Division I DEFINITION OF PRODUCE

This standard applies to the Carpophores (fruiting bodies) of strains grown from the genus Agaricus (syn. Psalliota), to be supplied fresh to the consumer, mushrooms for industrial processing being excluded.

Mushrooms are classified into the following commercial types, whereas these first of all are classified into two groups:

• uncut mushrooms, which have the lower part of the stalk uncut,

• cut mushrooms, which have the lower part of the stalk cut.

In both groups a distinction is made between successive stages of development:

• closed mushrooms (or equivalent denomination), i.e. mushrooms with the cap completely closed,

• veiled mushrooms, i.e. mushrooms the cap of which is connected to the stalk by the veil,

• open mushrooms, i.e. mushrooms with an open cap (open cap or flat; a slight downturn of the edges of the cap is required),

• flat mushrooms, i.e. mushrooms which are fully open (but the edges of the cap are neither too cupped nor inverted).

Mushrooms are further classified into two colour groups:

• ‘white’,

• ‘brown’ or ‘chestnut’.
