Cultivating Paxillus involutus

Mainly because I had a seedling birch tree just starting at my home, and I knew that Paxillus was specific specific in my area with birch. And…it worked! Have grown other poisonous species, which may have beneficial effects in bioremediation. For example, some Sclerodermas can concentrate heavy metals (see Mushrooms: Poisons and Panaceas). Others breakdown dioxin, PCP, DDT, etc.

These were small, maybe an inch wide at the largest.

(Why on earth would you want to cultivate P. involutus? It’s poisonous, with that nasty cumulative rhabdomyolysis-causing agent that’s turned up in a few different species of mushroom. Or is it perhaps of interest for pharmacological, rather than culinary, reasons?)

Would need to see gills and stem to be sure. Try doing a search for that mushroom here to see other pictures. Often associated with birch trees in a mycorrhizal association, this was the third mycorrhizal species I cultivated, back in 1985.
