It’s been a while since I’ve posted anything fungi-related so I was quite pleased to spot these examples around a tree stump near a local railway bridge, a stump that was deliberately cut down some time ago and had poison plugs hammered into the stump to try to prevent regrowth.

The poison may have stopped the tree re-growing but it certainly hasn’t deterred the fungi. In fact, these are probably the healthiest examples of Dead man’s fingers (Xylaria polymorpha) that I’ve ever seen. I think you can see how they got their name – they really do look like blackened fingers reaching up from under the earth!

In Fascinated by Fungi, Pat O’Reilly explains that this is a species of flask fungus, a type of ascomycete that releases spores from the exterior surface of its relatively large fruiting body – another example is King Alfred’s cakes (Daldinia concentrica). The fruiting bodies of Dead man’s fingers can grow up to 8cm tall, are generally club-shaped, and grow from buried hardwood, usually Beech, though if I recall correctly, this particular stump was a Field maple.
