If one takes 0,3x0.3m there are 50+ of them, next m repeat, ....Mainly beige, but seems they were brown at one point.
Edit: Agrocybe x ?

I’d overlooked these little ones...
To me, they resemble one of those Galerina species that grow in grass and/or moss; perhaps Galerina graminea (microscopic identification is necessary for these species).
The margin appears slightly striate to me (pictures in web show mostly obvious striation), no traces of a velum, and the surface of the cap is hygrophanous.
