When Mount Saint Helens in southwestern Washington erupted on the morning of May 18, 1980, the stratovolcano spewed a plume of debris high into the earth’s atmosphere and spread ash to at least eleven nearby states. But despite the appearance of a mountain-side extinction event, life was already regenerating. Just 10 days after the eruption, the geomorphologist Fredrick Swanson surveyed one of the lahars with colleagues and noticed something intriguing. In the rubble, fine, filament-like threads had attached themselves to some of the smaller pebbles and stones cast out of the volcano’s center. What Swanson was witnessing was the phenomenon of “phoenicoid fungi,” aptly named in a nod to the mythical phoenix rising from the ashes. Fungal organisms such as these are often the first responders to blast zones and wildfire burn areas where the decomposing landscape serves as a smorgasbord for their biological needs. The fungi used for environmental clean-up come in a variety of shapes and sizes. Oyster mushrooms ... can break down petroleum and hydrocarbons, putting them top of the list when it comes to cleaning up deadly oil spills. A 2023 study conducted in Massachusetts, commissioned by MassDOT, found that there could be benefits to integrating mycelium into the state’s pre-existing stormwater management infrastructure to serve as a filtration system to improve water quality.
