String Moss (Japan Moss)

This is another moss that was available in our fish shop recently, and was labelled as String Moss (Japan Moss). Initially I thought it was similar to Stringy Moss, Leptodictyum riparium. But upon closer inspection, it was totally different. The moss grows rather long, and it feels rather 'rough' to the touch. One interesting thing I noted is that the growing tip of this moss is black is colour, rather like a black dot. The following pictures show what I mean.

I'll try to tie the moss onto driftwood and grow it properly and nicely in my tank. I'll keep everyone updated in the future on the progress of this moss.
