Syntrichia ruralis

This delightful moss was picked up from the ground, again in Inverkeithing harbour, where it grew with other mosses on a concrete base of a demolished building. At first I thought it might be ruraliformis but had to accept in the end that it probably wasn't (see factoids below). It is at least ruralis S.L. I now realise the leaf tip shots I took are on another camera!
