Coffee beans are very moldy in and of themselves, and coffee contains natural sugars that feed and encourage the growth of molds.
Good luck.

When you try your hand at mushroom growing yourself you know that they are both organic and that they will benefit the health of your family. In this day and age when so much of our lives seem controlled by the mechanized and the artificial, home grown mushrooms can provide a wonderful source of health building protein for your family. Best of all, this wonderful food is easy, and indeed almost effortless to grow. There are starter kits available that make the whole process extremely simple without spoiling the organic aspect of things in any way. These starter kits are an excellent way to learn the basics of growing mushrooms, and I would certainly recommend them if you have never grown mushrooms before.
This is a step by step guide you can use to start growing mushrooms at home http://www.goobypls.com/r/rd.asp?gid=573

"Sir Alexander Fleming discovered penicillin at St Mary's Hospital, London, on 3 September 1928 after leaving a dish in his laboratory one summer. "
"RSC spokesman James McNish said: "The culture that developed on Fleming's laboratory dish has much in common with those ageing, ownerless coffee cups languishing on shelves and workstations in British offices and in factories."
So, we all have antibiotics laboratories in our offices, homes, campers, etc. Nice to know!
BUT... you asked why it grows so fast in coffee in particular...
The answer is that coffee beans reutinely have bacteria on them, and in them. This is usually destroyed in the crushing/brewing process because of the high heat involved. However, some hardy fellows and ladies survive this Dante's inferno brewing in your pot everyday.
A brewed cup of avg coffee has a pH of around 5.0; slightly acidic. Molds and fungi have been known to favor a slightly acidic medium in which to grow. The coffee is warm, wet, and steam causes humidity. OOOhhhh I am describing a parasites dream home! Wait it gets better! - - - Add sugar and creamer to the cup and the parasite now has all the neurishment it could ever dream of right here, where you put it! Milk for lactose which metabolizes in this hot wet environment into glucose (sugar) combined with the sugar our illustrious coffee cup abandoned with no hope of returning to it's masters mouth and it's ultimate demise starts to rethink things. . . . . HEY!! Maybe she left me here on purpose, with all of these factors contributing to my own growth and prosperity as a penicillin factory maybe that is my future!!
And so the cup of coffee, we will call her Aribecky, desides her master has commissioned her to aggressively grow mold spores in order to help humanity.
How could any self respecting cup of coffee not draw that same conclusion, given that the circumstances overwhelmingly support such a hypothesis. Too perfect to not be true.
SO to answer the short way, the conditions are supremely optimal in a std cup of coffee for growing hydroponic penecillin! That is why it happens so quickly, sometimes over a single night if the room is warm.

odd as it seems, Ive read that there are certain microorganisms that grow specifically in coffee. You would think the acid in the coffee would kill any micros, but life can adapt to just about anything on the planet.
