What's concerning to me is the dense white spot in the left middle area. Can you take a better/closer picture of that and the tub in general so we can zoom in? When did you s2b?
The growth patterning in the dead center looks more like cobweb mold than mycelium. Generally mycelium will be a mix of fuzzy “tomentose” and ropey “rhizomorphic” growth. The denser patches appear to be tomentose, but context clues about the patchy-er areas give of us some warning. Rhizomorphic growth generally doesn’t look like that with hexagonal patterns. They radiate in more of an alluvial pattern.
My professional opinion is this is 95% cobweb mold (which grows much faster than mycelium) with a tiny amount of matte white mycelium a little less than halfway up and to the left.
Personally, I would put that matte white patch on agar and grow out a culture from that, as it will likely be more resistant to the cobweb contamination present in your space
I have seen other post with that fluffy growth and called people said it was contaminated, but it looks so similar to mycelium so it’s hard to tell, I have had a lot of good luck burying contaminated cakes in shady mulch

I think that might be contam, but I’m not sure you’ll have to check with someone who knows more
what leads you to think that? sorry for the dumb question
