Here\u2019s a hypothetical question.<\/strong><\/em><\/p>\n

<\/p><\/p>\n

\n

Ever wondered what trying one of those iconic red and white polka-dot shrooms \u2014 aka the Amanita muscaria<\/em> or \u2018fly agaric<\/a><\/strong>\u2018 \u2014 would be like? Even<\/em> if its poison could likely mean your last psychedelic trip ever?<\/p>\n

<\/p><\/p>\n

\n

Well \u2014 of course not \u2014 you\u2019re not crazy<\/em>!<\/strong><\/p>\n

<\/p><\/p>\n

\n

But, what if there was a way for you to evolve so that your body could neutralise the poison? Only in exchange, you\u2019ll spend the rest of your life as a squirrel\u2026<\/p>\n

<\/p><\/p>\n

\n

We\u2019re just playing, obviously. However, researchers from Kobe University<\/a><\/strong> in Japan have discovered that Japanese squirrels can pick and eat fly agaric mushrooms safely. And, they enjoy doing so quite frequently! No such thing as forbidden fungi to these critters, apparently!\u00a0<\/p>\n

<\/p><\/p>\n

Japanese Squirrel Spotted with Toxic Mushrooms<\/h2>\n

\n

In Nagano prefecture, Japan, Professor Kenji Suetsugu<\/strong>, along with photographer Koichi Gomi<\/strong>, spotted a Japanese squirrel (Sciurus lis<\/em>) snacking on Amanita muscaria <\/em>many times for a couple of days. It wasn\u2019t just fly agaric, either: the critter\u2019s charcuterie also included Amanita pantherina<\/em>, aka Panther cap<\/a><\/strong> mushrooms. What astonished the team, however, was the squirrel\u2019s ability to withstand the deadly poison<\/strong> that comes with both species of psychedelic fungi.\u00a0<\/p>\n

<\/p><\/p>\n

\n

Professor Suetsugu wrote<\/strong> in the journal Frontiers in Ecology and the Environment:<\/p>\n

<\/p><\/p>\n

\n

\u201cInterestingly, we observed a Japanese squirrel (<\/em>Sciurus lis) routinely feed not only on <\/em>A. muscaria but also on other <\/em>Amanita species that are also poisonous to humans. This squirrel returned to feed on <\/em>Amanita fruiting bodies for several days, indicating that it could <\/em>safely consume the \u2018poisonous\u2019 mushrooms.<\/em><\/strong>\u201d<\/em><\/p>\n

<\/p><\/p>\n

Spores and Squirrels<\/h2>\n

<\/p><\/p>\n

<\/p><\/p>\n

\n

After getting over the initial shock, the team figured out that the Japanese squirrel must have evolved in some way to eat the poisonous mushrooms with no side effects. The new theory? Nature always finds a way. So what if the Amanita<\/em> fungi are actually using the squirrels to spread the mushroom\u2019s spores<\/strong>? Kinda like monkeys eating the fruits of plants and pooping out the seeds later on.<\/p>\n

<\/p><\/p>\n

\n

Suetsugu explained:<\/p>\n

<\/p><\/p>\n

\n

\u201cPerhaps Amanita mushrooms facilitate <\/em>mutualisms<\/em><\/strong> with toxin-resistant squirrels, which can disperse viable spores, while [blocking out] toxin-susceptible enemies, which could negatively impact spore survival.\u201d<\/em><\/p>\n

<\/p><\/p>\n

\n

Mutualism occurs in nature when two or more species benefit from their interactions. It\u2019s a type of win-win, symbiotic<\/a><\/strong> situation for all involved; no predator or prey basically.\u00a0<\/p>\n

<\/p><\/p>\n

\n

\u201cIf so, potential dispersal of fungal spores by squirrels is analogous to a <\/em>seed dispersal mutualism<\/em><\/strong>, in which a plant offers a reward to an animal as a seed disperser.\u201d<\/em><\/p>\n

<\/p><\/p>\n

\n

Amanita Spore Dispersal<\/h2>\n

<\/p><\/p>\n

\n

Professor Suetsugu wants to study the Japanese squirrels even further. This time on a larger scale, tracking the critters\u2019 movements in the forest. Then they recorded if they spread the Amanita<\/em> spores or not. The only way to be sure is to test the squirrel poop for live spores.\u00a0<\/p>\n

<\/p><\/p>\n

\n

The researchers wrote of this new goal:<\/p>\n

<\/p><\/p>\n

\n

\u201cHow do squirrels safely eat <\/em>Amanita mushrooms? What role do squirrels play in <\/em>Amanita spore dispersal? How would squirrel-assisted spore dispersal contribute to the [building] of <\/em>ectomycorrhizal<\/a><\/em><\/strong> relationships within these ecosystems? These questions warrant further investigation.\u201d<\/em><\/p>\n

<\/p><\/p>\n

\n

If the Amanita <\/em>spores can remain intact in the stomach and intestines, then it\u2019s possible that Japanese squirrels could have been \u201cchosen\u201d to spread the mushroom spores. The deadly poison might be intended to block certain animals (such as deer, red pandas, or bears)<\/em> whose guts would break down the spores.\u00a0<\/p>\n

<\/p><\/p>\n

\n

Other creatures, such as the Japanese squirrel, that can survive the Amanita\u2019s defence would be paid for dispersing its spores with a yummy treat.<\/p>\n

<\/p><\/p>\n

\n

\u201cThe ecological roles of fungal toxins remain largely unexplored,\u201d<\/em> wrote the researchers. \u201cOne possible role is to deter <\/em>fungivores<\/a>. <\/em><\/strong>However, fungivores are not always disadvantageous to <\/em>Amanita, because they may disperse intact spores via their digestive tracts.\u201d<\/em><\/p>\n

<\/p><\/p>\n

Amanita Muscaria as Food<\/h2>\n

<\/p><\/p>\n

<\/p><\/p>\n

\n

Did you know that some Japanese also relish Amanita as a delicacy? Though the species is known primarily for their toxic compounds, forest dwellers were the first to consume Amanita as food \u2060\u2014 only after taking out the poison, of course.\u00a0<\/p>\n

<\/p><\/p>\n

\n

In 2000, researcher Allan Grady Phipps<\/a><\/strong> wrote about the ancient Japanese use of Amanita muscaria<\/em>, known locally as beni-tengu-take:<\/p>\n

<\/p><\/p>\n

\n

\u201cThe poisonous fruiting bodies of Amanita muscaria are harvested by rural inhabitants of Sanada Town, Japan. These mountain villagers consume beni-tengu-take as a <\/em>local delicacy<\/em><\/strong>, despite its potential hallucinogenic effects.<\/em><\/p>\n

<\/p><\/p>\n

\n

The Japanese use several methods to detoxify beni-tengu-take, but believe <\/em>pickling the mushrooms<\/em><\/strong> to be the safest. Other methods of preparation include grilling and drying the mushrooms.\u201d<\/em><\/p>\n

<\/p><\/p>\n

\n

Amanita\u2019s Unique Role<\/h2>\n
\n
Amanita muscaria<\/em>\u2019s fantastical look has inspired writers and artists for centuries.\u00a0<\/mark><\/figcaption>\n<\/figure>\n

<\/p><\/p>\n

\n

The recent findings have shone a light once again on the role of Amanita and other fungi in making sure forests remain lush and intact. Professor Suetsugu also pointed out what precisely sets the Amanita<\/em> species apart from other mushrooms in the forest. He wrote:<\/p>\n

<\/p><\/p>\n

\n

\u201cThe representative toadstool <\/em>Amanita muscaria plays an important role in maintaining forest ecosystems by forming mutualistic associations with a variety of trees.\u00a0<\/em><\/p>\n

<\/p><\/p>\n

\n

\u201c<\/em>A. muscaria is also known for the poisonous properties of its hallucinogenic constituents, namely, ibotenic acid, <\/em>muscimol<\/a><\/em><\/strong>, and muscarin. Serious cases of poisoning in humans may involve deliria, hallucinations, seizures, and (rarely) death.<\/em><\/p>\n

<\/p><\/p>\n

\n

\u201cA typical symptom is visual distortion of the size of objects, a phenomenon that formed the basis of the <\/em>mind-altering<\/em><\/strong> events<\/em><\/strong> described in Lewis Carroll\u2019s 1865 novel\u00a0<\/em>Alice\u2019s Adventures in Wonderland<\/a>.\u201d<\/em><\/p>\n

<\/p><\/p>\n

\n

Mushroom Miracle<\/h2>\n

<\/p><\/p>\n

\n

Nature has figured out a way to make Japanese squirrels immune to the deadly poison of fly agaric and panther caps. This makes them perfect <\/em>agents for spore dispersal. More than just their reputation as hallucinogens, these fungi play a much larger role in forest ecology than we\u2019ve previously thought.\u00a0<\/p>\n

<\/p><\/p>\n

\n

From mutualistic relationships with various plants, to helping trees talk to one another, and now this crazy friendship with squirrels? Psychedelic mushroom species such as Amanita <\/em>and Psilocybe <\/em>(aka\u00a0true magic mushrooms<\/b><\/a>\u00a0and magic truffles) sure are a scientific marvel to behold.<\/p>\n
