Diese Webseite enthält unterschiedliche Angebote für die Identifizierung von Flechten, die auf dem nordamerikanischen Kontinent vorzufinden sind, hierunter beispielsweise weiterführende Literaturvorschläge. Die Seite richtet sich besonders auch an Menschen, die neu mit dieser Beschäftigung anfangen und dementsprechend detailliertere Hilfsvorschläge benötigen. ... [Redaktion vifabio]
Lichenicolous fungi live exclusively on lichens, most commonly as host-specific parasites, but also as broad-spectrum pathogens, saprotrophs or commensals. Over 1800 species have been described throughout the Ascomycota and Basidiomycota, and estimates are that 3000 species will eventually be described (Lawrey and Diederich, 2003). The great majority (over 95%) of described lichenicolous fungi belong to the ascomycetes, representing 19 orders and seven classes. This site contains a systematic listing of all known genera and species of lichenicolous fungi (modified from Lawrey and Diederich, 2003), isolated strains available in major culture collections (with collection accession numbers), and published sequences (with GenBank accession numbers). Literature references are provided for each genus (from Lawrey and Diederich, 2003, with updates). ... [Information of the supplier]
This website will introduce you to the basics of lichens and the aim is to cover a broad range of topics with more than just a superficial account of each. However, the website is not an overly technical one so that a lichen expert will find nothing new here. You don't need any prior knowledge of lichens and the best starting point for someone who knows nothing about lichens is the WHAT IS A LICHEN? page. It gives a short summary of the fundamental facts. Moreover, the links in that page will take you to various other sections for more information about topics that might interest you. This website will not help you identify lichens to species, nor even to genera. There are various printed and electronic sources that will help you in that. ... [Information of the supplier]
This page links to 17 index pages: 16 of them provide links to photos of identified lichens, including those that are identified to genus but not to species. It also links to an index page providing access to about 300 "mystery" lichens that are completely or partially unidentified, and a page that links to topics in lichen natural history. There are about 7,000 photos on the site, illustrating approximately 1,275 species. Most of the photos were taken for the book, Lichens of North America, with text by Dr. Irwin Brodo, published in 2001 by Yale University Press. There are two photos by others. Almost all are from the continental U.S. and Canada, but there are some from Baja California, Mexico, and a few from southern France. ... [Information of the supplier]
Lichenology in Luxembourg and Belgium started in the early XIXth century, but it was especially towards the end of that century that national floras and checklists became available. After 1900, the lichenological exploration dramatically declined in these two countries, and it is only since the beginning of the sixties that, through the work of Prof. Jacques Lambinon, a new era of lichenology started. It is also during that time that Belgian lichenologists started exploring the neighbouring areas of northern France, which are therefore included within the scope of the present checklist. Since the early eighties, we have attempted to fill the gap by preparing a detailed inventory of crustose lichens, as well as of lichenicolous fungi which, although not lichenized, have traditionally been studied by lichenologists. Nowadays, the total number of accepted species almost reaches 1250, more than twice the number of previously published taxa. Nevertheless, no doubt this number will continue to increase in the forthcoming years for several reasons: we know of many, often sterile crusts, that still require identification; several genera are poorly known in the area of study (e. g. Acarospora, Thelidium, Verrucaria); many lichenicolous fungi and some small, inconspicuous crustose lichens are only found by chance, and despite very careful sampling during these past years, many have certainly been missed; comparison with modern European floras or checklists suggests that a relatively large number of additional species might occur in the study area. Therefore the aim of this internet site is to update our current knowledge of lichens and lichenicolous fungi in Luxembourg, Belgium and northern France, and to encourage students and botanists to pay attention to this fascinating world of organisms. ...

This website grew out of the activities of Sylvia and Stephen Sharnoff, who did the photographic fieldwork for the book "Lichens of North America", by Irwin M.Brodo and the Sharnoffs, published in November, 2001 by Yale University Press. For a brief introduction to lichen biology and how lichens interact with the greater environment, you will find the section "Lichen Biology and the Environment". Information about lichens and wildlife, including invertebrates, can be found at "Lichens and Wildlife". For a description of how people have made use of lichens, including an extensive bibliographical database, click on "Lichens and People". Check out the "Useful Links" page for many useful connections to this project and to the world of lichens. ... [Information of the supplier, modified]
This database is a compilation of nine independent databases: Lichen specimens at Bergen Museum, University of Bergen (BG); Lichen specimens at the herbarium of Duke University, North Carolina (DUKE); Lichen specimens at the University of Minnesota Lichen Herbarium, Minnesota (MIN); Lichen specimens at the Botanical Museum, University of Oslo (O); Lichen specimens at the Swedish Museum of Natural History (S); Lichen specimens at Tromsø Museum, University of Tromsø (TROM); Lichen specimens at the Botanical Museum, University of Uppsala (UPS); Lichen specimens in the herbarium of Dr. Håkon Holien, at Nord-Trøndelag College; The Field Note Database at Botanical Museum, Oslo; and The Field Investigation Database at Botanical Museum, Oslo. The data sets consist of nearly all computerized Norwegian specimens identified to species level in the herbaria listed above. ... [Information of the supplier, modified]
This database contains over 29,900 records of documented occurrences of lichens in units of the U. S. National Park System. The records were obtained from the scientific literature, from National Park Service reports, and from the University of Minnesota Herbarium. Unpublished herbarium records from other herbaria are not included because they cannot be cited. Over 530 references reporting almost 2,650 lichen species from 153 park units are included. Only parks with reported lichens are included in the database. We have been unable to locate lichen references for other parks in the National Park system. All lichen names were standardized to Version 13 (2008) of Esslinger's Checklist of North American Lichens. ... [Information of the supplier]
The goal of this page is to provide tools that can contribute for the identification and taxonomy of the genus Parmotrema A. Massal. (lichenized Ascomycota, Parmeliaceae), through short comparative diagnoses and colour images, usually with a quality that enable the zoom on the features of taxonomic importance. You can be combine this page with identification keys, like the excelent Neotropical Keys of Harrie Sipman. A paper with keys, tables and descriptions for some Brazilian species is available. For the species with salazinic acid, you can also consult my thesis. The site was supported in part by funding from the Biodiversity Synthesis Center of the Encyclopedia of Life; Brazilian support by UFMS, FUNDECT and CNPq. ... [Information of the supplier]
Welcome to the largest photo collection of tropical lichens online. You can search this website by typing a few letters in the search box, or browse by clicking the first letter of the genus. Field guides with pictures of tropical lichens are rare although lichen diversity is highest in the tropics. With this website we provide images of many rarely depicted lichen taxa. This website is an initiative of André Aptroot (main image contributor) and Laurens Sparrius (web programming). This website contains over 3800 photos of over 2300 species. ...
