Grimmia orbicularis

Today's photograph of my samples from Coedffaldau, which clearly show the differences between Grimmia orbicularis and G. pulvinata. Below, from the same day, Lophozia bicrenata growing in an extensive mat of hepatics at Bryn-melyn sandstone quarry (SN73781134), the main associates being Solenostoma gracillimum, Diplophyllum albicans and Nardia scalaris. The distinctive leather / cedar-wood smell of my sample is remarkably strong for such a small plant, even when dry. This character, when coupled with the compact shoots with golden-brown gemmae, make field identification straight forward.
