Blantamold

While I do not myself indulge in the reading of children's books, I have been led to understand that the Harry Potter series, by British authoress J.K. Rowling, met with some success in the publishing world in recent years. The word blantamold stems from that franchise, having circulated with alarming rapidity in London circles - with apparently nothing better to do - prior to the release of the sixth novel. I leaned on various sundry young acquaintances for the following explanation. Perhaps you can make sense of it (I most certainly cannot):

Blantamold is a fungus that grows upon the mortal wounds of those whose death is a result of something called the Imperius Curse. It was rumored that, in The Half-Blood Prince, a villain absurdly named Draco Malfoy was to acquire some of the fungus ultimately from the corpse of someone else called Broderick Bodie. The lethal stuff would have been originally collected by Dementors (whatever they are) at the direction of a Lord Voldemort, shuttled thence to the villain Malfoy's devious father Lucius, and on to his son, who was instructed to introduce the blantamold in the form of dried tea, or something, anonymously gifted to the hero, Harry Potter. Blantamold was said to induce the poisoned to fratricide, matricide, patricide, or infanticide. Evidently, it was hoped by Malfoy et al that Potter would exercise the third of that unpleasant quartet on a sage called Dumbledore, who was - I am told - the nearest thing to a father figure the unfortunate boy had. In so doing, the child would vilify himself while erasing an obstacle to the "Dark Lord's" triumphant return to power. I don't know. Maybe it means something to you.

Though Rowling is mute on the subject, it is conjectured that, thinking it overly macabre, she abandoned blantamold, leaving it, I gather, to grow benignly on Broderick Bodie's fatal Death Snare wound.
