Free ISA CEUs: Week of January 5th, 2026
The new year brings new opportunities to learn about trees. Consider attending a webinar discussing oyster mushrooms in North American forests.
Wednesday, December 17th
Beyond cultivation: tracking the spread and ecological effects of the golden oyster mushroom @ 11:00am MST
Arboricultural Association Wednesday Webinar Series presents Beyond cultivation: tracking the spread and ecological effects of the golden oyster mushroom with Michelle Jusino. The golden oyster mushroom (Pleurotus citrinopileatus) is a popular edible fungus that has recently emerged as an invasive species in North American forests. Building on recent work published in Current Biology, this talk will summarize evidence that golden oyster mushrooms are spreading rapidly and are associated with reduced native fungal diversity on colonized trees. I will also highlight ongoing efforts to develop molecular tools for detection and monitoring of this species, and discuss future research directions needed to assess ecological impacts and inform management.
