Second ones are definitely oysters.
thanx for confirmation. i was 99% sure about it too. (the trunk was spruce btw). the sad thing -- they stopped growing and started aging on the very 2nd day! so, no big harvest, no fried potatoes with shroomssss :((((

Yeah you have to bring the spray bottle to feed them before they dry up. Sadly it hasn't rained here in a while too and the oysters have dried up.
I did it, dripped that stump with water. didnt help much..
