Not Imleria badia. I like the Auroboletus mirabilis suggestion.

These look like a species of Armillaria to me.

Possibly Blewits (Lepista nuda) or maybe a related species of Lepista. But, there's nit enough info here to confidently propose an ID. Only eat mushrooms for which you are certain of the (edible) species ID.

There may be more than one species seen here. None look like Death Cap (Amanita phalloides). Some species of Agaricus are toxic (but not deadly so).

Amanita muscaria var. guessowii. The fall version often features the thick universal veil that causes the buttons to be white.

I'd say this is either Pholiota aurivella or P. limonella.

Undersides of the caps? Stems with rings or not? Spore print color?

Grifola frondosa; aka. Hen of the Woods, Maitake, Sheep's Head, Ram's Head. Looks like this one is somewhat past prime.

Is the cap viscid/sticky? If so, is the stalk also viscid? I agree this is a species of either Cortinarius or one of the other related genera of family Cortinariaceae. The taxonomy of the Cortinariaceae is a recent development.

Laetiporus species (Chicken Mushrooms) are prized by some collectors, others find them okay but not choice. Some people are allergic to Laetiporus. Like ZUnit said, this looks like an old one. They get kinda woody when post-mature.

Species of genus Leccinum section Scabra. These types have caps that lack reddish/orangish pigment. Filed guides typically conflate these species under the heading Leccinum scabrum.

Amanita crocea is similar but with the stipe surface decorated with patterned brownish fibers. I think this one is either Amanita fulva (or some closely related species).

Spore print color?

Xerula is the old genus for species now housed in Hymenopellis/Oudemansiella.

Yes, I think this is one of the species of "rooters" formerly housed in genus Xerula. Currently these are considered to be species of genus Oudemansiella or Hymenopellis (depending upon which mycologist you ask). Years back they were housed in genus Collybia, and for this reason one common name is "rooting Collybia." The one seen here may be this species https://www.mushroomexpert.com/hymenopellis_sinapicolor.html or https://www.mycoquebec.org/bas.php?trie=H&l=l&nom=Hymenopellis rubrobrunnescens / Collybie brunissante&tag=Hymenopellis rubrobrunnescens&gro=30. The brown stain on the stipe suggests the latter.

Species of Cortinarius. Some are known to be toxic; difficult to ID to species.

In my experience I believe I have seen examples of mushrooms representing section Arvenses with gills slightly pink-tinged (light brown just before becoming darker). Very young Horse Mushrooms have gills that are very pale gray, almost white. For the A. campestris types the gills are pink at first.

Maybe Boletus variipes? The combination of greenish pores/tubes, reticulate stipe, and non-bitter non-staining flesh suggests this. Type(s) of tree(s) in the habitat?

Some sort of polypore. Is the flesh fairly soft/flexible? Maybe a species of Ischnoderma.

Maybe a species of Ischnoderma. Looks like they're growing from wood.

On my property there is an area of about three square meters where I have found A. minutula, A. limbatula, and the provisionally named A. cyclops. They represent three different sections of genus Amanita; sections Amanita, Roanokenses, and Vaginatae respectively. These mycorrhizal species all seem to be associated with the same two 6 meter tall oaks.

Hello everyone at wmh.org. I've been really busy helping to make collections for the Continental Fall MycoBlitz. Be back here soon!

I once found what I IDed as an "aborted" version of Clitocybe robusta https://mushroomobserver.org/34972?q=1pECb . They did resemble the aborted Armillaria fruit bodies produced when those species are parasitized by Entoloma abortivum. But, I don't think this was due to an interaction with E. abortivum. The abnormal C. robusta are sort of a mystery. I shoudl ahve sectioned one of them to compare with the appearance inside a "Shrimp of the Woods." But, my guess is that the Cliticybe would lack the pinkish-brown staining often seen inside a "shrimp" and also on the interior of an Armillaria fruit body. My understanding is that E. abortivum only infests species of Armillaria.

When harvesting an Amanita for study, it is especially important to extract the entire fruit body from the substrate. features seen on the stipe base are important. We may eliminate parcivolvata, because this species has no partial veil. The cap color is more completely deeper red and the marginal striations less prominent that I'd expect for frostiana. According to amanitaceae.org he species subfrostiana is known only from China. So, I think neither of these is likely here. A. muscaria is known to occur in the UK. Here in North America we have a reddish variety of flavoconia (A. flavoconia var. inquinata). The description of the European A. erythrocephala is similar. http://www.amanitaceae.org/?genus+Amanita#letter_SP-

Rub one of the fronds and then check in 20 minutes to see if it has darkened. I think this may be Meripilus sumstinei (aka. Black-staining Polypore).
