In this region, aspen is plagued. Sapling-sized quaking aspen (Populits tremuloides) in five natural clones were inoculated with mass and single ascospore cultures of Hypoxylon isolates varied in ability to produce cankers.
'Conidial-type' isolates generally produced few cankers, while 'mycelial-type' isolates produced cankers on % of inoculated branches. According to Discover Magazine, the quaking aspen tree is the largest organism on the planet.
