An impressive patch of Atrichum Undulatum with abundant capsules demonstrating the characteristic long beak on capsule lid.
In the field I thought this was going to be Sphagnum contortum, but stem section rules this out. All fits with Sphagnum Subsecundum again instead.
Photo 3 is showing a close up of the classical “Crabs claw” appearance of the end leaves on a branch. Our smallest Sphagnum in the UK.
Another example of sphagnum Austinii. Raised hummock which is hard when you press on it. Very tightly packed. What is particularly unusual is the presence of capsules which are meant to be very rare. Could be that the capsules are coming from other species mixed in. Can certainly see S. Capillifolium.
