Fungus or alga?

The blackberry-purple plant in the pictures above has completely defeated me. It was growing on a sheer 'cliff' of Purbeck limestone in a shady gill south of Burwash Common, East Sussex and had a texture and shape similar to a cup fungus. There were a few more higher up the bank where the limestone was covered in a very thin layer of moss, but I saw them nowhere else in the gill.

A mycologist friend has suggested they might be an alga rather than a fungus, but that is as far as I have got. If anyone can suggest what this might be, or who else I might ask, I would be very grateful
