Button, crimini, and portobello are all the same mushroom

posted by Jason Kottke   Mar 15, 2016

The common button or white mushroom, the crimini or brown mushroom, and the portobello mushroom are all the same species of mushroom.

Agaricus bisporus has increased in popularity in North America with the introduction of two brown strains, Portabella (sometimes also spelled portobello, portabello, or portobella) and Crimini. The three mushrooms you see to the right are all actually the same species. Portabella is a marketing name the mushroom industry came up with for more flavorful brown strains of Agaricus bisporus that are allowed to open to expose the mature gills with brown spores; crimini is actually the same brown strain that is not allowed to open before it is harvested.

See also the magical Brassica oleracea plant (cabbage, kale, broccoli, brussels sprouts, kohlrabi, collard greens, and cauliflower are all the same species of plant). (via @dunstan)
