I spent some time with this one and a had difficulty coming to a satisfactory conclusion. All the clues were giving me several options none of which seemed right at first but a photo of a Toninia following a saxicolous crack got me finally to the right group. Other groups considered were Catillaria, Cliostomum and Lecania. The reaction of K+ y put Cliostomum in the picture but it turned out to be a red herring. The spores are 17µm long and 3-septate. The paraphyses are with a swollen apex with pigmented tip.

Oxyrrhynchium hians is a common pleurocarp which can be identified quite readily with care and a good hand lens in the field. With the example below I could see through the hand lens the nerve extending past the half way mark but not reaching the tip and the margin of the leaf toothed. A good feature for O.hians is the leaves being spaced out along the stem.
