Plagiomnium rostratum

Hiding amidst Lophocolea bidentata at the base of a wall, Cullaloe LNR. Having discovered a Plagiomnium type at Carlingnose NR, this one got a grilling - individual unicellular leaves along the whole margin, no sign of "oblong" aspect ratio cells, and not really much hint of a diagonal due to the near-uniform cell shape.
