Maybe Mark, but without microscopy it is impossible to determine it. According to a local expert, it is most probably M. revincta, considering that it is on a chestnut or oak trunk but all the species of this genus are very similar. Apparently, M. cinerea prefers rotten hardwood like beech, birch and hazel.
