Can you tell us more? Sap of which tree/plant? Can you be sure it is sap?

This is a 'frost flower' or 'frost beard' - see http://en.wikipedia.org/wiki/Frost_flower. I see them commonly in very cold dry frosty weather, often in abundance, and often very beautiful, and usually on dead cut wood. The link gives an explanation for a live plant, but I deduce that water in the vessels in a dead stem will also freeze, expand and then act as a seed for water in the air to extend the threads. A physicist will need to explain how they take on the very smooth parallel curves and how they frequently maintain the microscopically thin dimensions.

Fascinating! Next time you see one, can you take a picture and show us?

I believe this to an unusual phenomenon, particularly in this particular form.
The comments above are all very interesting but Murdo, you didn't take up the suggestion, made by Jonathan, all those years ago - so?
I have ID'd it and hope none of you mind, it's time this gathered some more interest.
I cannot place it in Other Organisms of course.
