Genea
Genea is a genus of hypogeous fungi (truffles) in the family Pyronemataceae, containing approximately 32 species. The genus produces small, soil-colored underground sporocarps that are challenging to locate visually. A 2024 study using scent-detection dogs in western Oregon demonstrated the value of trained dogs in documenting this difficult-to-find genus, revealing abundant occurrence across a wide elevational range and sensitivity to wildfire disturbance.
