This one's got me beat.

There's a lot of these on the ground in the Camellia Walk thinly
distributed over an area roughly circular around 3 - 5 metres dia. The
concentration would indicate a source nearby and they look like
they've blown off a tree but I can't find the tree. Over and around
these objects are mature Oaks, Ash, Sycamore, Beech, Douglas Fir,
Cedrus deodora. Can't see any Birches or Willow nearby and not much of
an understory. If I had an idea what they were I could refine my
search.

Whoever gets this right will have the reward of seeing me looking
pretty damn silly.
