Are Fissidens fontanus and Phoenix Moss the same thing, or are they different?

[Akeath]

I'm having trouble telling. Some sites list Phoenix Moss as the common name for Fissidens fontanus, but I was checking the swap-n-shop here and some people were selling both Phoenix Moss and Fissidens fontanus on the same thread under different pictures, implying that they are different plants. Are they the same plant? If they aren't the same plant, what is the scientific name of the other Phoenix Moss and how is that plant different from Fissidens fontanus?

From my searches for info on these two species. F.fontanus is a US species and the other is a species from Singapore. Both are Fissidens family.This should help a little. http://www.aquamoss.net/Moss-List.htm
