Scurfy twiglet

Notes:

Young(ish) and older fruitbodies from left to right. I found it growing on leaf litter underneath a hawthorn tree (I think). There were about 20 of them growing in an area about 1m by 2m both on their own and in small groups of upto about 4. They were fairly small mushrooms, the caps not much bigger than 4cm diameter and stipes about the same.
