Do I have Cobweb? Is it dangerous? Can my harvest be OK

I am currently fruiting Reishis in my fruiting chamber. Unfortunately I am noticing something growing on the fruiting bodies, which I fear is cobweb. I would like some advice of what to do.
These are Reishis so they have a very strong fruiting body. If it is cobweb, can I clean the Reishis off and use them for extract even though some cobweb has been growing on them?
I also have some Lion's Mane growing in the same fruiting chamber, fruiting like mad, can I count on them being affected as well? I do not see any cobweb growing on them, but can it bee there even though I do not see any?
Here are some pictures:



This coming picture is what convinced me that there is something growing on the surface. See the area before I scratch it with my finger:

And here is after I scratched:


All the fruiting bodies of the Reishis seem to have these darker patches ...

Like I said I hope that something can be salvaged.
How do I best clean the fruiting chamber after an attack like this?
Kind regards Johnny

I would call this highly contaminated(likely due to improper growing environment) Ganoderma luccidum

Thank you Tmethyl.
Yes, it is highly contaminated.
What I am interested in is to learn something from the experience, I would like to know what contaminant it is (cobweb?), what that contaminant thrives in (too low FAE?) etc. that is I am seeking to highlight conditions and parameters that I can alter so that I can avoid this in the future.
If anyone in this forum is able to address my questions more in detail so that I could help build my own and other people's knowledge I would be very grateful.
(Of course if I am in the wrong forum I would be grateful for a hint at which forum is the correct one.)
Kindest regards Johnny

I have started to feel the slight irritation in my nose (running), along with the cough, so I need to just get rid of the whole Reishi lot.
I would very much appreciate if someone could comment on how to avoid cobweb (which I believe it is) in the future. A 13-year-old post suggested that FAE and light would help. Does someone agree/disagree?
Kind regards Johnny

Mold thrives in high co2 and low FAE environments. Air movement is your friend.

Thank you for your response. Yes, I will probably do something serious to enhance the FAE in the fruiting chamber.

FAE will surely help, and a mix of water and hydrogen peroxide will help slowing down the mold if the harvest is close.
Also clearing your grow area, then spraying air and every surface (floor, walls, the ceiling) with 5-10% bleach solution once or twice may help getting your grow are clear of spores. Also you should clean your equipments before you bring them back.

Thanks again Tira :-)
What would be the concentration of the hydrogen peroxide used for slowing down mould? Could this be used to spray as a matter of prevention, I mean keeping the casing layer a bit peroxidated at all times?
Kind regards Johnny

I don't remember the exact ratio, you can look it up from the search engine.
Some do that, but it also seems to slow down mycelial growth a bit. In my opinion, having clean spawn, properly pasteurized substrate/caasing, keeping growth conditions optimal and grow area clean seems to be enough.
As I said before, I were to have mold issues regularly, I would empty and clean my grow area and also clean the equipments.
I've recently read that Paul Stamets sprayed down his grow areas with bleach solution between grows, kept it closed for 24 hours (so bleach vapor does its job), and ventilated till the vapor is gone and wiped down the place after that. I use similar but less drastic methods, seems to be effective.

OK, got it.
Hmmm, I grow mushrooms at home, so I can't really fill my home with bleach, but I'll figure out something. (Perhaps I'll buy an air filter and run on low at all times.) Anyways I'll think of something.
Thank you again for your support. And I also send best wishes for your part of the world. You're having a tough time now! (In Sweden we see a mere fragment of the suffering you are seeing. But we feel it too.)
Kind regards Johnny

You can bleach bomb the room, still doesn't fix the underlying issue of needing to be clean when needed. In all my years I have literally never bleached a room, and I've seen A LOT of contaminations. Instead of doing that, I worked on my procedures. I thought it was strange only some substrates would cobtaminate, but not others. If the room was to blame all of them would cobtaminate. But it was actually because the substrates that did contaminate were weakened with bacteria.
I've at most vacuumed the carpet. These bags, did you just straight inoculate into them or spawn to them? If the latter you need cleaner spawn. If the former, you need to work on your inoculant. Increased FAE will help, but IME if you got a healthy clean substrate, even low FAE won't contaminate.

Thank you for your reply.
Mmm, I am pretty good with sterile procedure ... I believe that the issue is that I am actually having the fruiting chamber in my kitchen which probably not is a good idea. I am thinking of how to get around that.
Still the Lion's Mane seem to be resistant towards cobweb or it is that I cannot see them growing on the fruiting bodies.
Kindest regards Johnny
