turns yellow with application of KOH. But this obs looks much more like Agaricus arvensis to me. A. arvensis also turns yellow with KOH. Young specimens of A. arvensis sometimes show very pale gills…. just a tad off white.

Are you sure it wasn’t an agaricus at an early (white gill) state?

The yellowing flesh and almond odour seem like agaricus hallmarks.

I’m not sure how the nearly nonexistent volva plays in there, perhaps part of an expanding stem?
