No, there's no evidence against Tegmark's math.

Finding isolated quantum effects is emphatically unsurprising: after all, everything is quantum. It's just limited in locality, which is basically what Tegmark is talking about (locality and decoherence time being somewhat dual).

There is no evidence for the kind of quantum effects that would involve multiple neurons. This is quite a block, since afaik, even the quantum-woo types (Penrose, emphatically) are not claiming that consciousness comes from the quantum behavior of a single neuron. (And that would be profoundly ignorant of basic neuroscience.)
