Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
See where your coming from, however, on Googling Spinellus fusiger I find that it as shown in the other obs, a parasite of other fungi. Looking again at the other obs, and other on line images I noted that the filament type stems are white/ish, whereas those in my image are black, and more elongated. Another point I have been remiss in not mentioning is that it does not see the light of day that often, the bin being covered. Unfortunately I could not make out what it was growing on, it could quite well of been parasitizing some of the other molds,(I didn't know to look at that aspect at the time). Having said that I am sure, somewhere in my archive, I have an image or two of Spinellus fusiger,(ID down to you), growing on a toadstool.
Have a good Xmas, and may 2013 bring you all you wish for...

I agree that this is not a Spinellus - which, as the name suggests, have stiff, spine-like sporangiophores ("stalks"). They are all parasites of toadstool fruitbodies, usually Mycena.
From the very tall sporangiophores and possible metallic look, the fungus here might be a Phycomyces species, but this is pretty much a guess.
