Recent field work in the Petersburg Borough of southeastern (SE) Alaska has led to the discovery of two species of lichenized fungi in the Ostropales that are here described as new to science: Jamesiella dacryoidea Fryday, which has green-grey dacryoid thlasidia, and Sagiolechia bairdensis Fryday, which has very small apothecia (<0.2 mm diam.), 3-septate ascospores and a trebouxioid photobiont. A key to the North American species of Sagiolechia and Gyalidea is also provided. In addition, Bryobilimbia ahlesii (Hepp) Fryday, Printzen & S.Ekman is reported for the first time from Alaska, along with records of several other species that have rarely been collected in the state.
