The oxalate glushinskite occurs at the lichen/rock interface on serpentinite colonized by Lecanora atra at Mill of Johnston, near Insch (a town located approximately 28 miles from the city of Aberdeen) in Kincardineshire. It is found in a creamy white layer intermingled with the hyphae of the lichen fungus. It consists of crystals mainly 2 to 5 µm in size showing a distorted pyramidal form, often with curved and striated faces.
