Caught this guy boring into a shelf fungus. Not sure if it was after the fungus or the Ciidae in it, or something else entirely.

I altered your image.
I brightened it and boosted the color saturation to give it a closer resemblance to the image I linked in my comment below. I also clone-stamped a few white specks off it. If you don't consider this an improvement, simply click Edit and reload your original.

 
Can you click on your name
under the image, which will take you to your contributor page, where you can edit and tell us more about yourself?

Extremely rare!
Congratulations on your find. I had seen an image of this beetle before and found it here along with a nice writeup. It looks like you may have added to the natural history of the species with your observations.

If you care to shoot a ventral and a side view, they would be most welcome as well. In case you don't already have a technique worked out, what I've done for shooting ventral views of pinned specimens is stick the head of the pin into a small lump of modeling clay to hold it upright.

 
Thanks
I'm glad you like it. I thought I'd add it first because I didn't think anyone else would get a photo of one. When I tried to look it up it was a little difficult because I wasn't expecting it to be rare. But once I found out what it was I went back and grabbed the fungus it was going into. I wanted to dissect the fungus to see what it was going after, but decided not to. I'll try to get some more shots of it if I can; I have to use my friend's microscope. I'll also try to get some pictures of my other specimens that aren't already on here.

 
Do you still have the fungus?
I think it would be worthwhile to get an ID on it. It could be an important missing link in this beetle's life cycle. Then I would go ahead and see if anything was living in there. Maybe it was burrowing in to lay eggs. The larvae must be undescribed for a beetle so rare. That fungus or others of the same species may be home to larvae unknown to science.

 
Yeah
I think it's around here somewhere. I'll have to dig it out and look it up. I'll probably go to the woods where I found it this spring and look for more of the fungus.
