Description: This is most likely the Xenophyophore Syringammina sp.
Xenophyophores are single celled organisms. The single cell branches and splits into hundreds of tubes which ramify and interconnect into a complex network. The test builds up as it proliferates, secreting a slimy organic cement. These are the largest structures produced by a single cell.
