These guys obviously like my lawn. Perhaps it's because I've a large birch and beech tree growing nearby. The mushroom bible (Roger Phillips) says they grow to 12 cm. On my lawn they can grow to at least twice that size - this one was 29 cm across (the lens cap is 8 cm).
If I cut the grass at this time of the year I have to remove these mushrooms before I mow or - as I've discovered the hard way - they make a real mess.
I cleared them yesterday, the second time in four weeks, and filled two buckets...
... the mushrooms weighed 9.5 kg.
Why couldn't they be ceps, or chanterelles?
