A negative association with Trich in terms of mushroom culture is to be expected, I'd imagine. Evidently Trich is a predatory fungus that destroys other fungi. Obviously beneficial for plants that are sensitive to fungal attack and a problem when raising mushrooms.
Products like Great White mentioned above also contain mycorrhizal fungi and beneficial bacteria to aid root development. I thought Sarrraciniacae -- and all carnivorous plants for that matter -- were non-mycorrhizal though.
