Rainy: October is prime mushrooming season in Washington, especially after a rain season, and it can definitely be rewarding finding your own chanterelles rather than paying 20$ a pound for them.
Any wild mushrooms you find and confidently identify should definitely be cleaned thoroughly. I recommend lightly boiling the russulas and lobster mushrooms before using as well, though this step is not totally necessary, the ones we found had a fair amount of dirt on them. Chanterelles should be lightly sauteed in (vegan) butter, the lobster mushrooms in olive oil. The A. bisporus is just a common/cremini/button mushroom and can be prepared in any number of ways. Un-parasitised R. brevipes are edible, but have a pretty bland flavor so I would recommend adding them into things rather than eating them fairly plain like the Chanterelles.
I wanted to make soup so I used all but the chanterelles in that, especially the un-parasitised russulas, I used an organic mushroom broth base and also added onions, chickpeas, potatoes, canned tomatoes, and field roast to make it more hearty. I seasoned it with rosemary and basil though that is of course up to subjective taste. Soup making is an unrefined art after all.

A serious note on mushroom hunting: I have a reasonable amount of experience with identifying these species but I also double checked individuals with my biology professor. It's really important to do your research, and double check with an expert (not just google images) if you're inexperienced. It can be exciting and easy to jump to conclusions when identifying specimens. Toxicity varies and you could just end up with an upset stomach, but lethal species do exist and can resemble edible species. Long story short: be very careful and triple check everything.
