I left these large logs from a dead elder tree in the corner of the garden and they attract a lot of wildlife; plenty of insects and even a hibernating toad.
Wood Ear Fungus (aka Jelly Ear Fungus) loves to grow on Elder deadwood, and there’s a good growth of it here. It sends out new fruit-bodies in the winter, which then darken and dry out during the year. The young growths are edible, a bit like black fungus you sometimes find in Chinese food; not much flavour apparently but an interesting texture if cut into strips in soup or salad. Will have to give it a try sometime.
Another fungus, this time on the dead stump of the same Elder tree, is Elder Whitewash (Hyphodontia sambuci), which appears as a white coating on the dead bark.
