I believe this is Clavulina cristata, one of the Crested coral fungi, which grew spontaneously on some Malaysian drift wood in one of my vivariums. It's usually considered among the mushroom species. I had to lower the resolution of the photograph in order to upload it, but it's very feathery and pretty. Some people consider it edible, while others don't like the taste, but either way, I'm not going to eat it.

These surprises are one of the reasons I don't "sanitize" wood and soil very carefully.
