These look like frostbitten bonnets (Mycena, probably Mycena galericulata). I can see they grow in tufts, which some Mycenas do, and their gills are still sort of whitish (they'd be pure white if the fruitbodies were fresh and alive).
They contain some muscarine, so they'll give you sweating, teary eyes, cramps and diarrhea.
There's a very similar-looking genus of fungi with thin stems and conical caps called Conocybe, which grow in lawns and are the same pale yellowish-brown color as these. Those contain amatoxins and even a small handful can kill you if you mistake them for liberty caps. Liberty caps have purplish black gills and need to have vividly bluish-black stains on the stem to "work". However, I honestly fail to see the need to "augment" or "alter" the current reality any further
Stropharia ambigua. I've read they're pretty common along the Pacific Northwest. Some say they're marginally edible, but they probably taste like dirt or might give you a gastrointestinal upset.
Guessing winter chanterelle?
These are Clitocybe species. They are notoriously difficult to identify and many contain high levels of muscarine. Just leave all bleak thin funnel-shaped dingy-whitish-grayish fungi alone.
This one looks like oyster, but grows out of the ground
The same goes for any "oysters" that grow out of the ground, unless you can see clearly that they're growing from a chunk of wood or a dead root. Stay away from them.
I have no idea what that is. Possibly also a big Clitocybe species, or a Leucopaxillus, or an ugly instance of Melanoleuca verrucipes. Don't eat it.
These are dapperlings, probably from the Lepiota cristata (Stinking Dapperling) complex. A typical Lepiota is a slender whitish fungus with white gills, usually some sort of ring on the stem, and a reddish-brown scaly spot in the center of the cap. Many of these small Lepiotas are said to be anywhere from mildly to deadly poisonous.
I wouldn't buy lottery tickets if I were you.
Speaking of good field guides, Noah Siegel and Christian Schwarz, both very competent mycologists, published a beautiful book on fungi of coastal Northern California not long ago. Most of the species there should overlap with what you have in Washington.https://www.amazon.com/Mushrooms-Redwood-Coast-Comprehensive-California/dp/1607748177/
