About three months had passed since I last wandered around looking for mosses on a flyover near Shoreham and I should really have gone back sooner. In March a Bryum was fruiting profusely under galvanised crash barriers by a farm track but the capsules were too immature to check for Bryum pallescens which is partial to spots such as this which are polluted by metals.
The Bryum was now dry and brown but some capsules were just hanging on. Dissecting them back home I found a peristome on some specimens and the inner peristome had long perforations as in B. pallescens. I sent some to Tom who confirmed it.
It wasn’t a good time to check for other mosses but the chalk-hill flowers were at their best with masses of Kidney Vetch, some Pyramid Orchids and one spike of Broomrape.
A scrubby slope to one side and a grassier slope down to the bypass were covered in Common-spotted Orchids. The latter slope had patches of dried up moss which included Thuidium tamariscinum, Eurhynchium striatum and Barbula convoluta.
Still not up to 40 species for this tetrad so there will have to be a third visit.
