General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Interesting stuff that if you try and pick up when wet, barely sticks together. Very slimy.
It seems to be 99% water because it dries out soon after the puddle it's in dries up.
The colonies shown here are around 10 to 50mm across.
The colonies can be quite thin and look translucent. Overall a very dark green colour.
These were all taken at the same time in & around a small rock pool, after some rain, which is normally dry.
