Now what? Tiny mushrooms?

[greenpassion]

Being an orchid mom is never ending! Last week, I had posted about one of my phalaenopsis that had a floppy New Leaf. ES responded with info, and I took the suggestion it may need water. I watered it and the new Leaf stood back up as usual. But I have struggled with this new Leaf flopping over since that last post. I pulled it out of the ceramic decorative pot that the actual pot is in. It is clear plastic and I can clearly see the roots. but not only can I see the roots, I see very small thin stemmed mushrooms throughout the mix. Even though she is in Spike and flowered fully bloomed on her old Spike, I'm thinking I need to get her out of that mix and into fresh bark. To tell the truth I can't remember if she is planted and what I bought her in or if I had repotted it. I get a feeling that this is what she came in because none of my other orchids have ever had this. Could this I'm guessing fungal stuff Be the cause of the continually flopping New Leaf? She is otherwise completely healthy. Stiff perky leaves, 8 beautiful flowers on her. It's quite bizarre.
