Cremini, also known as crimini mushrooms, are simply a different strain than the white button. Developed by commercial growers, they are brown in color and have a slightly deeper taste. Growers also created the concept of portobello mushrooms to sell mature cremini.
Cremini mushrooms have a light to dark brown cap with a short white stem. Small brown gills are hidden beneath the cap. The flavor is mild and somewhat earthy with a meaty texture. The entire Cremini mushroom is edible, unlike the stem of the mature Portobello.
