First time actually eating them, played it safe and boiled for 10 mins, cooked for 15. Really tasty but totally overdid it haha, no GI upset though. Had a bad time with Chlorophyllum brunneum once and didn't want a repeat.
Seem to be Armillaria sinapina, yellow veil remnants and thats what is most common in my area.
I'm surprised we got these, season started out good but now we are going on almost 2 months with no rain in my area.
