Physoderma is a genus of chytrid fungi. Described by German botanist Karl Friedrich Wilhelm Wallroth in 1833, the genus contains some species that are parasitic on vascular plants, including P. alfalfae and P. maydis, causative agents of crown wart of alfalfa and brown spot of corn, respectively.[3] Of the chytrid genera, Physoderma is the oldest.[4] However, species were confused with the rust fungi, the genus Synchytrium, and the genus Protomyces of Ascomycota.[5] Members of Physoderma are obligate parasites of pteridophytes and angiosperms.[4] There are approximately 80 species within this genus (depending on whether one includes those traditionally belonging to Urophlyctis).[5]
