SBBM.
Great post, jjeroche, and yes, I agree with all your thoughts.
Decades ago, I attended a four-day course on wild mushrooms.
The leader was an esteemed mycologist whose name I've forgotten and to whom the stomach contents from victims of fungi poisoning were sent for identification from all over the world — he had long, pointy ears and the quizzical face of a gnome. When I first saw Yoda the following year, I thought that's the mushroom man!
He took us out to forage and cooked us a fabulous meal consisting of an appetizer, main dish, and dessert using only eggs, pasta, nuts, honey, wine, herbs, spices, and countless varieties of mushrooms.
He repeatedly warned us that every edible mushroom has an almost identical toxic counterpart, indistinguishable by most people. He showed us some examples in the forest to drive home his message.
He discouraged us from foraging, saying that to avoid being poisoned, one had to be either professionally trained in mushroom identification or very lucky.
For this reason, I've never again picked wild mushrooms.
And for this reason, if the evidence proves that EP's guests died from ingesting toxic mushrooms, I can't stand with those who already appear confident she poisoned them intentionally.
