Cap Contam, or Just Myc?
    #7179577 - 07/15/07 03:05 PM (17 years, 6 months ago)

Hi Everyone,

Hopefully just a quick one. Do the attached pics show contamination, or mycelium on the cap of the distorted shroom? There is only one "contaminated" shroom. It seems to have stopped growing over the past few days. This is flush 6 of B+ on cased WBS. I've been spraying quite heavily, and fanning, doing both twice a day. The ambient temp. is about 22 - 25 deg.c.

My view is that it's too ropey to be cobweb, but I maybe wrong, or it may be something else.

I'm a noob - this is only my second grow, and my first attempt at casing.

Any comments would be welcome. :smile:

That looks fucking gross. I'd pluck it and toss it out.

nasty.

It appears to be bacterial blotch or possibly verticillium or something similar. Pick that one and get rid of it.

Thanks for the replies. I hear your wise words and have removed the offending shroom. I cautiously smelt it, and all I could smell was the usual mushroomy scent. But the cap is fairly soft, though not rotten as such. This is a picture immediately after I cut the shroom in half:

I other words, that nasty looking dark blue/black was there before I cut it, not due to oxidation. No wonder it stopped growing, it was very sick.

When I squeezed the fuzzy area at the bottom of the shroom, water drips appeared. You can see how wet it is in the bottom of the picture. I think I'm over-spraying, and that may have encouraged this contam.

Thanks once again.

Thanks. It's a Sony DSC-P93. Five Megapixel, 3x zoom, auto and various other shooting modes. Nothing special, but it does have a macro mode, which I used to take the pictures. It's a few years old though - not sure if you can buy them new any more.

I then reduced the picture file size (2MB to 100KB) so I could upload it (I'm still on dial up :frown:)

After closer inspection, some reading and thought, I'm pretty sure that this is Verticillium (Dry Bubble). What's interesting, is Stamets says in The Mushroom Cultivator about Verticillium:

"History, use and/or medical implications: Apparently inocuous, no pathogenic species are known." (Chapter 8, page 317)

which tends to suggest that mushrooms infected with Verticillium can be eaten safely. Interesting :smirk:
