I bought it a few weeks ago, just termed as 'fern'. It seems to like my terrarium conditions and is growing very well.
In fact there have been lots of new growth in the last month from many of the inmates, I am sure the abeyant light of spring and early summer has caused this big upsurge in activity.
However over the last few months, I have also seen a decline in several of my wild collected moss species. I think the consistently warm humid conditions have finally had a dire effect on them!
