Brachythecium albicans at Moorlakes Wood

Brachythecium albicans growing on moss-covered, corrugated-asbestos roof in woodland along with Didymodon insulanus, Bryoerythrophyllum recurvirostrum, Hypnum cupressiforme var. lacunosum,  Schistidium apocarpum , Bryum capillare, Tortula muralis, etc... (these are all I could grab from the edge, but looked like there were several other species up there).
