Clustered Toughshank (Collybia confluens)
This is a widespread and very common fungus species found in woodland in dense tufts on tree stumps and other dying wood. Mainly associated with decidous wood but ocassionally occurs in coniferous woods as well. Pale coloured with a touch of darker shading towards the top of the cap which is usually only an inch or so in diameter.
My book does not say whether it is edible or not but does say it has a faint taste of mushrooms so presumably someone, somehwere has eaten them at some stage and survived to tell the tale.
