       This fungus occurs on dead Quercus in Costa Rica and on oak and other hardwoods in North America.  The species has long pendant spines that originate from a slightly branched base.  White at first but developing pinkish ochre colors with age.  The specimen illustrated here was found in Tapanti National Park on a downed oak log.
