Mimbletonia fungus

"Mimbletonia Fungus Served At No-Maj Gala Dinner"

- The New York Ghost, 2 December 1926

A Mimbletonia fungus is a magical kind of fungus that, presumably, is somehow related to the rare Mimbulus mimbletonia cactus (perhaps they interact as symbionts).

On 2 December 1926, The New York Ghost reported that a Mimbletonia fungus had been served at a No-Maj gala dinner, in what was likely a breach of both Rappaport's Law and the International Statute of Wizarding Secrecy.
