Identity HelpPhallus-ite?

Here's something I've never seen before. I inherited it as part of a collection. The owner did not know what it was. Phallus shaped rods, with a sprinkling of pyrite... Is it a pseudomorph?

Looks like a tangle of quartz crystals with some sort of overgrowth. I doubt that it's a pseudomorph. Toward the top there are two or three parallel sheets of material that may represent water levels. Some of the rounded caps on other crystals could be "rafts" of the same material that didn't attach to anything at the time they formed but ended up draped over the terminations of crystals as they sank or as the water drained away. The overgrowths could be a post-mining deposit (such as drilling mud) that formed over natural crystals, or the whole thing could be natural.


Interesting piece.

Should I try putting a bit of water on part of it to see if it is mud?
