From my point of view this is friken scary as hell. Cryptococcus gattii was formally known as Cryptococcus neoformans var gattii, Cryptococcus neoformans is one of the fungi that has a significant genome alignment with the sponge, and the alignment scored very high with the BLAST program at the gene bank. I made a spreadsheet showing the significant genome alignments between several sponge species and bacteria, fungi, protozoans, and nematodes.
18s ribosomal RNA alignments with sponges
This fungi replicates by budding and has a capsule composed mostly of polysaccharides , the sponge replicates by budding and secretes polysaccharides, combined with the genomic alignments we have pretty solid evidence supporting the sponge theory folks.
