NPR’s Scott Simon speaks to Prof. Anne Pringle, a mycologist on the College of Wisconsin, Madison, in regards to the newest analysis on loss of life cap mushrooms, revealing new details about the enigmatic fungus.
SCOTT SIMON, HOST:
Demise cap mushrooms have been within the headlines this week after an Australian lady acquired a life sentence for fatally poisoning a few of her members of the family with the poisonous fungus. However current analysis has revealed new and, frankly, intriguing details about the mushrooms. Anne Pringle is a mycologist on the College of Wisconsin in Madison. Thanks a lot for being with us.
ANNE PRINGLE: My pleasure.
SIMON: You’re employed with colleagues from Yale, Portugal, Germany. And I collect, in your analysis, you’ve found there are some toxins that possibly you’d missed earlier than that they are creating.
PRINGLE: That is proper. So the loss of life cap is legendary as a result of it kills individuals. Individuals can eat it as a result of they mistake the mushroom for one thing that’s edible. And so we have identified for a really, very very long time that the loss of life cap is toxic. However what precisely the complete vary of the poisons is within the species hasn’t been identified. So we used DNA sequence information, and we found that there are much more toxins within the loss of life cap than anybody had beforehand suspected.
SIMON: Demise caps are spreading?
PRINGLE: Yeah. After we take into consideration conservation biology, we frequently take into consideration the crops that we care about, or particularly the animals that we care about. However most biodiversity on Earth is not plant or animal. It belongs to different kingdoms, a few of which we’ve not even actually outlined very effectively. And the loss of life cap – after I first began working with it, I am unsure I cared an excessive amount of that it was toxic. It is intriguing as a result of it is from one place, and it is spreading in one other place. And invasive mushrooms are simply one thing we do not know quite a bit about.
SIMON: It is spreading in California?
PRINGLE: Yeah. It is spreading significantly in California. Different locations as effectively, however actually a sizzling spot for the place the loss of life caps are is in Northern California, across the San Francisco Bay Space.
SIMON: Why? Do we all know?
PRINGLE: Effectively, it should be one thing about having appropriate bushes that it could actually affiliate with, and it should be one thing in regards to the necessities that it wants as an organism to develop. There’s a number of concepts about why invasive species are invasive. That literature is de facto targeted on crops and animals. A number of the identical issues is perhaps true, however among the identical issues may not be true. That is one of many causes that toxins truly – finally, I discover them so fascinating, is that the toxins could also be in some way a key to how the loss of life cap is spreading and is so plentiful now in California. It is, on the whole, way more plentiful in California than it’s in its native habitats.
SIMON: And I’ve to ask – recognizing this can be a household present and now we have to watch out, how do loss of life cap mushrooms reproduce?
PRINGLE: Effectively, the standard, I suppose, manner {that a} mushroom reproduces is that two our bodies fuse. After these two our bodies fuse, they develop for some time, for some period of time, after which a mushroom is made out of that fused physique. However in California, the loss of life caps appear to have the ability to make mushrooms with out fusing. In different phrases, a person physique can simply make mushrooms by itself.
SIMON: I perceive your fascination now. What can we be taught in regards to the biodiversity of our world by having a look at loss of life caps?
PRINGLE: I feel the profound lesson that I stroll away with is how a lot is altering that we aren’t noticing. I typically really feel like my job is to bear witness to the modifications which might be occurring on the earth. And I try this by way of this actually painstaking, cautious examine of 1 species, nevertheless it’s only one species. And the identical dynamics that we’re watching with the loss of life cap are probably taking part in out with a whole lot of different mushrooms, however there is not anybody round who occurs to be fortunate sufficient to have the time and area to look at it occur.
SIMON: Anne Pringle, mycologist on the College of Wisconsin at Madison. Thanks a lot for being with us.
PRINGLE: Thanks.
