- Spiny refers to the caterpillars appearance, which is indeed very spiny as well as colorful. And the spines deliver a mild sting. The spines are hollow and contain a toxin; when contact is made with the caterpillar, the spine breaks off and sticks into the skin, delivering the toxin.
- Oak refers to one of this caterpillar's foods.
- Slug is another reference to the caterpillars appearance, which is slug-like. There's a whole family of slug caterpillars (Limacodidae), with about 30 species in eastern North America. The head is covered by the fleshy thorax, and instead of legs and prolegs, slug caterpillars bear seven pairs of suckers along their abdomen, which causes them to glide instead of crawl.
- Moth, because everything else in the name refers to the caterpillars.

They look very different at first, as in the above photo.

There is a very similar moth called the Pink Prominent, Hyparpax aurora in the family Notodontidae, or the Prominents.

Eastern Comma: head with black and white spines. Spines on the back of the body usually light colored with darker tips.
Question Mark: body spotted white, with cream to rusty strips.
I've been finding these caterpillars on Stinging Nettles (Utrica dioica). With the spines with the food, it seems like they might be unpleasant to touch, but the spines are harmless. Maybe I've never really looked before, but it seems like there are a lot more than usual (it seemed like there were more of the Comma, and/or Question Mark butterflies in the spring too).

Stinkhorn - Phallus sp.
Spring Agrocybe - Agrocybe praecox species cluster
Witch's Margarine - Ductifera pululahuana
A lot of features indicate a species of Pholiota including: growth on wood, brown spore print, scales on cap, ring zone on stalk, and scales on the stem.
The scales on the cap were sparse.
As were the scales on the stem and the ring zone.
In general, Pholiotas are larger mushrooms. It also had a snapable stem, which is a feature mentioned in many guides of mushrooms in the genus Psathyrella, but the spore color is usually darker (purple-brown to blackish). Maybe I would be better off leaving it as a LBM. Whatever it is, it was part of a very attractive log tableau which also featured other fungi, moss and possibly even a slime mold.

moth watching parties on our porch. Though mostly small and brownish, I've been surprised at how many different species have showed up in our Minneapolis backyard. The moth above is a Three-patched Bigwing, Heterophelps refusaria, family Geometridae. Text below refers to moths pictured above the text.
