CXXXiv PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 
hitherto I have been unable to find the Uromyces upon it, although 
it is a British species." 
Flics attacked by a Fungus. — With reference to the specimens 
brought before the last meeting, it is reported from an examina- 
tion made at Kew that "the fungus is Empus conglomerata, 
Thaxtcr (a somewhat rare species), parasitic on Diptera, espe- 
cially on the larvae and imagines of TipulfE. Distrib. — Europe 
and United States. This is the first record for Britain." 
Grapes diseased. — With reference to the samples sent to 
a recent meeting, the following report has been received from 
Kew : — " The Vines are attacked by a fungus called Gloeo- 
sporium ampelophagum, Sacc, a well-known pest in vineyards, 
The mycelium of the fungus is perennial in the branches, 
and passes into the new shoots as they are developed. The 
first fruits formed by the fungus in the spring are found on 
the old wood, and the spores carried by the wind or rain or 
syringing reach the flowers and young fruit ; the mycelium also 
travels along the tissues of the branches into the inflorescence. 
A mixture of equal parts of sulphur and powdered chalk should 
be applied to every part of the Vine, dating from the commence- 
ment of branch formation until the fruit is set. All shoots that 
are more or less covered with minute black specks should be cut 
away and burnt at once, as these are the fructification of the 
fungus." 
Thornless Gooseberry. — MM. Letellier et Fils forwarded from 
Caen some growing plants of this variety, of which they have 
sent out four kinds, raised by M. Ed. Lefcrt, of Meaux, France. 
The usual triple spines were either quite absent or represented 
by mere rudiments only. 
Potatos (jroivn in Jadoo Fibre. — Jadoo fibre appears to 
be peat moss saturated with chemicals. The Potatos were very 
clear, clean, and apparently thin-skinned, but small. The com- 
mittee could pass no opinion upon their value, as no information 
was received as to the composition of the material in which they 
were grown. 
Sroeet Williams, Sudden Jleversion of.— Mv. Caimell sent 
some trusses, witli small jagged-edged petals of a crimson colour, 
which had appeared among his long-selected beds of Sweet 
WilliaiiiH, the margins of the petals being rounded and smooth. 
The form whicli, on its appearance, is never allowed to set seed,
