Opuscula Philolichenum, 15: 56-81. 2016. *pdf effectively published online 25July2016 via (http://sweetgum.nybg.org/philolichenum/) Lichens, lichenicolous fungi, and allied fungi of Pipestone National Monument, Minnesota, U.S.A., revisited M.K. ADVAITA, CALEB A. MORSE1,2 AND DOUGLAS LADD3 ABSTRACT. – A total of 154 lichens, four lichenicolous fungi, and one allied fungus were collected by the authors from 2004 to 2015 from Pipestone National Monument (PNM), in Pipestone County, on the Prairie Coteau of southwestern Minnesota. Twelve additional species collected by previous researchers, but not found by the authors, bring the total number of taxa known for PNM to 171. This represents a substantial increase over previous reports for PNM, likely due to increased intensity of field work, and also to the marked expansion of corticolous and anthropogenic substrates since the site was first surveyed in 1899. Reexamination of 116 vouchers deposited in MIN and the PNM herbarium led to the exclusion of 48 species previously reported from the site. Crustose lichens are the most common growth form, comprising 65% of the lichen diversity. Sioux Quartzite provided substrate for 43% of the lichen taxa collected. Saxicolous lichen communities were characterized by sampling four transects on cliff faces and low outcrops. An annotated checklist of the lichens of the site is provided, as well as a list of excluded taxa. We report 24 species (including 22 lichens and two lichenicolous fungi) new for Minnesota: Acarospora boulderensis, A. contigua, A. erythrophora, A. strigata, Agonimia opuntiella, Arthonia clemens, A. muscigena, Aspicilia americana, Bacidina delicata, Buellia tyrolensis, Caloplaca flavocitrina, C. lobulata, C. -

Lichens and Allied Fungi of the Indiana Forest Alliance
2017. Proceedings of the Indiana Academy of Science 126(2):129–152 LICHENS AND ALLIED FUNGI OF THE INDIANA FOREST ALLIANCE ECOBLITZ AREA, BROWN AND MONROE COUNTIES, INDIANA INCORPORATED INTO A REVISED CHECKLIST FOR THE STATE OF INDIANA James C. Lendemer: Institute of Systematic Botany, The New York Botanical Garden, Bronx, NY 10458-5126 USA ABSTRACT. Based upon voucher collections, 108 lichen species are reported from the Indiana Forest Alliance Ecoblitz area, a 900 acre unit in Morgan-Monroe and Yellowwood State Forests, Brown and Monroe Counties, Indiana. The lichen biota of the study area was characterized as: i) dominated by species with green coccoid photobionts (80% of taxa); ii) comprised of 49% species that reproduce primarily with lichenized diaspores vs. 44% that reproduce primarily through sexual ascospores; iii) comprised of 65% crustose taxa, 29% foliose taxa, and 6% fruticose taxa; iv) one wherein many species are rare (e.g., 55% of species were collected fewer than three times) and fruticose lichens other than Cladonia were entirely absent; and v) one wherein cyanolichens were poorly represented, comprising only three species. Taxonomic diversity ranged from 21 to 56 species per site, with the lowest diversity sites concentrated in riparian corridors and the highest diversity sites on ridges. Low Gap Nature Preserve, located within the study area, was found to have comparable species richness to areas outside the nature preserve, although many species rare in the study area were found only outside preserve boundaries. Sets of rare species are delimited and discussed, as are observations as to the overall low abundance of lichens on corticolous substrates and the presence of many unhealthy foliose lichens on mature tree boles. -

MycoKeys 70: 39–58. https://doi.org/10.3897/mycokeys.70.51569 Abstract Lecanora baekdudaeganensis Lee & Hur is described as a new lichenized fungus from Baekdudaegan Mountains, South Korea. The new species is classified into the Lecanora subfusca group – allophana type and distinguishable from Lecanora imshaugii Brodo by a darker thallus, brownish disc, K–insoluble gran- ules on the surface of the epihymenium, shorter hypothecium, and the presence of oil droplets in the apothecial section. Molecular analyses employing internal transcribed spacer (ITS) and mitochondrial small subunit (mtSSU) sequences strongly support Lecanora baekdudaeganensis as a distinct species in the genus Lecanora. A surrogate key is provided to assist in the identification of all 52 taxa in the genus Lecanora of Korea.

Tools for Identifying Biodiversity: Progress and Problems – pp. 295-299. ISBN 978-88-8303-295-0. EUT, 2010. Identifying algal symbionts in lichen symbioses Martin Grube, Lucia Muggia Abstract — Lichens are a ubiquitous terrestrial symbiosis of fungi with photoautotrophic microorganisms. The identification of the hosted photoautotrophs is notoriously difficult. Molecular data to clarify evolutionary relationships on the involved algal and cyanobacterial lineages are accumulating, but the assignment to species is challenging for various reasons. One of the challenges is the limited knowledge on the alpha diversity of photoautotrophs. New lineages are being discovered with increasing amounts of sequencing. Identification tools could incorporate these aspects, by routinely updating the assignment process. We propose the establishment of a classification tool using algal sequence data from public databases. Index Terms — lichens, symbionts, photobionts, ITS, actin. —————————— u —————————— 1 introduction ichens are symbioses of fungi and photoautotrophic partners (algae and/ or cyanobacteria). Lichens are widespread in all climatic zones and cover more than 8% of the land surface [1]. Lichens are generally named after Lthe morphology-determining fungal partner which represents more than 18.800 known species of Ascomycetes [2]. Contrarily, the knowledge about photobiont species diversity is still limited. The determination of lichen photobionts is complicated due to the lack of diagnostic characters for routine analyses. Algae in lichenized stage do not express useful characters at all, and cultivation of algae is time-consuming and not yet possible for some lineages [3]. -

En- dococcus freyi Hafellner, detected on Umbilicaria cylindrica (type locality in Austria), is described as new to science. The new combinations Endococcus umbilicariae (Linds.)

Over the time, 277 species and infraspecific taxa have been assigned to Microthelia, now a rejected generic name against the conserved genus Anisomeridium (Müll.Arg.) M.Choisy. In the second half of the 19th century also several lichenicolous fungi have either been described in Microthelia, namely by the British mycologist William Lauder Lindsay (1829–1880), or have been transferred to Microthelia by combination.
