Catalog No.: A Bob Janules specimen
Notes: [tm] Visually I would have identified this as leucophosphite. Bob's micro box label has phosphosiderite. I am accustomed to seeing phosphosiderite as blue or purple-lavender balls or as stubby prisms. However, mindat.org as several photos of phosphosiderite with this habit. An EDS would settle this, as leucophosphite requires K, but phosphosiderite does not.
