**********

Opuscula Philolichenum is intended to serve as a venue for the publication of small works in the field of lichenology (including lichenicolous fungi and non-lichenized fungi traditionally treated with ). The journal is primarily electronic, available on-line free of charge (at http://sweetgum.nybg.org/philolichenum/), with a limited print run to satisfy the requirements for effective publication established under the International Code for Botanical Nomenclature. The central goal of the journal is to provide timely publication, in a professional format, free of charge to authors and readers. While the journal focuses on topics relating to the biota of North America this is by no means exclusive and manuscripts on other topics will be considered as the table of contents of the present issue clearly illustrates. Authors wishing to submit a manuscript for publication in Opuscula Philolichenum should contact the editor prior to submission to confirm that the paper conforms to the mission of the journal (outlined above). Manuscript submissions should be left unformatted and authors should consult a recent issue of Opuscula Philolichenum for style. All submissions are subjected to review by at least two peer reviewers and, following acceptance are formatted by the editor. As has been noted in the preface to previous issues the backbone of any scientific journal is its cohort of reviewers. As such the editor would like to take this opportunity to thank those who graciously provided peer review of manuscripts published in this volume: Robert Egan, Jack Elix, Theodore Esslinger, Howard Fox, Alan Fryday, Curtis Hansen, Richard Harris, James Hinds, Klaus Kalb, Martin Kukwa, Robert Lücking, Bruce McCune, Jolanta Miadlikowska, Caleb Morse, Walter Obermeyer, Frederick Seavey, Harrie Sipman, Laurens Sparrius, Goran Thor, Mats Wedin, Martin Westberg, and Timothy Wheeler. The editor also extends his sincerest thanks to the associate editors whose efforts in editing and proofing manuscripts, soliciting manuscripts, and corresponding with authors have greatly improved the quality of the journal. Thanks also to Brendan Hodkinson and Melissa Tulig for their help with the online presence of this journal.
