I am (unfortunately) surrounded by sycamore trees, their leaves are covered with large black spots.  I am sweeping them up.  Is it safe to bag them up to make leaf mould or is it safer to put them in my council compost bin?
Thanks for any advice.

Have a look at http://hedgerowmobile.com/tarspot.html  This is a fungal disease which only affects a few tree species and then does them little harm.

So bag them up!

Cheers,

Many thanks.  And my fungus now has a name!
