This fungus has appeared in my "new" meadow, seeded last Autumn. The spores have probably arrived in the seed mix from Goren Farm, near Stockland. That farm has a long history of meadow management, hence the probable reason why the fungus is in the seed bag. Meadow Coral is not distributed widely across the UK but is common in local pockets on unimproved grasslands.
