2009.08.08: Austria, Vienna XXII. district, 155 m AMSL, growing on badly damaged Populus sp.(near creek -
Hausgraben).Of course mistletoe isn't the main or primary reason for trees dying but they help the process along. My guess would be that this poplar won't last very long, probably a couple of years.The tree could be either Populus nigra or one of its hybrids, P. canescens and - as suggested below by Sciadopitys - P. canadensis, especially as it
is true that the hybrid P. canadensis is particularly often host of Viscum - however, I've also seen plenty of P. nigra bearing V. album.Both species are common.German name: Laubholz-Mistel.
