I've just read in another post about shrooms that have stripes (fairly wide not pin stripes) or one stripe of darker colored stalk running up them. Does anyone know what causes this or is it bad? or how to prevent it? is this the water logging and the transparency look that I have read about?

I have seen stripes on the stems of shrooms that were not waterlogged... And I have seen waterlogged shrooms that had no stripes... But generally it is considered a sign of overhydration.

For whatever that is worth...

I'm not sure what causes it, but whatever it is, it isn't harmful, and the shrooms are still edible. It could be a weak colony, it could be some kind of contam, or it could be too much water, or maybe some combination of these. I can't pin it down. Right now I have several cakes in the growing chamber, of the same syringe and the same substrate; one cake has shrooms with stripes and the others do not; there is no significant difference between one cake and another in water content or anything else. Why does the one cake have striped shrooms? I'm not sure...

i've been told the stripes are indicitive of a harmless bacterial infection, caused by excess water content, but who really knows ?

that sounds somewhere near the mark

One of the shrooms with the stripe has split in half. At first I thought that it was two pins that had combined into one head. some sort of genetic mutation but after stareing at it I realized that it had split. its still growing and the head hasn't darkened any so I'm going to let it continue as it's only about an inch. Anyone ever seen this before?

Humidity too low.

i have been throwing away those shrooms because of stripes. i thought they were contaminated. they were coming out of some cakes that were contaminated. i thought that maybe it was from too much peroxide in my water sprayer

it's a bacterial infection, we think, but it certainly isn't enough of an infection to hurt you; you can eat them

I have a cake that I cut and cased with verm. I noticed that the stems are kinda striped and I remember reading that this was caused by excessive moisture. Do you think that is the case here?

By Tripitydoodah (Tripitydoodah) on Thursday, January 31, 2002 - 09:53 pm:

that is definately the case my friend, not to worry, i personally have consumed those very stripes and they taste great, and they are less filling.

Got a growing issue. A friend has a cake with some brown streaked stems on it and the caps have small white spots.

Questions are:

What is this a symptom of?
How can I fix?
Will they be okay to eat?

Thanks for the help. This is the most comprehensive and friendly source of info around.

they'll be fine. it's caused from excess moisture in the cakes and/or terrarium

By jim brown (Shrhobbyist) on Thursday, February 07, 2002 - 07:51 am:

There isn't really a reason to fix them they are fine to eat.

Is that cake Hawaiin?

By scilly psyman (Madcow) on Friday, February 08, 2002 - 04:52 am:

nope. PFs from Fanaticus. Thanks for the posts Relic and Jim. I'll tell my friend to make sure the kids get more air and less water.
