AI-generated description

Chlorophyllum hortense is a species of mushroom that belongs to the family Agaricaceae. It is characterized by its greenish-blue gills and spores, and a cap that ranges from grayish-brown to yellowish-brown in color. In East and Central Texas, Chlorophyllum hortense has been found growing in lawns, meadows, and along roadsides, typically in areas with rich soil and abundant moisture. It often fruits in the spring and summer months, particularly after heavy rainfall. The species is considered edible, but caution is advised due to potential confusion with lookalike species that may be toxic.
