This cup fungus grows on the ground in the late spring. In this case, the scientific name is more fun than the common name! :)
(pron.: hi-fee), decompose organic materials and consume them until the mold is ready to reproduce. It is then that the mold becomes visible, when the the spores mature and cover the fruit, cheese, bread, my compost box, etc. I did clean the box after taking this picture! :)
Leave an orange around long enough and this is what will happen! Mold spores are always present in the environment. If they land on a suitable surface, such as this orange, they will begin to grow. The mold starts out white, but as the spores mature they turn a grayish-green. Penicillin information
