Is this Bacterial Blotch? (First grow).
    #12420366 - 04/19/10 12:38 PM (14 years, 2 months ago)

A part of one of my caps looks like this Bacterial Blotch pic:

Here's some pics of my cap:






It looks a lot like that example pic, to me. What can I do to save it? Do I have to pick it and get rid of it? Do I have to get rid of the cake?


Please help,
Rocket

It does look like bacterial blotch. Once they are 100% cracker dry they will be safe to eat.

I didn't read this (which is where I fund the example pic):

Bacterial Blotch – Pseudomonas tolaasii (P. fluorescens)

Yellow to brown lesions form on mushrooms. Typically, spotting occurs at or near the edge of mushroom caps. Blotch occurs when mushrooms remain wet for a period of 4 to 6 hours or longer after water has been applied. The bacterium is spread in air-borne soil particles. Controls include lowering humidity and watering with a 150 ppm chlorine solution (calcium hypochlorite products are used since sodium hypochlorite products may burn caps). If the mushroom stays wet, however, chlorine has little effect since the bacterial population reproduces at a rate that neutralizes the effect of the oxidizing agent. Shiitake caps are affected by a bacterial disease caused by Pseudomonas gladioli (Burkholderia gladioli). Sanitation is a critical component of control measures.

I don't have a 150 ppm chlorine solution ar the moment. Is that info still accurate? Like to find out more. Been searching on here. I haven't fund any info that I'm confident with yet.

When should I dry it? Can I let it grow bigger, or do you know if I shouldn't because it could spread to the other shrooms? Because it's "air-borne". I think I just read some where to pick it off and dry it right away.
