Leason Wood ramble

A ramble through a short section of the north Gower Ash woods last Friday produced a few records of interest, the best of which were a small colony of Marchesinia mackaii (photos of part of the colony and the rock it is on below, this being only the second north Gower colony I've come across) and a sheep-trodden Hygrocybe calyptriformis in an open grassy area. It would be an interesting exercise to monitor the changes in composition of the field layer in these Ash-dominated woodlands as Ash-die-back takes its course.
