Need to see undersides and entire stalks.

Desarmillaria caespitosa, the North American Ringless Honey Mushroom.

Looks like Desarmillaria ceaspitosa, aka. Ringless Honey Mushroom. These are edible for most people, but some folks are allergic to Desarmillaria and/or the similar Armillaria species. I always recommend par-boiling these types before preparing as part of a meal, because I think this reduces the amount of the substance that causes bad reactions for some people. I suggest trying a small well-cooked amount. As for drying. It's best to use a dehydrator. But, air-drying for a few days followed by 20-30 minutes inside a 180F oven(open the door after 10 minutes works. String them up in a south-facing window that gets plenty of sun. However, in a very humid environment, this does not work very well. Insects that may ruin the finished product are likely inside the mushrooms to begin with. So, vertically sectioning each one will allow you to discard any that show signs of insects (ie. damage, tunnels, etc). My favorite way to preserve Armillaria/Desarmillaria is to par-boil, rinse in cold water, and freeze in packs of about 1 cup each. Wrap in plastic wrap while still wet and then foil. Inside a non-frost-free freezer they last for years. Inside a conventional refrigerator freezer (frost free) they should be used within around 8 months.

Best to start a new thread/discussion for a mushroom not being discussed.

Of the three Rubroboletus species documented on California Fungi Species Index... R. eastwoodiae has a pale cap and a strongly bulbous stipe base. R. pulcherrimus has a reticulate stipe surface. R. haematinus is said to associate with fir. The boletes seen in the photos posted here look to be kinda old. So, matching up morphology may be challenging. I don't know the west coast boletes first-hand.

The gill edges appear to be serrated. This points toward Lentinellus. Compare with https://www.mushroomexpert.com/lentinellus_ursinus.html .

I think the mushrooms seen in the first photo are a species of Tricholomopsis. If correct, spore print will be white.

Color seems off for P. oveideocystidiata. I don't see any blue or greenish staining. Spore print color?

The photos don't show details very well. Black (or at least very dark) spore print suggests Hypholoma, Leratiomyces, or possibly Psathyrella. Presumably, not edible... as should be the case with any unidentified (or poorly identified) mushroom.

Looks like Trametes versiclor (Turkey Tail) and a species of Hypholoma, possibly H. lateritium (Brick Tops).

Looks like an old fruit body of Fomes fomentarius.

The top photos show what looks like the polypore Fomes fomentarius. Also, Ganoderma applanatum is a possibility. Type of wood?

I see conifer needles in the photo. If the fungus is growing on wood of a conifer, then Dacrymyces is likely. "Witch's Butter" is a name given to species of Tremella, usually T. mesenterica. Tremella generally grows on wood of broadleaf/hardwood trees. Microscopy (spore morphology) would settle Dacrymyces vs. Tremella.

Are the gills attached to the stipe, or free of the stipe?

First two photos show Trametes betulina, the "Gilled Polypore."

Looking again... I think the variability in the darkness of the gills is the result of photographing the mushrooms in different ambient light.

Genus Pholiota features variable morphology; some are scaly, some are not. Pholiota looks like a good suggestion to me. Also, compare with Flammula alnicola. Honey Mushrooms (Armillaria) have starkly white spore print.

I think the mushrooms seen in the first few photos are a species of Armillaria, but not A. gallica. The latter has a stringy fleeting partial veil.

Need to see the base of the stalk for the Amanita. I think the bolete is Aureoboletus roxanae.

If it's a Russula mushroom (I think so) then you should be able to break the stem like apiece of chalk. Tricholoma mushrooms have stems that are mire fibrous. Some species of Russula from subsection Nigricantes are suspected to be toxic.

These look like Hypholoma lateritium (Brick caps). Seeing more detail would help. Spore print color is dark purplish-gray for H. lateritium.

Tapinella atrotomentosa.

The third photo may show Turkey tail (Trametes versicolor). Do the undersides feature very small pores?

The bottom photos may show a species of Armillaria. But, the photos showing mushrooms with light brown gills are likely something else.

The yellow mushroom seen in the uppermost photo is a species of Pholiota, probably either P. aurivella or P. limonella. Some people are sickened by eating these tyoes, although they are not considered to be dangerously toxic. The mushrooms called "opiata" in Russia are species of Armillaria (not Lepiota). I doubt there's any validity to the claim that mushroom toxins may be detected with a fluorescent flashlight.
