Once vibrant and fresh this faded orange infected with colonies of turquoise-white-grey “Penicillium” mold that has penetrated its orange-colored skin and contaminated the wonderful citrus fruit beneath.
Now this orange is also soft where the mold has settled in and the fruit most likely has a moldy “off” taste not the sweet tangy citrus it had before because the mold spores have infiltrated the flesh and juice.
There literally thousands of mold species and these fungi reproduce by producing massive numbers of tiny invisible spores floating in the air waiting to settle down that we only become aware of when they form large colorful colonies.
These fungi colonies grow multicellular thread-like structures called hyphae that interconnect forming what is called a mycelium.
Molds biodegrade natural organic things and are a leading cause of food spoilage unless refrigerated at low temperatures below 4 °C (39 °F).
Never-the-less mold spore contaminated organic things may appear normal because molds can remain dormant for long time only showing itself when appropriate conditions happen for it to do so.
