remember there are thousands of shrooms...morels which have nooks and crannies for critters, polypores....hen of the woods/chicken of the woods have fronds going everywhich way, puffballs which are just big balls of shroom no nooks no crannies, there are wild there are cultivated......
Boletes, shaggy manes, shiitakes, all are different....gills, no gills, etc...
I can tell you most mycofogist will not wash in the woods, they cut the stems so that there is no dirt in the basket, if the shrooms are prolific they'll not even pick dirty ones. But then it's not unusual to have alittle critter protein in a large batch of cooking shrooms. It's a very forager mentality.
I've seen nice restaurants 3x wash especially morels....salt water soak then 2 plain. Shroomers would tell you that you've lost alot of flavor. Chef's might say they don't want worms or bugs in their guests food.
cooking with all your senses.....
