Tiny beetles on polypore - Nanosella

Tiny beetles on polypore - Nanosella
Pelham, Hampshire County, Massachusetts, USA
October 8, 2011
Size: 0.35 mm
I didn't realize beetles could be quite this tiny--I thought they were springtails before I saw them through my lens. There were a dozen or so on the underside of a fleshy, white polypore, evidently feeding on the spores as they entered one pore after another. I guess they must be ptiliids, based on this info from the guide page: "the smallest known beetles, most species being under 1 mm, and the smallest known being 0.35 mm".

Edit: The fungus is Tyromyces cf. chioneus. More photos here.
