Different stem, different flesh, different gills. OK?
I’d like some more info from Micah, about taste, smell, habitat and whatever can be provided..

Photos fuzzy…

Yeah, people need to stop holding up the mushrooms, just lay them down on some surface. When you hold them up, the auto-focus of the camera just locks in on the background, and you get fuzzy mushrooms.

I think Calocybe would be a stretch here, and might was well go with more common ideas. I like the Leucopaxilus, or these could be Rhodocollybia. But this is a lot of guessing for such fuzzy photos…

Whatever this is..

I don’t think the photos need to be as fuzzy as they are. The floor is sharper than the mushroom. If you don’t have a proper camera and are taking pictures with a mobile phone, check first if you have a macro option and use that. If not, use a longer distance to the object – and maybe the zoom, if there is any.
Anyway, the pictures seem to be taken closer than the camera can manage.

does also fit these photos and spore print. But these also tend to first appear later in the season (August… as do Tricholomas and Lepistas).

Of course there is not really enough information here to submit any type of serious species ID. My “Russula” guess has much to do with: 1. a wide variety of Russulas tend to appear here in the northeastern USA at this time of year, 2. I have lately seen a few Russulas that appear quite similar to the ones in these photos.

Tomorrow I’ll be in a place where I saw some of the Russulas. I’ll get some photos and post them in a few days.

quite foolish by me …

to name Rhodocybe and white spore print in the same sentence …. Of course it is in no way a Rhodocybe with this spore colour.
What concerns Lepista, there are several species with only cream coloured spore print, e.g. L. irina or L. nebularis.
Another possibility would also be Leucopaxillus.

I did not say that Russula is impossible, not at all. But just the habit of the fungus and the crowded gills don’t gives me the air of a Russula. But of course you have other secies in America then I have in Europe ….

gambosa is a white spored springtime mushroom, and the photos do look like this species. So it must be counted as a possibility. But, C. gambosa is rare to infrequent in North America (as I understand it). A few years back there was a discussion at Mushroom Expert about this mushroom occurring in the USA. I think there was one person who new of one instance of it’s having been found on this continent. Also, C. gambosa is typically reported (in the European reports) as an early spring mushroom. Actually, I think Calocybe perisicolor is a possibility for this one.

It is my understanding that Rhodocybe species do not have white spore prints. The prints are typically pinkish or brownish. If there is a Rhodocybe species with white print, please post the species name.

Finding a Lepista in the northeastern USA during late spring or very early summer would be a very interesting find. These types usually do not appear until the latter part of August and are most common in the autumn. The light pink to fleshy print color may appear to be white when viewed against a black or dark background. So, based upon the available info, we cannot completely rule out “Lepista.” But it would seem to an unlikely occurrence at this time of year.

I still think “Russula.” R. compacta (for instance) has gills that are fairly crowded.

in my opinion this could as well be

Calocybe gambosa or a Lepista or a Rhodocybe or a Tricholoma or anything else what has gills and white spores.
For Russula the cut seems to be too even and the gills too crowded

rules out Agaricus. I don’t see a ring on the stalk, either. Pics are a bit fuzzy, but the overall appearance points toward Russula. One indication of Russula is often observed by seeing if the stalk breaks like a piece of chalk. Lately I’ve been seeing some Russulas here in PA which have mottled lightly colored caps. Russulas are difficult to ID to species, and application of chemicals if often required. As I understand it, many Russula species have not yet even been assigned Latin names.
