Early in April each year a patch of Morels spring up in the garden. Sadly, these are not the sort-after delicacies which mushroom hunters prize. Those in our garden are the Semifree morel - Morchella semilibra, which I believe can cause stomach upsets if eaten.
They can be identified by the lower part of the cap being free from the stem.
The animals enjoy eating them, however, and they quickly are nibbled away. There must have been a couple of dozen of them this year.
