Out walking in cow country in the mountains above Pocatello, ID the other day, I came across this large fungus. Does anyone know what it is?

    It may be Phaeolus schweinitzii on page 462 of David Aurora’s Mushrooms Demystified first edition; page 570 2nd edition.

    That thing is disgusting looking.

    It may be listed in older books as Polyporous schweinitzii. A common name is dyer’s polypore and another red-brown butt rot because of the type of rot it causes in conifers. Another Arora book “All That the Rain Promises and More . . .” shows a border collie (?) with her chest dyed yellow by mushroom mush; she looks quite pleased with the results!

  4. Yes, Barb, by looking at other photos on the web, it looks like a polyporous. It wasn’t growing under a conifer, though. Some very large Douglas fir were not too far away and their roots probably extended as far as the location of this.

    Ralph, check out the pretty picture of hair pieces dyed by the mushroom under discussion. I couldn’t find a picture of the cute collie. “Tom Volk and Dorothy Beebee modelling the latest in Phaeolus schweinitzii hairpieces!”

    Can you sautee that and put in on a steak?

    Anybody that could eat a steak that big, deserves to die from blocked arteries!

‎"At some point we must draw a line across the ground of our home and our being, drive a spear into the land and say to the bulldozers, earthmovers, government and corporations, “thus far and no further.” If we do not, we shall later feel, instead of pride, the regret of Thoreau, that good but overly-bookish man, who wrote, near the end of his life, “If I repent of anything it is likely to be my good behaviour."
