I always get cobweb--Where does cobweb come from??

My last several casings have all picked up cobweb, and I can't figure out why. Where does cobweb mold usually live, and how can I eradicate it from my household? I am getting sick of it. I am trying to save a couple casings right now with h2o2 and salt.

Cobweb mold is the easiest to get and the easiest to get rid of. It's about the only contaminant I recommend trying to save a project from. Cobweb is in the air, everywhere. It requires stale, still air to grow. You'll need to up the air exchange to prevent it from forming. Once formed, simply put 3% peroxide full strength from the bottle into your mister and douse the casing layer. The cobweb will melt on sight. A second application might be required the next day. Be sure to pasteurize, never sterilize casing material. A sterilized casing layer will contaminate very easily. RR

The scientific name is Dactylium Mildew Here you can learn all you ever wanted to know about Dactylium Mildew. http://mushgrowinfo.cas.psu.edu/cobweb_mildew_fact_sheet.htm

I would attempt to revert back to the pf tek and see if you get cobweb mold on your cakes. If you can make successful cakes, then you will surmise that you are getting cobweb mold sometime between casing and incubation. It appears that it all comes down to hygiene.

Ok,
Here we go again. I had a casing that was doing PERFECTLY. I birthed it, and there wasn't a hint of contamination anywhere. I checked it last night, and it was fine. Then I woke up today and there was cobweb ALL over the entire casing. I just sprayed h2o2 all over it, but it's pointless by now. I'll be throwing it away.
It must be something I'm getting IN the birthing tub. I cleaned that tub extremely well with detergent and lysol. I need to know how to keep this from happening. I'm losing casing after casing, and I'm convinced I'm getting the contamination after it goes in the birthing tub.
Help!

First, we don't normally birth a casing. We apply it as a layer over the top of our substrate.
Second, there is no need to throw away anything with cobweb mold. It is about the only contaminant that is actually easy to recover from. Simply spray 3% peroxide right from the bottle and watch the cobweb disappear.
As I said in the post above, cobweb mold can not live in an environment with fresh, moving air. It only grows in stale, still air. Cobweb is prevented by proper air exchange. Cobweb spores also die at 120F, so a simple pasteurization is sure to kill them off. Giod luck. RR

I also got cobweb in oak substrate with lions mane dowels. Peroxide wont kill mycelium? How to provide proper air flow in closed jars?

If you have a cobweb like contamination in a jar it's probably rhizopus or mucor not dactylium. It's common to get these confused.
Quote from Kizzle on cobweb: " This has been long overdue, I'll start by explaining what led me to post this. I've been growing mushrooms for a good 4+ years but not until fairly recently, after assisting with the culitivation of Agaricus bisporus, did I start to suspect that what I had always considered cobweb mold may actually be something else. Unlike the competitor molds you're used dealing with cobweb mold is a mushroom pathogen. It's occurrence is in no way linked to contaminated spawn and is rarely a problem in bulk substrates. To ignore that and misidentify other molds as cobweb is counterproductive to determining the source of contamination problems and what to do about them. In trying to make sense of contradicting information I've read a huge amount of information from books, published studies, experiments, etc and thought I'd share some of it.
just to clarify things up front, the term cobweb mold is often used loosely to refer to any kind of thin whispy grey mold and that's not what I'm referring to. Hopefully I can help distinguish the difference between these molds and the specific mold that causes cobweb disease. " (end quote)

Can you ID this for me? It's hard to tell if its mycelium or something else.
