Notes:
Growing on the side of a hardwood log. Odor indistinct. Fruiting body pliable, drying to a very tough and dense consistency. All tissues appeared inamyloid but was only able to find 1 spore, which could have been a contaminant.

Growth on hardwoods, cartilaginous/flexible basidiocarps drying to a very tough consistenc. All parts inamyloid. There are more but these were relevant to my particular collection.
