Nice Stephen I'll have to try that out. Seems like a fungal-dominant 'bomb' for sure. I don't think the delicate mycorrhizal fungal hyphae would survive, but the mycorrhizal spores have a hard exterior shell and would probably remain intact. I bet the white fuzzy part in your mixture is full of nutrient-cycling saprophytic fungi that are the primary decomposers of dead organic matter in soils, sounds good to me :)
