Pluteus is a cosmopolitan euagaric genus found commonly on xyloid (woody) substrates. A taxonomic revision is presented for species of Pluteus section Celluloderma known from the U.S.A. Type studies of all taxa originally described from the U.S.A. as well as additional morphological data and keys are presented. Two new species, Pluteus deceptivus and Pluteus phaeocyanopus, and one new variety, Pluteus seticeps var. cystidiosus, are described, and the new name, Pluteus homolae, is given for Prunulus ludovicianus. Notes are provided for two extralimital taxa and three taxa that are doubtful or excluded from Pluteus section Celluloderma.

Key words: Ascomycota, erose soralia, lichens, Parmelia barrenoae, Parmelia sulcata, Parmeliaceae, rDNA internal transcribed spacer.
The foliose lichen Parmelia barrenoae is newly reported for North America based on material collected throughout the western United States ( California, Idaho, Oregon, and Washington) and for Africa based on material from the Middle Atlas mountain range of Morocco. In addition to morphology, ITS sequence data were examined to confirm the identity of North American material. The species was originally described from the Iberian Peninsula of Europe, and has not been reported from anywhere outside of that region since its description. A revised account of the species is provided in light of the additional material now available from geographically diverse populations.
