Candlesnuff fungus (also know as stagshorn fungus) grows as groups of fruiting bodies, up to a couple of inches tall, on dead hardwood – sometimes it seems to be growing directly out of the ground, a sign that there is burried wood present.
It looks a bit like the wicks of unlit, part-used candles, and, on closer examination, branches in a way vaguely reminiscent of antlers.
It is common. While it can be found at any time of year, it is most visible in the autumn and winter.
