Transcaucasus. Sooty mould, Capnodium salicinum Mont., was

of Crimea; the following varieties being most resistant to the 
disease: Verdelho de Madeira, Sersial de Madeira, Pedro Xi- 
menes, Cabernet Sauvignon, Mourvede, Carignagne, Kokours,

VII. FOREST TREES. 
Pine. The one to four year old trees, especially, are often 
affected with falling of the leaves, due to the fungus Lopho- 
dermium pinastri Chev. The disease is essentially only a trouble 
of the nursery trees. It was most severe in the central part of 
Russia. One of the most dangerous fungi to the pine forests 
is Polyporus annosus Fr. as its spreads not only by means of 
its spores but also through the ground. In Russia it has been 
found as yet only in Lomzhin and Mogiley governments. Caeoma 
pinitorquum A. Br., the aecidial stage of Melampsora pini-tor- 
quuni, attacks the young trees and one year shoots of older trees, 
in many parts of Northern Russia. In 1903 it was also found in 
Kharkov government, in South Central Russia. Little injury 
results from the attacks of Coleosporium senecionis W. on the 
leaves. It was found in Smolensk and Tula governments. Caus¬ 
ing more serious injury is Peridermium pini forma corticola Lev. 
which was reported in 1903 from Tobolosk government in Si¬ 
beria. In seed beds in Perm government the seedlings just 
emerging from the ground were destroyed by Fusarium pini R. 
Hart., found in 1903 for the first time in Russia. 
Larch. In Smolensk government the larch was attacked 
by Caeoma lands W., the aecidial stage of Melampsora betulae 
on birch and M. tremulae on aspen. 
Birch. Melampsora betulina Wint. is very widely distributed 
in Russia, in 1903 being especially abundant in Smolensk and St. 
Petersburg governments; as well as in Tomsk and Tobolsk gov¬ 
ernments in Siberia. Polyporus betulinae Fr. is abundant, some¬ 
times attacking fifty per cent of the trees in the forest. In 1903 
it was reported from the Northwestern governments of Russia 
as well as from Askold Island, near Vladivostok. 
Oak. Injury by Daedalia quercina Pers. was reported from 
points in Caucasus and in Kovno government, while Hirneola 
cochleata Fr. was said to be injurious on Askold Island near 
Vladivostok. In. Kherson government, bordering on the Black 
Sea, seedlings were covered by the saprophytic slime mould 
Spinnaria alba DC. which caused some injury. 
Elm. In Simbirsk government and along the coast of the 
Black Sea in Caucasus the elm was attacked by Dothidiella ulmi 
Win.
