A Checklist of Lichens Collected During the First Howard Crum Bryological Workshop, Delaware Water Gap National Recreation Area
Opuscula Philolichenum, 2: 1-10. 2005. Contributions to the Lichen Flora of Pennsylvania: A Checklist of Lichens Collected During the First Howard Crum Bryological Workshop, Delaware Water Gap National Recreation Area RICHARD C. HARRIS1 & JAMES C. LENDEMER2 ABSTRACT. – A checklist of 209 species of lichens and lichenicolous fungi collected during the First Howard Crum Bryological Workshop in the Delaware Water Gap National Recreation Area, Pennsylvania, USA is provided. The new species Opegrapha bicolor R.C. Harris & Lendemer, collected during the Foray, is described. Chrysothrix flavovirens Tønsberg and Merismatium peregrinum (Flotow) Triebel are reported as new to North America. On April 23-26, 2004, we were graciously allowed to be commensals during the First Howard Crum Bryological Workshop in the Delaware Water Gap National Recreation Area, Pennsylvania, USA. Given the dearth of knowledge of lichen distributions in Pennsylvania and the overall lack of recent vouchers, this was a valuable opportunity to collect in what turned out to be a rich and interesting area. We were quite surprised by the apparent high lichen diversity, as well as the number of novelties and rarities, in an area so close to the East Coast megalopolis. In four half-days in the field, we collected 209 species in a limited area of the Pennsylvania part of the Park. Some are clearly new to science of which, Opegrapha bicolor is described here (see Endnote). Two presumably undescribed species of Fellhanera will be published elsewhere, and the Halecania will be included in a forthcoming treatment of Ozark lichens. Others are left for the future, as present material (and our knowledge) are inadequate. -
A New Checklist of Lichenised, Lichenicolous and Allied Fungi Reported from South Africa
Page 1 of 4 Original Research A new checklist of lichenised, lichenicolous and allied fungi reported from South Africa Author: Background: The last comprehensive list of lichenised, lichenicolous and allied fungi reported 1 Alan M. Fryday from South Africa was published in 1950. A checklist is important to provide basic information Affiliation: on the extent of the diversity, and to provide the most recent name and classification. 1Department of Plant Biology, Michigan State University, Objective: To present a list of all the lichenised, lichenicolous and allied fungi reported from United States South Africa. Correspondence to: Methods: The list presented is entirely literature based and no attempt has been made to Alan Fryday check the report of any taxa or their status by checking the specimens upon which they are based. Firstly, all taxa that were not reported from within the modern boundaries of South Email: Africa were excluded. Next, the Recent literature on lichens database was searched for literature [email protected] on South African lichens since 1945 and all references checked for new species or new reports, Postal address: which were then added to the list. These names were then checked against Index Fungorum Department of Plant Biology, to ensure that the most current name was being used. Finally, the list was rationalised by Plant Biology Laboratories, 612 Wilson Road, East excluding all synonyms and dubious infraspecific taxa. Lansing, MI, 48824, Results: The current list includes 1750 taxa in 260 genera from mainland South Africa, with United States an additional 100 species and 23 genera from the sub-Antarctic Prince Edward Islands, which Dates: are treated separately. -

Rinodina Fuscoisidiata, a New Muscicolous, Isidiate Species from Venezuela
The Lichenologist 42(1): 73–76 (2010) © British Lichen Society, 2009 doi:10.1017/S0024282909990193 Rinodina fuscoisidiata, a new muscicolous, isidiate species from Venezuela Mireia GIRALT, Klaus KALB and John A. ELIX Abstract: Rinodina fuscoisidiata, a muscicolous isidiate species with large isidia and Pachysporaria-type ascospores is described from Venezuela. This species contains an unknown terpene as a major secondary metabolite in addition to traces of atranorin. It is compared with the four known isidiate Rinodina taxa.

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. -
Green-Algal Photobiont Diversity (Trebouxia Spp.) in Representatives of Teloschistaceae (Lecanoromycetes, Lichen-Forming Ascomycetes)
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2014 Green-algal photobiont diversity (Trebouxia spp.) in representatives of Teloschistaceae (Lecanoromycetes, lichen-forming ascomycetes) Nyati, Shyam ; Scherrer, Sandra ; Werth, Silke ; Honegger, Rosmarie Abstract: The green algal photobionts of 12 Xanthoria, seven Xanthomendoza, two Teloschistes species and Josefpoeltia parva (all Teloschistaceae) were analyzed. Xanthoria parietina was sampled on four continents. More than 300 photobiont isolates were brought into sterile culture. The nuclear ribosomal internal transcribed spacer region (nrITS; 101 sequences) and the large subunit of the RuBiSco gene (rbcL; 54 sequences) of either whole lichen DNA or photobiont isolates were phylogenetically analyzed. ITS and rbcL phylogenies were congruent, although some subclades had low bootstrap support. Trebouxia arbori- cola, T. decolorans and closely related, unnamed Trebouxia species, all belonging to clade A, were found as photobionts of Xanthoria species. Xanthomendoza species associated with either T. decolorans (clade A), T. impressa, T. gelatinosa (clade I) or with an unnamed Trebouxia species. Trebouxia gelatinosa genotypes (clade I) were the photobionts of Teloschistes chrysophthalmus, T. hosseusianus and Josefpoel- tia parva. Only weak correlations between distribution patterns of algal genotypes and environmental conditions or geographical location were observed.
