Confessions of a Mycologist

In my defense, I was trying to save the planet.

A group of graduate students discovered a fungus in the Amazon that could digest polyurethane. Instead of sitting in a garbage dump for hundreds or thousands of years, tennis shoes, foam, and insulation could decompose rapidly. Naturally, I wasn’t satisfied with a fungus that could digest only one type of plastic. Some have called it hubris, others, my fatal flaw. And perhaps my thirst for tenure overtook my sense. But what mycologist wouldn’t want to modify the fungus so it could digest other plastics as well?

Through a multi-university research partnership, I received samples of the original fungus, Pestalotiopsis microspore. By the time I finished my genetic modifications, my fungus could digest almost any synthetic polymer. Polyester, acrylics, silicone–you name it, my fungus could handle it. Its mottled white coloration reminded me of the moon, and it had an almost hairy texture, so I lovingly gave my new fungus the common name of moonhair.

Imagine the excitement of the scientific community. People wouldn’t have to change their habits or “go green.” Consume your 300 or 400 pounds of plastic a year, send it to the landfill, and moonhair would take care of it for you. My fungus didn’t even require air or sunlight.

Those were the good days, when I was respected for my work. Every scientist deserves respect. Of course, I wasn’t expecting reverence. Frankly, I was abashed when the covers of national magazines compared me to the Virgin Mother. I suppose the parallels were inevitable: my name is Maria Santos–Saint Mary–I saved the world with the birth of my fungus, and no man was involved in the fertilization of my ideas.

Three years later, the United Nations declared the creation of moonhair an act of biological warfare. Rather than be tried for crimes against humanity, I went into hiding.

I would like to point out that originally it was not a flesh-eating fungus.
