Help for the identification of gilled mushrooms

question 20: Flesh changing colour when cut and exposed to air

Some compounds contained in mushrooms react to the oxygen of the air and induce a colour change of the flesh as soon as it is exposed to air. To highlight this property, we just have to cut the mushroom into two pieces, look for a potential colour change of the flesh immediately when it is cut, and check again after a few minutes upon exposure to air.
if we don't see any colour change at all, we must also indicate it in this section. Make sure that you let a few minutes go by before checking the colour again and answering this section of the questionnaire.

Examples:



In this example, the flesh is white when being cut...     ... but turns pink after about a minute of exposure to air. In this case, select then "yes".



The flesh was white, but turned greyish upon exposure to air. Select then "yes" in this case.     The flesh was yellowish, but turned brown upon exposure to air. Select then "yes" in this case.     The flesh was white, and is unchanging upon exposure to air, even after a few minutes. Select then "no" dans ce cas     The flesh was white, and turned clearly reddish-brown upon exposure to air. Select then "yes" in this case.
