HAMILTON, Ontario, Dec. 6 (UPI) -- A Canadian biologist say his trek in southwestern China has shattered a myth of "killer mushrooms" being responsible for 400 unexplained deaths in the region.
Jianping Xu of McMaster University in Ontario said his investigations were triggered by a 2010 article in the journal Science, claiming Trogia venenata mushrooms contained high concentrations of the metal barium and linking them with high blood pressure, cardiac arrests and sudden deaths in southwestern China over the past 30 years.
