No specimen available

Fruiting on old rotten apple wood. At first I thought it was a cool looking bluish gray crust. After downloading the photos onto a computer it looks more like a small cup fungus.
UPDATE 3/12/2012: It’s a basidiomycete with rather large clamps on the hyphae. Spores 6 × 5 µm .
See page 206 in the Fungi of Switzerland vol 2.

Stigmatolemma urceolatum, page 206 in Swiss II looks like a close match. Including the crystals on the fruiting bodies.

Also in S.C.

I just found M. anomalus in S.C. yesterday. First time I have noticed it (it’s really small)…
On old oak bark fallen off the branch at Quail Hollow.

Darv’s looks more blue-gray. Really cool fungus. Nice find, Darv!

darv may be too small for this, what do you think?
