Allophane has short-range atomic order, it is a mineraloid, rather than a mineral, and can be identified by its distinctive infrared spectrum and its X-ray diffraction pattern. It forms waxy botryoidal to crusty masses with the colour varying from white through green, blue, yellow, to brown.

This specimen shows great under UV light. I will get some pics of this up soon.

I acquired this specimen from Tony at The Mineral Store Australia at the August 2016 Sydney Crystal Show.
