The way I read the abstract was that they haven't discovered any sporophyte for the 'Süßwassertang', yet. I think this doesn't mean that none exists. And if Süßwassertang =
L. lineata, then the sporophytes should look the same.
What I've understood of my friends research dealing with plant DNA sequences is that you can never be 100% sure. 97% similarity is very high and -
depending on your species concept - two samples with that high similarity can be taken as one species.
That was very interesting about the NA gametophytes. I hope A Hill reads this as he's the moss man of the PTF - collecting in the wild and all.
