Extremely Serious. Onset of symptoms from orellanine poisoning can be very greatly delayed (as much as three weeks), the toxin isn't very well understood, and specific treatments are not available. In Finland, rats fed either dried Cortinarius orellanus or dried Cortinarius gentilis suffered severe kidney impairment. The only orellanine poisoning in North America involved kidney failure in a Michigan woman who consumed a Cortinarius species similar to Cortinarius orellanus but found under oaks in 2008. In 2010 this new species was named Cortinarius orellanosus.
Symptoms occur within 36 hours to 3 weeks of ingestion (average is about 8 days), and include nausea, vomiting, lethargy, anorexia, frequent urination, burning thirst, headache, sensations of coldness and shivering (fever generally absent), evidence or progressive kidney failure.
Beyond the standard management of kidney failure, there is little but supportive treatment of use in cases of orellanine poisoning. Patients with severe, but not irreversible damage may begin to recover kidney function between two and four weeks after the onset of symptoms. NOTE: The compounds involved in this syndrome show a very strong uv fluorescence. Both the mushrooms and tissues of the poisoned individual will exhibit this fluorescence.
