Green elf cup fungus

Have just spent two days with John Wright on a fungus foray - absolutely fascinating to spend time with such an expert.  This is chloraciboria aeruginascens, a saprobotic mushroom.  I shall never scuffle through the leaves again with such abandon - we found 68 different specimens the first day on Powerstock Common and 69 the second day on the Kingcombe Meadows Nature Reserve in west Dorset
