Several years ago, Mort Shurtz girdled this tree as part of a TSI project (Timber Stand Improvement) at Valley Water Mill. What we didn't realize at the time was he was just feeding fungus. Mark Bower, who photographed it, tells me that a forest is just a fungus farm and the TSI is simply feeding it.
Flammulina velutipes, a fungus that enjoys the cold, appearing in the last days of fall. Its cap is slightly sticky with a rubbery feel. It only grows on hardwoods, although if the wood is buried in dirt it may look like it grows on the soil itself. The stem is darkened at the base and has a fuzzy or hairy surface. Its common name is "Velvet Foot" and it is easy to see why in the picture of its stem below.

"In 1993 cultures of Flammulina velutipes were flown on the Space Shuttle Columbia in order to determine how the mushrooms would handle low gravity. Like many wood-inhabiting mushrooms, Flammulina velutipes typically bends its stem near the base, then grows straight up, resulting in a cap that is more or less parallel to the ground--presumably so that spores will fall easily from the gills. Aboard the space shuttle, however, the mushrooms got confused, growing out of a simulated tree trunk at all angles. In other words, they lost their balance." mushroomexpert.com See research at plosone.orgNot bad for a little fungus that ended up growing on a girdled tree at Valley Water Mill.
