A Comatricha Species (Slime Mould)

I was looking around our garden, searching for macro subjects but finding nothing much.

Then I picked up a piece of dead, rotten bramble stem lying on the ground.

A group of stalked, brownish objects got my attention.

I have tried to identify it. I am fairly confident that it is a Comatricha species but it has a structure I have not seen in any Comatricha images on the internet or in my books. It is the yellow to pale brown to dark brown, shiny link* between the stems of some of the fruiting bodies.other fruiting bodies in the colony appear to arise directly from the substrate (bramble stem).

  • Not visible in the fourth image and as a pale form in the last.

The field of view for most of the images is 7mm wide.

The stereo is crosseye.
