tell me what it is

I spent most of the morning up to my elbows in the drain so it is also nice to have some nature notes to report. The man came to repair the washing machine at the second attempt but also commented that the drain was blocked which was one of the reasons water was flushing back into the sump on the machine. Would you believe there are 15 joints between the washing machine outlet and the main drain pipe including the sink and the butler sink. Being plastic, pressure on one to try to undo it bends all the rest out of line. In fairness to the washing machine man I did clear a full bucket of foul smelling gunk from the pipes and eventually managed to put all the bits back in place with no leaks! ........ but still the washing machine won't work. There must be another blockage further down the main pipe which runs along the back of all the kitchen cupboards and I just don't have the equipment to get that far down.
So it was pleasant to get back in the fresh air with reindeer Hugh and across the fields and woods which brings me to the nature notes. For those who know the area "the sheep are back". The flying flock has returned to the chase although they are grazing a new area so I didn't see them at first. And then there is the picture (assuming I manage to upload it) which will make this whole blog a bit pointless if I can't as I am now going to ask you to identify it. It first appeared about 4 years ago in just one place but I now know of 4 places that it has colonised and this morning it just seemed to be coming up everywhere. So if you know what it is, whether common or rare, just add a comment to the blog to let me know
