Let them spore!
Long Overlooked as Crucial to Life, Fungi Start to Get Their Due
Internet crowns mushrooms the OG lifesavers — but demands proof and protection
TLDR: Agarikon, a rare medicinal mushroom, is now stored in a biobank as scientists push fungi into conservation plans. Commenters hype soil-saving fungal networks, skeptics question the “12 million species” estimate, and everyone shares groan-worthy mushroom puns—because protecting fungi could shape farms, forests, and our future.
A rare medicinal mushroom called agarikon is so endangered it’s being stored for safekeeping at the San Diego Zoo, and the comments went full forest-floor frenzy. The top vibe: respect the underground. One soil diehard cheered that fungi literally built our world and says no‑till farming (not plowing so the soil web stays intact) keeps plants healthier because tilling “kills fungal mycelium.” Translation: save the mushrooms, save the harvest.
But the thread split when someone asked the spicy question: if we’ve only identified about 155,000 species, how can scientists claim there might be up to 12 million? Skeptics want receipts; explainers jumped in with “statistical sampling, folks,” while others argued we’ve ignored fungi for so long that of course the numbers look wild. Drama level: moss-on-fire.
Meanwhile, the article’s big beats got applause: fungi form vast root networks that feed plants, only a tiny slice of these hotspots are protected, and scientists like Merlin Sheldrake (of Entangled Life) and prize‑winners mapping these networks are finally getting their trophies. Also eyebrow‑raising: agarikon’s compounds show promise against microbes and cancer, and may even reduce some COVID‑19 vaccine side effects—cue cautious optimism, no snake oil. And yes, the thread crowned its court jester with a classic: “We’re fun guys!” Groans, upvotes, repeat.
Key Points
- •Agarikon is one of only two fungi species classified as endangered in the U.S. and is being preserved in a biobank at the San Diego Zoo.
- •Studies indicate agarikon has antimicrobial, antiviral, and anti-cancer properties and may reduce Covid-19 vaccine side effects while enhancing immunity.
- •Agarikon populations have declined about 70% over the past century; the Pacific Northwest is considered its last U.S. stronghold.
- •Only about 155,000 fungal species are described, versus estimates of 2.2–12 million globally; limited data hinder conservation listings, as seen with IUCN.
- •Advocates push to elevate fungi in research and policy; only ~10% of mycorrhizal hotspots are within protected areas, though attention to fungi is rising.
