Is a Gymnopilus beyond all shadow of a doubt. There are doubtless a number of Gymnopilus species in your area besides whatever gets called “subtropics” over there.

Agaricus have free lamellae and occur in soil.

Gymnopilius name proposal

The larger examples of the observed mushrooms were 100-150mm in diameter. Hemmes & Desjardin list a size of 30-50mm for Gymnopilius subtropicus. Spore deposits were brown → dark brown (as described for Agaricus) vs. bright rusty brown for Gymnopilius. Observed stems where white, not brown.

Any chance
