They are more mature than white button mushrooms
Baby bella mushrooms are also known as cremini mushrooms. They are the same variety as white button mushrooms but are harvested at a more mature stage, resulting in a more developed flavour and firmer texture. They are also the same variety as Italian portobello (or portabella) mushrooms but are picked at a younger stage. Baby bella, white button, and portobello mushrooms are all different maturations of the agaricus bisporus fungus species.
White button mushrooms, also known as immature mushrooms, are the youngest, most immature form of the white strain of Agaricus bisporus. They were developed in the early 1920s by Pennsylvania mushroom farmer Louis Ferdinand Lambert, specifically for their white colour. The common white mushroom has a smooth, white cap that can range in size from 1/2 inch to 2 inches in diameter. Under the cap, there is a closed veil covering immature gills. They have a mild, slightly earthy flavour and a delicate texture.
Baby bella mushrooms, on the other hand, are picked when they are more mature, resulting in a more pronounced earthy flavour and firmer texture. They are small and brown-capped, with a deep and savoury flavour. Their rounded caps should curl underneath, touching or almost touching the stem, covering the gills. When the gills start to show, it means the mushroom is no longer fresh, but it is still edible.
Portobello mushrooms, also known as portobellas, are the fully mature versions of the brown strain of Agaricus bisporus. They are the largest variety of cultivated mushroom and can also be marketed as Giant Cremini or Ports. Portobellos have much larger caps than baby bellas, measuring 4 to 6 inches in diameter. The caps are brown with slight scales, and underneath, there is an open veil revealing dark brown gills.

Fresh baby bellas should be dry, firm and smooth
Fresh baby bella mushrooms, also known as cremini mushrooms, are picked when they are more mature than white button mushrooms, resulting in a firmer texture and a more developed, earthy flavor. They are smooth, brown-capped fungi with a deep and savory taste.
When buying or picking baby bella mushrooms, it is important to ensure they are fresh. Fresh baby bella mushrooms should be dry, firm, and smooth. They should not be slimy, wrinkled, or soft. If the mushrooms are dry, it is a sign that they are still edible, but they should be used as soon as possible as they are on their last legs. If the mushrooms have started to develop dry patches and don't look as plump as they used to, it is a sign that they are about to go bad.
To ensure baby bella mushrooms stay fresh for as long as possible, proper storage is essential. They should be stored in a breathable container, such as a paper bag, to prevent the buildup of moisture and keep them from spoiling. It is best to avoid storing them in airtight containers or plastic bags as the lack of airflow will cause rapid spoilage. A paper towel-lined paper bag can be particularly effective in cutting down on extra moisture.
Baby bella mushrooms should also be stored in the refrigerator, ideally in the crisper drawer, and used within four to seven days. Sliced mushrooms will spoil more quickly than whole mushrooms, so it is recommended to buy whole mushrooms and slice them yourself. It is also important to note that mushrooms should be as dry as possible before cooking.

Bad baby bellas are slimy, wrinkled, discoloured and smelly
Baby bella mushrooms are a type of brown-capped Agaricus bisporus fungus. They are the same variety as white button mushrooms but are harvested when more mature, resulting in a firmer texture and a more developed, earthy flavour. They are also known as cremini mushrooms and are the younger version of portobello mushrooms.
Like all mushrooms, baby bellas can go bad. Bad baby bellas are slimy, wrinkled, discoloured, and smelly. If your baby bella mushrooms have any of these characteristics, they are no longer safe to eat. Slime means that bacteria are starting to grow on the mushrooms, and they could contain harmful bacteria that can cause food poisoning or botulism. Bad mushrooms will also have lost their flavour and nutritional volume.
To prevent baby bella mushrooms from going bad, it is important to store them correctly. They should be stored in the fridge and used within four days. They should be kept in a breathable container, such as a paper bag, to prevent the buildup of moisture, which can lead to spoilage. Avoid storing them in an airtight container or plastic bag.
If you notice that your baby bella mushrooms are starting to wrinkle or shrivel, use them as soon as possible. You can rehydrate them, but if they are discoloured, slimy, or smelly, throw them out. Fresh mushrooms should be dry, firm, and smooth, with a pleasantly earthy slightly sweet smell.
To cook with baby bella mushrooms, always ensure they are as dry as possible before cooking. Begin by cooking the mushrooms over medium-high heat in a small amount of oil. Avoid overcrowding the pan so that moisture can escape. Add salt and aromatics, such as thyme and garlic, after the mushrooms have released most of their water. Finish with butter or ghee towards the end of the cooking process.
