There are many specimens of this Grimmia pulvinata moss on the bridges, but this is the first one I've seen with capsules. The moss is around 2 cm. in diameter, and the capsules are around 2mm.
This is a very interesting one. I take it to be a gelatinous lichen. There were a number of specimens. One or two were 'sharing space' with mosses.
Collema auriforme
These are the buds of the Sycamore. This specimen is an enormous tree. The bridge is well over 6m above the water, and this tree was easily another 20 metres higher than the bridge. I had to use telephoto, but the buds are quite clear.
