Welcome to PSMS!

We are an organization that encourages the research, education, cultivation, hunting, identification and the cooking of mushrooms. With over 1,200 members, PSMS
is one of the largest mycological societies in the country.

We share our knowledge about mushrooms through meetings, classes, workshops and field trips.

Please join us at a meeting or become a member today!

Korena Mafune - Old-growth temperate rainforest in Western Washington: Exploring fungal mutualism in canopy soils

Doors open at 6:30 pm at the Center for Urban Horticulture. Come early and bring any mushrooms you want identified!

The temperate rainforests of Western Washington are known for their temporally stable old-growth forests. In Olympic National Park, many old-growth trees have developed thick layers of organic canopy soils on tree branches. Acer macrophyllum (big leaf maple) has adapted to canopy soils by growing extensive adventitious roots that are forming unique fungal relationships. Her research focuses on determining if the community diversity of mutualistic fungi in canopy soils enhance the resilience of Acer macrophyllum to seasonal extremes. Her presentation will briefly introduce the complexity of the parallel evolution between plants and fungi, and will turn to focus on preliminary evidence that suggests that adventitious canopy roots may be associating with different fungal species than forest floor roots.

Korena Mafune is a Washington native, and has always had a passion for being outdoors. It was during her undergrad that her interest in plant-fungal associations really started to grow, and she started working with canopy soils in the temperate rainforests. She continued into the Master's program in the School of Environmental and Forest Sciences at UW, receiving her Master's in 2015 and continuing with PhD research. Korena received the Ben Woo Scholarship from PSMS in 2016. This helpful contribution allowed her to collect preliminary data on fungi in canopy soils, which resulted in pulling in more funding for her current, much larger research project. Even after the PhD, she hopes to continue elucidating the role of fungal interactions in the Pacific Northwest's rainforests. On her free time, she enjoys foraging, cooking, spending time with family and pets, and training martial arts.
