The pond at Northycote Farm with a thin cover of ice last week.
Uneven surface to the ice near the edge of the pond. Perhaps from gasses given off by rotting vegetation in the pond, the surface of the bubbles frozen before they burst.
Scarlet elf cups are very distinctive fungi, shaped like small cups with a bright red interior and a pale white or yellowish exterior.
They grow on dead wood from many species of deciduous trees.
Supposedly fairly common in winter and early spring, but often hidden in the vegetable litter under trees, or even underground.
These were growing on a pile of fallen branches a short distance from the Ranger Station in the Smestow Valley LNR.
