on the Fungus which causes the Vine disease,” extracted from the “ Comptes 
rendus des Seances de l’Academie des Sciences, vol. xxxvii. This fungus, 
now well known under the name O'idium Tuckeri (Berk), consists of 
a network {Mycelium) of white, loose filaments, which covers here and 
there the green and healthy parts of the vine, and causes the formation of 
brownish or blackish spots. From these filaments, which are all superficial 
or external on the epidermis of the infested plant, spring thick tufts of 
simple pointed stalks, the ultimate points of each of which quickly becomes 
a large oval cell, as capable of propagating the fungus as any true seed 
could be. Independently of these reproductive bodies, the O'idium Tuckeri 
produces brown, generally pedicellate, fruits, coated with a cellular mem¬ 
brane, and containing very minute seeds, capable of germinating. These 
fruits are commonly larger than the swollen acrogenous bodies, described 
above, but not always so; they are of the same form, and are often borne 
on the same footstalk, almost appearing as if they were caused by a trans¬ 
formation of the normal seeds. From a close observation of these pecu¬ 
liar organs, M. Tulasne conjectures that the O'idium Tuckeri is of a very
