Nectria on roots of Neofinetia Falcata

[Longroots]

I recieved this orchid 4 months ago, and so far it has put out a tiny bit of a new leaf. I did put it into semi hydroponics, and earlier, it popped a dead brown root out of the pot and I saw some red balls on it that look identical to Nectria. The other Neofinetia has taken very well to semi hydro, put out a new leaf and seems happy, although the this Neofinetia also seemed ok.

I've repotted it into a bark/moss mix (having removed this bit of dead root) in a Dracula basket, ran hydrogen peroxide through the roots, then ran over it with rain water. It is now quarantined. I've seen previous threads say this is a strain of fusarium, and that throws up mixed feelings for people here I know. Is there a chance that this is a Nectria fungus that isn't fusarium? It was only on the dead root tip, no where else. Is it likely to be fusarium after having it for 4 months? Is the other Neofinetia doing well in semi hydroponics because it doesn't have fusarium to set it back?

I'm keeping it for now, but if it gets worse, I'll throw it, and definitely not use the vendor again, as I've had issues with a plant arriving with cymmv.

Thanks
