Edible Morel?

Any ideas what this peculiar looking specimen is - about 4.5" x 2" wide?
Edible morels? Here are some views of it in case someone can positively identify it as the edible variety! My slight anxiety is triggered by a local family mistakenly eating what they thought were chanterelles, winding up poisoning themselves so badly that two or more of them are on a kidney transplant list, sadly.
The stem/base is attached at the base, rather than rising to join at the top which seems to be a feature of the false morels. Despite having had the great P.D. Orton as my biology tutor, I am embarrassed to admit I learnt little about what is edible and what is poisonous, and he himself absolutely refused to eat any fungi at all!
