whereas those figured in the “ Annals ” 
were stated to be nearly ten times as long. It is impossible to 
explain this contradiction, except on the hypothesis that there are 
perithecia mixed with, and undistinguishable from, the rest con¬ 
taining different fruit. In our own specimens collected at Shere 
and at Highgate, we were never able to find any other than the 
minute spores which occurred in profusion also in the typical 
specimens. Neither form of spores belong to Septoria as now 
limited. Those which we have found, and to which our published 
specimens belong, would now be called Phyllosticta Badhami , C., 
whereas the description in the “ Annals,” but not the specimen, as 
far as we could discover, belongs to the genus Ascochyta. Accepting 
the limits of these genera as defined by Professor Saccardo in this 
investigation, we examined the specimens published by Hr. Baben- 
horst (no. 852), under the name of Septoria Badhami var. Fraxini , 
on ash leaves, and we were surprised to find it was not a Septoria at 
all, but a species of mould ( Dematiei ) in dense tufts, without any 
kind of a perithecium, and closely resembling Passalora lacilligera , 
Mont., with long, lanceolate, uniseptate spores, one cell much 
broader than the other. 
Septoria falx , Berk. & Curt. There is still another species of 
Septoria on Yine found in North America, but in this instance in¬ 
habiting the twigs, to which the above name is given. It is de¬ 
scribed in “Grevillea” (vol. iff., p. 11) as consisting of rather large 
erumpent perithecia, containing filiform spores, seated on pedicels of 
equal length and resembling when in situ a reaping-hook. This 
is a species which has never come under our notice.
