Agreed Dave, even before I read your response I was thinking Russula. Which Russula is a much more difficult question.

Possibly Cerioporus squamosus (Dryads Saddle) growing out of that fissure?

Yes, looks like an old Lactarius indigo. Does it exude any milk when cut (try slicing the gills)? L. indigo is unique in having blue milk. It might not produce any milk because it's old.

There's also lots of mushrooms that sometimes will grow in a half circular pattern and people will attribute it to being a "fairy ring", despite it just being a coincidence that they grew like that. I often see A. muscaria pictures that are kind of a half ring, but they're mycorrhizal and don't really fit. That being said, it doesn't hurt anyone, so I'm happy enough if people are excited by finding a bunch of A. muscaria and thinking they kind of, but not really, form a ring. Whatever it takes to get people interested in mushrooms! Haha.

Fomitopsis butulina. Birch Polypore. It's an annual fungus, and these are old ones that have survived the winter and will soon rot and fall from the tree. They actually last a long time, well into the next season.

They look like Leucocoprinus. Maybe compare them to Leucocoprinus cepistipes, which is known to occur in Queensland. I'm not sure it grows on dung though (grows in rich soils and on mulch). Actually, I'm not sure any species of Leucocoprinus grows on dung. There's mostly a tropical genus however, so very not in my wheelhouse.

Dave W, I think Marasmius nigrodiscus is a very good guess. Good eye. I'm not familiar with it and it doesn't appear to occur this far north.

SidneyM, you haven't missed the season. But the season is right now. If you look on iNaturalist, you can see people reporting observations from you area. Get out there! I hope you find one, and let us know if you do. Good luck.

Sorry for the super late response, but yes, they certainly do grow on Oak. I find them more commonly on Maple and Beech, but there are a lot more Maple and Beech forests around here than Oak. This is in reference to Pleurotus ostreatus. Pleurotus populinus grows on Poplar. Pleurotus pulmonarius grows on all types of deciduous wood.

I could see how some of the larger ones (like in the last photo) could be mistaken for Woodear (Auricularia).

That's a tricky one. Based on these photos, I wouldn't think they are Cantharellus. The gills look way too developed. The fruity smell does seem to point towards chanterelles, however. The younger ones seem to have an in-rolled cap that is typical of H. aurantiaca. But it shouldn't have a fruity smell. I wish we could see the top-view of more than one specimen. I'm going to go with "I'm not sure".

Yeah, that's an Agaricus.

It's really hard to say without seeing the gills. But Paxillus involutus came to mind first for me (a close look alike of Tapinella; they used to be in the same genus). The striations on the margin are more typical of P. involutus. Unfortunately, Paxillus are very poisonous, sometimes deadly, for humans. However it might not affect dogs the same. Also, it might be something completely different because we can only see the cap. Hope your dog is doing ok.

I always find it hard to tell from a photo. In real life it's easy, but "pink" spore prints always look kind of brown to me when view on my mobile or laptop. So I hesitate to base too much on the colour in this case. Definitely not Lyophyllum though, which has a pure white spore colour. When they say it's pink, it's more of a salmon pink than a barbie pink. Entoloma s.l. has a deep pink (salmon) spore print, and Lepista species have a very light pinkish spore print, closer to white or creamy than salmon coloured. I'm guessing this is a more likely to be an Entoloma type species, based on the photo. That being said, it's hard to tell from a photo. A deeper/thicker spore print will naturally give a deeper colour, although the thickness of spore print is very hard to tell in a photo. etc.

Oh no. Not even remotely close to Cantharellus tubaeformis. Gymnopilus species is likely as others have suggested.

Agree that they look like Armillaria.

Imleria badia (Bay Bolete) is supposed to have flesh that can turn reddish or bluish a bit when cut. That's probably the reaction you're seeing if you were confidant with your ID.

They're in the genus Cortinarius. Note the weblike attachment between the cap and the stem (which is called a Cortina). I couldn't tell you the species though.

They're Leucoagaricus leucothites, aka White Dapperling. Keep in mind that while they're edible, they're very similar to the white deadly Amanitas, and definitely aren't recommended for eating. Also, you should be 100% of your ID before consuming a wild mushrooms, and you weren't 100% if you're asking here. I'm just mentioning this in case you look them up and read that they are edible (but without the precaution mentioned).

I agree that they don't look like M. oreades. The gills aren't enough well spaced and they lack the umbonate cap. I'm always hesitant to offer suggestions for Florida, as the fungal flora there is so different than what I'm familiar with.

I've always been curious to eat them. I don't mind a little bit of bitter, and enjoy tonic water and arugula for example. But these are way too bitter! I wonder if cooking them lessens the bitter taste.

The gleba of C. cyathifrormis would be purplish at this stage of maturity. Compare it instead to Calvatia craniiformis, which has a yellowish/olive, to brownish gleba when mature. Also, C. cyathiformis doesn't seem to be ever this small, while the range of sizes for C. craniiformis includes smaller fruiting bodies like the one you found. Although it's on the extreme small end of it's range. I wonder if there are any other small species that this could be?

I don't think so. C. torvus is distinguished by a partial veil that is borderline membraneous (rather than web-like as most Corts are). The specimen pictured seems to have a cortina that is very web-like, judging from the remnants on the stipe (edit: this means "stem") and the cap margin. Also, C. torvus is supposed to have very well spaced gills, which doesn't quite match. Another feature of C. torvus that you might check is the flesh is supposed to be whitish, but marbled with violet at the top of the stem. Do a cross section and check. There are a LOT of species in Cortinarius. I rarely try to ID them unless they appear unique in some way (which I always discover is actually not that unique after all, because there are just so damn many species), or unless I have a lot of time on my hands.

I've eaten it once, and don't have fond memories. Interestingly, it's listed as non edible on mycoquebec.org. Perhaps it's just a case of it being such a poor edible that they don't recommend it? I'm not sure, as they don't expound on it in the comments.
