Kytrogorgia, also known as cerulean slime mold, was a liquid substance used in mycotoxin, a poison used to kill ex-Imperial Vice Admiral Perwin Gedde at the hands of bounty hunter Mercurial Swift. Kytrogorgia was a tell-tale sign of mycotoxin and was discovered by fellow bounty hunter Jas Emari. It smelled like bitter citrine, or a too-ripe kakadu fruit.
