I’ve never seen these fungi before. They look like large garlic cloves squashed together. Many grown together with mushroom clusters. I am uncertain . They only growers on the floor of the forest.
carpophoroids should be referred to as Aborted Armillarias. https://botit.botany.wisc.edu/toms_fungi/sep2006.html
So according to our data, the field guides are mistaken on this point-- Entoloma should be considered a pathogen of Armillaria. We recommend the name "Aborting Entoloma" for the common name. Moreover, the carpophoroids should be referred to as Aborted Armillarias.
No cap formed at all. What is this? Entoloma abortivum seems the closest. It always seems to be growing near to mushrooms. https://botit.botany.wisc.edu/toms_fungi/sep2006.html

Not velvet but the closest I could find. Does turn blue with air contact. I believe it might be a Porphyrellus pseudoscaber. It is completely dark brown.
Tylopilus alboater looks the closest in appearance color and shape.
It is probably not Stropharia rugosoannulata or a Lepiota cristata but it is as close as I can find. The body gills and stem are white and the cap
deeply cracked. It showed no signs of growing in clusters. There several growing sporadically. No ring below the cap.
What about the agaricus bernardi? It was not near a salt marsh.
I’m not sure it’s a brittlegills because I cannot find a matching photo.
