I noticed the red of the Partridge Berries first then the shape and color of the mushrooms as we walked the Eagle Lake Trail at Acadia N.P.
Tricholoma equestre–aka-Tricholoma flavovirens-aka-Man on Horseback. The ID is via iNaturalist and of course the images they show are of a fresh mushroom so iffy, I guess. And, of course, without a spore print certainty is a challenge.
Although obviously past its prime, I like the shape and color of the mushroom with its berry bonnet. I read that it was formerly considered edible but is hazardous to eat now.

Very nice mushroom. Strange that he went from etible to non-etible.

Thanks, Rudi. I don’t know what circumstances there were. Only some reports of poisoning where not for others.

Do the harmful effects of this mushroom not manifest till much later, so that people wouldn’t have connected the ill effects to the eating?

I am not sure. I have read that it is considered edible but there also have been reports of poisoning in Europe. Maybe they had spoiled or some people just have bad reactions to them.

And maybe there was a slug in those that caused poisoning ☠️

The common name perplexed me. I found that one reason it might have been given the name ‘man on horseback’ was an assumed resemblance to a saddle. In Europe, it’s also been called the ‘yellow knight.’
I thought this was interesting: “Although reported in some field guides to be edible and very tasty, and indeed having been sold as such throughout much of mainland Europe until recently, the Yellow Knight is now known to be toxic and should definitely not be collected for the pot. The poisonous chemicals in these fungi have not been definitely isolated, but several cases of painful muscle damage have been attributed to eating these chunky fungi.”

I saw that common name also Your link is part of the reason I do not forage. Aside from easily mistaking an inedible for a safe one, not everything is known about all. I do enjoy wild mushrooms but rely on the growers who supply them rather than my own hapless identifying skills.

As others have said, it’s fascinating the change from edible to non-edible. We continue to learn about nature. It also had me wondering if it might be similar to blowfish (fugu), that if not prepared just right is poisonous. I do like the red berries in the composition, nicely seen.

It could be like blowfish, at least in some cases. I’ve read that certain poisonous Amanitas can be consumed after multiple boilings but that seems like too much trouble and what if it needed one more? Thanks, Todd. I was pleased that the berries were part of this mini scene..

Very nice, and who cares if it’s getting long in the tooth as long as we’re not going to eat it. I often read conflicting information about mushroom edibility so I’m really not surprised that this species used to be considered edible but isn’t now. Beautiful colors!

Thanks, Lynn.
I guess it takes a few fatalities to get some on the radar. It doesn’t sound like these cause death, just severe cramps which could possibly make someone wish they were dead. 🙂
