There are a few other species that look like this

You need micro to make anything more than a ‘could be’ identification with these.

In Europe there is maybe 3 or more species that can look like this (See A. ochracea, A. vervacti & maybe A. arvalis), in CA there is at least 1-2 that can looks like this (One known only from an erroneously named spore photo and the other in the mountains), as for your area I’m not sure anyone knows the answer…

And here is the habitat description from FAN6 for European collections.

HABITAT & DISTR. — Solitary or in small groups, saprotrophic;
terrestrial on nutrient-rich, usually disturbed places in grassy roadside
verges, lawns, garden beds and grassy or open places in dunes. Very
common in most of the Netherlands, less common in the southeast.
May–June; occasionally till Nov. Widespread and common in Europe,

A. pediades can grow in cultivated ground

Both Arora and Lincoff say A. pediades grows also in wood mulch/chips, cultivated ground, manure and sand so the habitat seems right. Arora says: …“typified by yellowish cap, brown spores, absence of ring, small size”. It all seems to point to the A. pediades group.
