I really enjoyed this foray - a wonderful site bathed in bright late October sunshine.
Cyathus striatus (Fluted Bird's Nest)
Marasmiellus/Gymnopus villosipes - found here and at a few other sites new to the UK a few years ago.
Hygrocybe reidii (Honey Waxcap)
Mycena aetites (Drab Bonnet) - a Mycena sp. found in grassland and smelling of bleach. And, for the record, I think that it's actually pretty smart!
Hygrocybe chlorophana (Golden Waxcap)
Amanita muscaria (Fly Agaric) - surprisingly found under Beech rather than the usual Silver Birch!
