Comments:

A uranyl sulfate hydrate, found in small yellow crystals, this mineral fluoresces yellow under SW and LW. The locality is in Bohemia, the Czech republic. Am Min 82

Associated (mixed) with uranopilite in coating at Jachymov Mine but easy to distinguish via UV-SW illumination by his significantly weaker fluorescent response than uranopilite. (Jeff Weissman)
