What is this plant?

I was growing a small lily like plant in my room and when it flowered it grew a deep red flower which absolutely stank. It is about 15cm (6inch) ling and has like a round part and then a bit of a tail with a large almost black stick coming from the centre. I really have no idea what this plant is and it is really hard to find information on the internet when they ask for the name of the plant to search for it?!?!!!!!
