Dermocybe orellana (Fr.) The therapy is directed toward the renal failure, including dialysis and possible transplantation. 18 (1):121. Orellanine seems to cause almost no reaction in glomeruli, although in an animal model, elimination of orellanine was almost exclusively by glomerular filtration. The toxin orellanin is solely nephrotoxic and renal affection can lead to acute renal failure. It is occasionally found in southern Britain. Within the genus it belongs to a group known as the Orellani, all of which are highly toxic—eating them results in kidney failure, which is often irreversible. 2018 Aug 17. 2004 Sep. 22(5):335-404. 2nd ed.

Of the thousands of mushroom species that are increasingly studied and collected by amateur mushroom hunters, about 100 can cause serious illness, but only about 10 cause death. Although mushroom poisoning is a rare cause of acute renal injury, in some cases it may lead to the development of a severe and irreversible renal failure.
