"Honeycomb" is just a name I coined to describe the figure in the wood. This is pignut hickory that fell and has been laying on (or slightly off) the ground for years (I suspect over 25). The honeycomb pattern is formed by little pockets of decay - similar to spalting, but with a cellular look and no black lines. I've harvested quite a few hickory trees, but only come across 3 with this figure in them.What causes the hickory to do that? I've seen some hickory and never anything like that. Is Honey Comb a type of Hickory?
