Tapiaite forms tiny clear lath-like crystals less than 0.03mm in size. Impossible to capture with my photo set-up, these crystals can nonetheless be seen in the photos as all the hundreds or thousands of reflections all over most of the matrix. It is associated with light bluish green Joteite. This is a fabulous, rich specimen.
This is the type and only locality for both minerals!

Mercury has not been mined in the USA since 1992 when the McDermitt mine in Nevada closed. It is now only produced as a by-product from gold-silver mines. Nonetheless, the USA is the leading exporter of mercury since it is still produced through secondary recovery programs and recycling. A 76 pound mercury "flask" averaged $550-650 in 2008 (USGS). At one time the USA had many mines namely in California. Terlingua, Texas had producing mercury mines. Terlinguaite, like this specimen, was a chief ore at Terlingua. This is an old Carleton Davis specimen with tag.
