Mn2+(C2O4) · 2H2O
White to grayish white
For Marie Louise Lindberg-Smith of the USGS.
The Mn analogue of humboldtine.

May appear as a dehydration product of falottaite (Mn-oxalate trihydrate).

An orthorhombic polymorph is known as a synthetic compound (Huizing et al., 1977; Lethbridge et al., 2003).
