Michael and I had a pleasant walk around the water this morning to see the Pithya vulgaris again and we were very pleased to see it beaming so brightly on such a cloudy day. We estimated that there must have been well over a thousand individual fruiting bodies on the recycled Christmas trees around the reservoir.
