Mushroom Mycelial/Fruit Bodies

Mushrooms DO NOT HAVE circulatory/vascular systems.
If so then how can they suck up oil and stuff like oysters and they can find metals in the fruit bodies.

I think this topic has been adressed before but I can't find it on the forums. Any word?

Bump...As far as scientific fact goes, Stamets has had mushrooms tested in a lab after using for mycoremediaton and found that heavy metals in the soil are taken up into the fruitbodies. That is probably as close to actual proof as we're going to get. RR
As for this being said. That just raises a flag that potency can be increased. I don't know this is interesting

Could you please explain your logic? This information has no relation to psilocybin production. The only correlation I am able to make between your information and psilocybin production is that the heavy metals could act as cofactors to aid enzymatic activity. And even that would be ridiculous seeing as how they would only be needed in trace amounts which could be supplied by a normal diet, any more would just be an unnecessary excess.

You are correct. Mycelium doesn't have a vascular system. It's composed of long cells, stacked end to end to form a network. It doesn't take a circulatory system for heavy metals to be absorbed. Other substances are metabolized by the mycelium. That's why mushrooms can grow on manure, but we don't get e coli from eating mushrooms. However, according to stamets, if there's lead or mercury in the soil, they will absorb it. I've never personally tested for such. RR

Those be some nasty thoughts RR... I would like to think most of our substrates don't come packed with mercury...

Nutrient transport in the trough system of mushroom culture Nielsen and Rasmussen (1962) designed deep trays to investigate the transport of nutrients in mushroom mycelium to the developing fruit-bodies. Radioactive phosphorus (P32) was applied at the base of spawn-run trays ranging from 30 to 180 cm deep, and the harvested fruit-bodies were tested for radioactivity. As the total uptake of P32 by the mushrooms in the deeper trays was considerably lower than from the shallow trays, it was concluded that compost close to the casing soil layer was more efficiently exploited by the mushroom mycelium than compost further away.
