Foxfire? Will o the Wisp?

For the past 2 nights we have had cold dry weather and noticed these glowing green lights amongst the firs and madrone trees in our yard. At first I thought they must be from a neighbors Christmas light display, those projection lights are all the rage this year, but as far as I can tell, that isn't the case.

Bioluminescence fungi may be the reason. Foxfire. Or, could it be glowing green ectoplasm?
