During some relatively strong winds a few months ago, I came across this fallen poplar (Populus x canadensis). At first glance, I thought it was just doing what poplars do rather well – break. However, a closer inspection revealed not only a sporophore of the fungus Laetiporus sulphureus, but very extensive brown rot at the basal zone. It also appeared the tree was largely dead. Such factors certainly explain why this individual failed, whilst the others around it did not.
