Strange red balloons?

[The Escaped Ape]

A quick message for Horge Cortes-Jorge Jr. Could you check out my posting in the macro-algae/marine plants forum. Do I have Botryocladia skottsbergii in my tank in your opinion (he asks after having consulted your page on bubble algaes)? Alternatively, check this link for a picture.

What's your expert opinion? I'd be grateful for your views.
