What are these please

I have a customer and he has this in his crawl space, it’s been growing for at least 3 years.

it's very hard to identify fungus by looking at it. you have to do a spore print, and know how to read it, to be sure what it is.

pretty good video, even though the guy talks too much. once you have the spoor print, you can compare it to pictures, see if it's even close to what you want
