I believe it is phalloides. Large smooth green-brown cap. Shows up in multiple locations in the yard, the first ones just beginning to emerge.
Greetings @Nik, For ID, suggest digging one out, digging down underneath it to be able to remove the entire base. If there is one that is a bit more opened up that would be useful too. It doesn't look like A. phalloides at this point - more info would be helpful.
@Nik, good afternoon Nik, if it is Amanita phalloides, then this should not be consumed. You probably already know this, but IMO it does not hurt to reafirm the warnings. I have seen the consequences too many times in the past of what this fungi can do. Not pretty and fatal !! I am sure that @Frog can ID this for you looking at the postings. I would not dare to try.
Thank you for the great diagnostic shots @Nik It doesn't look like one of the Amanitas of my region, so will take a look at the NE of NA Amanita options
... Overall colour, veil, base, volva and cap/stipe ratio characters look like Amanita bisporigera and Amanita virosa. Both are listed as common in your region, so seem like strong possibles ... but these are not species with which I am conversant. Some interesting characters that may also be of use are; the striate cap margin, the swollen but not large base, and the large central veil remnant on cap in one photo. Here is an Amanita resource for your area: Keep in mind that photos can be limiting - some species are quite variable in some respects. US - Northeast - Amanitaceae.org - Taxonomy and Morphology of Amanita and Limacella
Perhaps fungi are hoping to entertain us with these ID challenges ... The wonderful thing about mycology is that there is always more to learn, one never reaches the end, there is absolutely no chance of being bored :-) :-) :-) Your mushroom differs from A. virginiana in enough key character respects that I don't think that is your critter. The description of A. bisporigera group is closer, more characters are a match.
