Underwoodia
Underwoodia is a genus of ascomycete fungi in the family Helvellaceae, described by Charles Horton Peck in 1890 to honor mycologist Lucien Marcus Underwood. The genus contains three species with widespread distribution. Northern Hemisphere species (U. columnaris) occur in North America, while Southern Hemisphere species previously classified in Underwoodia have been reclassified to the resurrected genus Geomorium (family Geomoriaceae). Underwoodia species are ectomycorrhizal fungi associated with forest ecosystems.
