I think this might be the same moss as the 'Amano' moss we've been passing around. It's a Taxiphyllum species as is Java Moss...hence the similarities we've noticed between the two. Opinions? http://aquamoss.net/Green-Sock-Moss/Green-Sock-Moss.htm
Hmm... It's impossible to tell without doing a side-by-side microscopic comparision, but the shots of the individual strands actually look like the Taiwan moss that's gone around to me. (Or is that the same as the Amano moss?)
