Forskningsöversikt (refereegranskat)abstract
- Recent molecular phylogenetic analyses and morphological Studies have shown that it is necessary to revise the present morphology-based generic delineation of the lichen family Verrucariaceae in order to account for evolutionary relatedness between species. Consequently, several genera were recently described or resurrected, and others were re-circumscribed. As an additional step toward this generic revision, three new genera (Hydropunctaria, Parabagliettoa, Wahlenbergiella) and eleven new combinations are proposed here. A summary of the Current taxonomic and morphological circumscription of all genera investigated so far is also presented. Several monophyletic groups are identified for which further taxonomical changes will be required, but for which taxon and gene sampling is presently viewed as insufficient. Clear morphological synapomorphies were found to be rare for newly delimited genera. In some cases (reduced morphology or plesiomorphism), even the combinations of slightly homoplasious phenotypic characters do not allow a clear morphological generic circumscription. Molecular features are envisioned as characters for delimiting these taxa.

- We compiled literature, intensively studied 15 sites as a group, and collected opportunistically in other areas of the Yosemite National Park. We report a total of 562 species of lichenized fungi from the Park, adding 461 species to the total of 101 species reported for the Park by the National Park Service database. An additional 22 lichenicolous fungi are reported here. Two nonlichenized fungi associated with young living twigs of particular host species are also included. An additional 75 species that are known from nearby areas in the Sierra Nevada, but not yet from Yosemite, are listed. Fourteen species are apparently newly reported for the Sierra Nevada, with an additional 17 species new to California, and five species new to North America (Gyalidea fritzei, Pyrenopsis reducta, Lecanora pseudosarcopidoides, L. sarcopidoides, L. subravida). Two taxonomic changes are included here: Verrucaria carbonusta Breuss is newly described, and Lecidea fuscoatrina Hertel & Leuckert is synonymized under the earlier but neglected name, L. cascadensis H. Magn.

- We inventoried lichens in Kenai Fjords National Park in Alaska, USA We assembledthe known information on occurrence and ecology of lichens in this park by combiningfield, herbarium, and literature studies. Our results provide baseline data on lichenoccurrence that may be used in resource condition assessments, vulnerability assessments, long-term ecological monitoring, and resource management. We report a total of 616 taxa of lichenized fungi from the Park, plus an additional five subspecies and three varieties, all of which are new additions to the National Park Service database for this park unit. An additional five species of nonlichenized lichenicolous fungi are reported here. Eight non-lichenized fungi that are traditionally treated with lichens are also included, most of these associated with bark of particular host species. Four taxa new to North America are reported here (Arctomia delicatula var. acutior, Aspicilia dudinensis, Myriospora myochroa, and Ochrolechia bahusiensis), along with 44 species new to Alaska. Numerous species have been confirmed using ITS barcoding sequences. Also several records assigned to the genus level are reported, many of those are likely new species.
