Crystal System:
A name introduced by Pasero et al. (2010) for a theoretically, potentially new mineral species, the hydroxyl analogue of hedyphane. Dunn et al. (1985) described a hedyphane sample from Långban, Sweden which contained 0.34 wt % H2O.

Now (October 2018) IMA-approved species.
See (RRUFF ID: R070425) and the entry Asbestos hedyphane
