Mushrooms are small to medium in size with caps attached to short, truncated stems. The smooth white caps are rounded, firm, and spongy. When bruised, the white flesh will turn light pink and will then transform into brown. Underneath the unopened caps, there are many small, light brown gills that are hidden with a white veil and these gills produce dark brown spores. The short white stem is also edible, dense, thick, and smooth. When raw, mushrooms are mild with a crisp texture, and when cooked, they develop an earthy flavor with a tender, chewy texture. Mushrooms contain some antioxidants, potassium, selenium, amino acids, vitamin D, riboflavin, phosphorus, zinc, folate, and manganese.
