I was chopping up some portabella mushrooms (purchased at Costco) for a stir fry and noticed that the flesh of some of the mushrooms turned a dark brown (left):

It has a slightly rougher texture, and smells stronger than the whiter mushrooms. Never seen a mushroom like this before, is it safe to eat?

Did you buy the mushrooms from a (reputable) seller or did you pick them yourself? – bob1 Oct 12 '21 at 22:47

@bob1 I bought them from Costco – Android Won Kenobi Oct 12 '21 at 22:50
Also, all the mushrooms in the image are from the same package. – Android Won Kenobi Oct 12 '21 at 22:51

Thanks - that makes it easier, it means they are actually edible mushrooms, something that is not always guaranteed for mushroom problems on here. – bob1 Oct 12 '21 at 23:53
See https://en.wikipedia.org/wiki/Agaricus_bisporus -- nothing unusual, the white ones are immature. Nothing wrong those unless mishandled like any other mushrooms. – Dan Mašek Oct 13 '21 at 02:01

@bob1 Or, at least, it means that if he eats them and gets mushroom poisoning, he can sue CostCo for selling him poisonous mushrooms. – nick012000 Oct 13 '21 at 06:13

@DanMašek I was talking about the one on the _left_ with the dark colored flesh. It doesn't look like any other portabella that I handled before. All the pictures that I look at show white flesh, like the one on the _right_. – Android Won Kenobi Oct 13 '21 at 12:48
Well... Are these okay to eat? – Android Won Kenobi Oct 20 '21 at 18:44
@AndroidWonKenobi are they slimy and / or smell fishy or sour? – Juliana Karasawa Souza Oct 22 '21 at 12:32
They smell stronger/woodier than the other mushrooms, and they feel rough. – Android Won Kenobi Oct 22 '21 at 17:48
Looks like oxidation, perhaps some mushroom pests like maggots or slugs ate into the cap and caused the interior to oxidate? – Diu.Lei Oct 19 '22 at 19:41
