Abstract: Urnula padeniana is described as new although it is a common northwestern American species known for years as Sarcosoma mexicanum or Plectania mexicana. A morphological in-depth study of this species is reported. The type of Bulgaria mexicana is also revised, and turns out to be a different species, being a member of the Urnula campylospora complex. The new combination Urnula mexicana is proposed. Color pictures of fresh and dried specimens, microscopic morphology, and a black and white plate of hymenial elements are included. Related or similar species are also discussed
