Hypogeous-fungi
Guides
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.
Leiodes
round fungus beetles
Leiodes is a genus of small, rounded beetles in the family Leiodidae, comprising at least 110 described species with a primarily Holarctic distribution. Most species are subterranean mycophages, with several species acting as economically significant pests of truffle orchards. The genus exhibits specialized morphological and behavioral adaptations for life in ephemeral and solid fungi, including unique larval structures such as pseudomycangia.
