We travelled to Oxford on Saturday, ostensibly to collect a greenhouse that Arachne had decided she wouldn't continue to use in her own back garden. The plan was to dismantle it and bring it back to Bedford in D's van. Arachne had already removed and stored safely all the panes of glass, all that remained to dismantle was the aluminium frame. We discovered these Pixie Cup Lichens growing happily on the frame and recorded them for posterity.
