Dead Man's Fingers fungus
The Ascomycete Xylaria polymorpha, growing on a fallen branch of Sycamore (Acer pseudoplatanus) that has lain on a damp woodland floor for several years. The finger-like structures growing out of the rotting wood are fruiting bodies (stromata) of X. polymorpha; its common name is Dead Man's Fingers. The fingers"" here are about 7cm long. Ascomycetes are the largest phylum within Fungi. They are characterised by the production of asci - club-shaped cells within which the spores develop. Familiar Ascomycetes include truffles and King Arthur's Cakes ( found on ash trees). X. polymorpha is a wood rot fungus of no culinary value. But it is one of a number of fungi that can give rise to spalting in wood - the appearance of zones of different colours separated by black borders. This effect is prized by wood-turners, since it produces beautiful patterns in turned objects such as wooden bowls."
