The Flora of Derbyshire by Clapham describes its status as 'occasional' which is repeated in the Derbyshire City Council - Flora of Derbyshire. The distribution map (reproduced below) shows scattered records mainly in the East of the County.
I thought the host tree was a Sycamore but not too sure, its right by the roadside next to the river just North of High Peak Junction.
The sun appeared just as I was taking the photo which added a bit of colour.
