Many of these specimens will not look like anything of value without good magnification!!

A note on IDENTIFICATION of rare species: unless stated otherwise, identifications of species are based on mine or my source's visual inspection of the specimen. A knowledgeable collector with a good photo library and a good microscope can do amazingly well at species identification, but there is always a chance they are wrong. Even if a specimen has been analyzed by EDS there still may be some uncertainty. I will try to note when there is significant uncertainty with the ID of a species. If you think one of my IDs is wrong, please let me know and I will look into it further!
