Mycelium eating a contam?

During my first ever go at the hobby i did the PF tek like almost all noobs... But one jar at the time got a small spec of trich about the size of a pea. I was using a cambodian strain from a ms syringe; anyways getting to the point... I witnessed the cubensis mycelium take over the trich over the course of 3 days and later fruited said jar with all the others. The trich came back on said cake on the 3rd flush.
Anyone else witnessed this? or have a similar experience? A contam eating strain sounds pretty favorable lol

Your mycelium most likely ate a trichoderma lookalike. Like aspergillus or penicillium. And as you noticed the myc just contains it until it's too weak to contain it.
Trichoderma isnt the case because it's genetically impossible for mycelium to overrun trichoderma.

Thank you for clearing that up for me. But that leads me to wonder, was the mycelium that contained the contaminate a strong strain in a sense that it was able to do that? Or is it likely just random genetics causing it to be able to "contain" it?

I've seen aspergillus get contained tons of times in fact almost every time it appeared on a petri dish it gets overrun. But if you look underneath you can still see this huge dark circle of aspergillus waiting for the mycelium to die.
Idk it doesn't seem like it's all that difficult for myc to contain it IME. I'd be more worried about keeping a culture clean

I doubled checked some of your info, while its most likely right, you should be sure that the chart you posted doesnt change with the type of fungi, the bottom fungi in the chart (one in question) is plant-pathogenic witch means its a fungi that only infect plants which i dont think cubensis does.

No cubensis is Saprotrophic. So it shouldn't be classified as a plant pathogen, however it still applies to trichoderma and higher fungi, which cubensis is.

I posted this a few weeks ago and pissed a few people off I think.
I'm fruiting PF cakes now over 5 months old that were contaminated with something, came back to look at them months later, and they looked nice and white, seem fine. Taking forever to pin. Been in FC for a month now I think and pins are finally coming in
