Pier Luigi Nimis Towards a checklist of Mediterranean lichens Introduction Activity between 1989-1993 Activity after 1993 Delimitation of the "Mediterranean" region ... References Abstract Nimis, P.L.: Towards a checklist of Mediterranean lichens. - Bocconea 6: 5 - 17. 1996 - ISSN 1120-4060. The OPTIMA Commission For Lichens is supporting an international project for a compilation of a general checklist of lichens of the Mediterranean region. This paper describes the history of the project and the present State of the Art, with some critical considerations about the delimitation of the Mediterranean area for a lichen checklist, and a short outline of the main phytogeographic features of southern Europe, as far as lichens are concerned. It is suggested that the national checklist produced in the framework of the project should become available on the Internet, with a possibility of continuous updating by the international lichenological community. Introduction In the last years, mainly as a consequence of the UNESCO Conference of Rio and of the associated increase in research funding, biodiversity has become

Leaves - oblong to oval, rounded at tips, inrolled at sides. Sporophytes - uncommon; stalks red to yellowish, 2 - 4 cm tall; capsules cylindrical, 2 - 3 mm long, horizontal. Habitat In most forested habitats; particularly abundant in dry forests; uncommon in exposed areas; widespread and abundant across Northwestern Ontario's boreal forest; circumpolar. Notes Pleurozium comes from the Latin pleuro, meaning 'ribs', and presumable refers to the arrangement of the branches on either side of the stem that resembles a rib cage. This species is named in honour of J.C. Schreber, a German botanist. Return to Top of Page Home Forest Capital of Canada About Our Website ... Site Map

It is the name of a little Venezuelan island in the Caribbean Sea (South America). You can see the location in a map below. There are four species of Roccella in Venezuela: R. caribaea, R. verruculosa, R. fucoides, and R. babingtonii . Often, they live in rocks near the coast.

Letharia columbiana, in the previous portrait, is its sister species. This was the most widely used dye lichen for indigenous peoples in western North America, used from the Rockies to the Pacific coast, from California to Alaska. Some groups also made paint from it. This lichen is sufficiently poisonous that the Achomawi in Northern California used it to make poison arrowheads, but the Okanagan-Colville made a weak tea of it to treat internal problems, and it was a Blackfoot remedy for stomach disorders. next portrait previous portrait

Lichens are very responsive to environmental stressors in forests, including changes in forest structure, air quality, and climate.

93. North American Lichen Checklist List of cumulative updates to the most recently published North American checklist by Esslinger and Egan (1995). http://www.ndsu.nodak.edu/instruct/esslinge/chcklst/chcklst7.htm

A Cumulative Checklist for the Lichen-forming, Lichenicolous and Allied Fungi of the Continental United States and Canada This checklist consists of cumulative updates to the most recently published North American checklist by Esslinger and Egan (1995). The style and conventions for listings used there are also generally followed here. As in the published checklist, under each genus the accepted names are given first and are in boldface . Names considered to be synonyms are given in normal font only. Significant changes made since the previous online version are given in blue font . As before, the following symbols are used to indicate the lichenicolous fungi and other allied fungi: * = lichenicolous fungi (parasites on living lichens) + = saprophytic fungi related to either lichens or lichenicolous fungi # = various fungi of uncertain status: i.e., those which are questionably or weakly lichen-forming; or algicolous/saprophytic; or parasitic when young but saprophytic or lichen-forming when mature; or lichenicolous lichens. This list is updated at semi-regular intervals, usually about once each year, as changes accumulate in the literature. My purpose for putting this checklist on-line is twofold. First, to provide users of the checklist with the most current updates and changes, and second, to provide the opportunity for (indeed, to

Cryptothecia rubrocincta , the Christmas Lichen Tom Volk's Fungus of the Month for December 2006 Please click TomVolkFungi.net for the rest of Tom Volk's pages on fungi For a Christmas treat, click here for "Fungi that are necessary for a merry Christmas." This month's fungus is a beautiful lichen found on the Gulf Coast of the United States, down thorough Mexico and Central America and into the tropics of South America. It can also be found on the coastal plain of Florida up through North Carolina. Cryptothecia rubrocincta is commonly called the Christmas lichen due to its spectacular red and green color. The red color often encircles the thallus of the lichen, like a wreath. In fact the epithet " rubrocincta " means "red wreath." Sometimes this species is called the Christmas wreath lichen. It's really one of the most spectacular lichens to see. A lichen is a mutualistic relationship between a fungus (the mycobiont) and an alga or a cyanobacterium (the photobiont). The photobiont provides the fungal partner with sugars from photosynthesis, while the mycobiont provides protection from the environment for the alga or cyanobacterium. This symbiosis allows the lichen to grow in very inhospitable environments, such as on exposed rocks and gravestones. The Christmas lichen is typically found on the sides of trees in open areas that get a lot of sunlight, often in an area where there are lots of palmetto. I'll have more to say about that kind of area later. There are perhaps 15,000 species of lichens, almost all of them Ascomycota. Lichenized fungi can be found in 16 orders, 5 of which are entirely composed of lichen-forming fungi. The fungus determines the form of the lichen. Usually reproduction of the fungal partner can be seen with small cups called apothecia, but sexual reproduction is unknown in
