Reddish champignon is a forest mushroom of the order Agaricales. It, like many of its relatives, can be found in wooded and humid areas in the southern United States, from California to Florida; as well as in Europe, the UK and New Zealand. In Ukraine, the fungus grows in Polissya, in the Left-bank forest-steppe, in the Carpathians.

The fungus can be found from July to November in coniferous and mixed forests, meadows and pastures, in the steppe.

Information about edibility is conflicting. In most sources, the mushroom is indicated as conditionally edible (you need to boil for 10 minutes, drain the broth, then you can fry, boil, pickle). In one English-language source, it was written that the mushroom may be poisonous to some sensitive people, and it is better not to eat it.
