Agaricus bisporus is the interesting name for this mushroom. Agaricus, cleverly, means gilled mushroom. In the early days of mycology, every gilled mushroom was placed in the genus Agaricus.

Now Agaricus is restricted to saprophytic mushrooms with a chocolate brown spore print and usually an annulus ring around the stalk. The epithet "bisporus" refers to the two-spored basidia lining the gills. You'll recall that most mushrooms have 4 basidiospores on each basidium, with each spore containing one of the 4 haploid products of meiosis.

These spores are shed separately and must find a mate in order to form mushrooms again see the page on Schizophylum commune for a good explanation of mating types in these so-called heterothallic fungi. Agaricus bisporus produces only two basidiospores on each basidium.

Each of the two spores contains two of the products of meiosis-- the consequence of this is that each spore already contains the nuclei needed for sexual reproduction and does not need to find a mate.

It has, in effect, already mated with itself! Such a system is called secondary homothallism. This ensures that every spore that lands on a suitable substrate is capable of forming mushrooms.

However the consequence of this mating system is that it is very difficult and tedious to do breeding work with Agaricus. An apparently older name for this mushroom is Agaricus brunnescens, referring to the oxidative "browning" reaction when the mushroom is bruised.

There is a movement underway to conserve the name Agaricus bisporus, so we will refer to it by that species name here.

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.

Per capita consumption of fresh Agaricus in the United States is about 2. Many people love to eat mushrooms in omelets, in stir-fry, on salads, and in soups.

Marinated and grilled portabella is a treat not to be missed. Mushrooms are an excellent low-calorie meat substitute with great nutritional value and lots of vitamins.The pinheads grow into full button sized mushrooms in another days. The environment parameters are maintained as above during entire period of cropping.

Temperature has influence on RH and CO 2 conc. and hence should be maintained/manipulated, keeping in mind its effect on other two factors.
