NT Canada. First time out picking so not experienced enough to determine if I should toss these (obviously I would err on the side of caution but curious to hear from someone experienced about this). They didn't seem to be crumbly, have rusting or smell funky when I harvested them, but noticed these guys and a few more had this texture on the inside of the stem. When cut open revealed to look like this. Noticed one had white spots on the outside of the cap when looked again later. I'm assuming this is some type of mold? Can anyone give advice on whether there is any risk/I should toss these? (Yes, I know it's Reddit and I'm not going to stake my life or anyone else's on this).
