Diseased leaves are much larger than the normal, but are neither thickened nor blistered; on the under side they have a whitish or reddish coating, and fall off easily. I have never observed the disease on the stems of bilberry. In spite of these external differences, it is believed that the host-plants are in both cases attacked by the same species of Rrohasidium, but I do not know of any observations on the reciprocal infection of the two t.— rhodoJcndri on Rhododend. (v. Tubeuf phot.) A disease due to an Uxohasidium is by no means uncommon on Vaccinium uliginosum (bog whortleberry).- Shoots of diseased plants are deformed, while their leaves become more or less thickened and assume a beautiful rosy colour. On Vaccininm Oxycoccos (true cranberry) the shoots and leaflets also become thickened and rose-coloured. Rostrup dis- tinguishes this as a separate species {Ewhasidinm oxycocci). Ex. andromedae Peck, produces on Andromeda iiolifolin. symptoms similar to those just described for the preceding species. (IJritain and America.) ^ Saclebeck [Botan. Centralb/att, 1S86) records it in huge <|ii;uitity near Harburg. This is the host-species given by Massee (British Funijus-F/ora, 1892). -Tubeuf, " ; Pflanzenkrankheifev, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Tubeuf, Karl, freiherr von, 1862-; Smith, William G.
