Before the frosts come (and they are late this year) the woodlands are full of fungi. These pretty little mushrooms remind me of some kind of fairy village, the stuff of childhood fantasy books perhaps. (I always loved 'The Magic Faraway Tree' by Enid Blyton.) In fact these are not so innocent and could cause a very nasty tummy upset and even paralysis, if you ate them. (As far as I can tell, anyway - I'm not an expert) they are Sulphur Tufts [Hypholoma fasciculare] whose purpose is to speed the decaying of old wood.
