Mold started to grow exceptionally fast on a leftover chocolate cake hanging around the kitchen. I think the mold must have grown so quickly because it was a very very good chocolate cake, and not full of preservatives. Note the cool, gnarly little flower-like dealies at the ends of the mold spores.
The total area for the entire patch of mold was smaller than a dime, and it just appears to be a velvety, short, soft whitish-green fuzz. the portion I have shown here is a little smaller than a grain of rice.
Send me your suggestions for something tiny that you'd like to see big.
