Recognized by sight: It looks like it was growing in very cold conditions and the cluster growing from wood are common characters for Flammulina. However, I thought this species was broken up a few years back (perhaps by Ron Peterson?). This one has a much paler stipe that typical F. velutipes.

I just found the following on Ron’s web page (http://www.bio.utk.edu/mycology/People/petersen.htm ). The short story is that there are probably multiple taxa, but they have not been clearly differentiated yet and even once they are it sounds like they probably interbreed at least to some extent.

“Our latest big project concerns the “fuzzy-foot mushroom” (Flammulina velutipes and relatives). We have attacked the poor, defenseless genus from the following flanks: 1) Scott Redhead (Ottawa, Canada) has examined fruitbodies, and has concluded that there are several additional undescribed taxa within Flammulina; 2) Petersen finds the same general conclusion using compatibility experiments; 3) Karen Hughes and Andy Methven have produced phylogenies based on DNA RFLPs and DNA sequences, and they show the RELATIONSHIPS between these taxa, not just their similarities; and 4) Nadya Psurtseva (St. Petersburg, Russia) has grown the cultures on agar media for physiological characterization.

Two things are clear: 1) lots of the physiological literature (i.e. how to fruit the mushroom; the effects of light, temperature, humidity, etc.) have NOT dealt with the mushroom named in their titles; and 2) most of the taxa are NOT clearcut, but interbreed or hybridize at low levels, presumably in nature. This makes our man-made taxonomy somewhat muddy."

Added separate observation for Daldinia

Is probably the dark fungus in the close up.

That is cool

Looks like it coming from another fungi. It is really small? the brown thing in front of the gilled mushroom looks a lot like some sort of a Hypoxylon.
