Local wasteland.
This Xylaria hypoxilon - Candle snuff fungus - was growing on a piece of buried wood.
Sunny intervals.
A late head of Shepherd's Purse - Capsella bursa-pastoris.
And growing through the Shepherd's Purse, Common Mouse-ear - Cerastium fontanum. I'd normally expect the tips of the petals to be more deeply cut than these.
This ungainly lump was growing at the base of a vertical ditch. I'm pretty sure it's the bulbils and emerging shoot of Lesser Celandine.
Thanks to Gill for the correction.
