I'm thinking that it is some sort of cress.

Bracket fungi is neither a genus or species, it merely refers to the polypores and tooth fungi that grow shelf like on trees.

Bracket only describes the general shape of the fungi, and not very well here. This specific subject has teeth on the bottom, which means that rather than falling in with the polypores (like most bracket fungi do) it falls in with a different classification of fungi entirely (see http://en.wikipedia.org/wiki/Hydnaceae). Due to the increase in the use of genetics over the past decade the taxonomic arrangement of species has also changed, so the shuffling has placed some fungi with teeth under the order Polyporales.

I do apologize for the length of this post, and I hope you don't feel I'm talking down to you on this one. I'm a bit of a mycologist, kinda makes me talk about fungi a bit.

This one is cultivated it is on the campus of Appalachian State University. I'll be posting up some others that I took on an outing to Hungry Mother State Park in VA presently.

Appears that this is a moth, not a butterfly.

Specimen too old for me to tell what it might be by this photo.
