"I thought the same in the past. I was so sure they were fungal colonies that I could bet all my money on that."
That sounds like a cognitive awareness of the truth.
"The fact is people have taken those formations to specialized labs ,and they have found nothing but dead tissue."
I have only come across one poster relaying their lab information and the results were merely "luminal contents". And it certainly wasn't a "specialized lab". That doesn't prove much of anything. If you knew what actually goes on in labs, you would know the appalling lack of protocol that often goes on during busy periods. Many have sent in copies of their actual parasites - VISIBLE Tapeworms only to be confirmed as NOT being parasites.
