Dark splotches/ streaks on stems, are they contaminated?
    #6698899 - 03/22/07 11:00 AM (16 years, 11 months ago)

If a mushroom looks relatively healthy, but has dark splotches or streaks along its stem, is it contaminated?

Thanks,
SN03

They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.

The cap is a bulb shape and I cannot tell if the veil broke, but there is a tiny dark primodia below it that has the same splotch as well...so I'm guessing they're not spores.

I'm just not sure,

just a curious question, do they look like water stains? I've seen that on mine after they caught an errant water drop or two during their fruiting process.

If that were the case, does that mean it's no good? Should the cake be removed?

Thanks,

Water stains? I always spray a fine mist directly on em, but sometimes it'll come out a little rough. Are you suggesting they may just be a little bruised from the water?

Thanks,

my friend's brf cakes had it. it is due to high temperature (30C) and bad FAE. it isn't dangerous to you. you can eat shrooms with verticillium but the disease stops the shrooms to grom and they mutate. freaky shit. the caps will get black & dark sports. the stems will look like they are splitting: green streaks.
