Abstract
Two collecting trips in Gaspesian Park, Quebec, during the summer of 1957, yielded a considerable number of pyrenomycetes. In this paper records of 87 species or varieties in 46 genera are presented. Two new species, Linocarpon umbelliferarum Barr and Pseudomassaria foliicola Barr, are described. Five previously described species are transferred to other genera, and the following new combinations are proposed: Gibbera cassandrae (Peck) Barr, Gibbera grumiformis (Karsten) Barr, Gibbera kalmiae (Peck) Barr, Gibberidea kalmiae (Peck) Barr, and Limacinia arctica (Woronichin) Barr.
