Lecidea Perlatolica
''Lecidea'' is a genus of crustose lichens with a carbon-black ring or outer margin ( exciple) around the fruiting body disc ( apothecium), usually (or always) found growing on (saxicolous) or in (endolithic An endolith or endolithic is an organism ( archaeon, bacterium, fungus, lichen, algae, sponge, or amoeba) that is able to acquire the necessary resources for growth in the inner part of a rock, mineral, coral, animal shells, or in the pores bet ...) rock.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichens that have such a black exciple are called lecideine, meaning "like ''Lecidea'', even if they are not in this genus. Members of the genus are commonly called disk lichens or tile lichens. Selected species According to the ''Dictionary of the Fungi'' (10th edition, 2008), the widespread genus contains an estimated 427 species. * '' Lecidea atrobrunnea'' * '' Lecidea hassei'' * '' Lecidea keimioeensis'' * '' Lecidea laboriosa'' * ' ...

Lecideaceae
The Lecideaceae are a family (biology), family of lichen-forming fungi in the order Lecideales. It contains about 30 genus, genera and roughly 250 species. A major distinguishing characteristic of the family is the form of the ascomata, fruiting bodies: typically circular, dark, and without a . Most species in the family are lichenised with green algae, although a few species, scattered amongst several genera, are lichenicolous fungus, lichenicolous—they live on other lichens. Lecideaceae lichens tend to grow saxicolous lichen, on rocks, lignicolous lichen, wood, and terricolous lichen, soil. Several Lecideaceae species accelerate the weathering of rock surfaces, a process known as pedogenesis, by extending their hyphae into cracks and expelling rock flakes. This contributes to significantly faster weathering rates in certain environments, impacts various materials from natural rocks to man-made Sekishu roof tiles, and involves key biomolecules identified for survival and bio ...

Lopadiaceae
''Lopadium'' is a genus of lichen-forming fungi in the monotypic family Lopadiaceae, which is in the order Lecideales. The genus contains 12 species. These lichens form thin, crust-like growths made up of fine granules or tiny scale-like flakes and produce small, stalkless disc-shaped reproductive structures that are distinctly narrowed at the base, giving them a pinched appearance. Distinguished by their unusual spore-producing sacs that contain only a single large ascospore instead of the typical eight, ''Lopadium'' species typically colonize decaying plant matter, moss cushions, or bark in cool, humid environments and can be identified microscopically by their unbranched paraphyses with distinctive dark brown swollen tips. Taxonomy ''Lopadium'' was circumscribed by the German lichenologist Gustav Wilhelm Körber in 1855. He assigned '' Lopadium pezizoideum'' as the type species. The family monotypic Lopadiaceae is classified in the order Lecideales. However, according to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichen
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class (biology)
In biological classification, class () is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are domain, kingdom, phylum, order, family, genus, and species, with class ranking between phylum and order. History The class as a distinct rank of biological classification having its own distinctive name – and not just called a ''top-level genus'' ''(genus summum)'' – was first introduced by French botanist Joseph Pitton de Tournefort in the classification of plants that appeared in his '' Eléments de botanique'' of 1694. Insofar as a general definition of a class is available, it has historically been conceived as embracing taxa that combine a distinct ''grade'' of organization—i.e. a 'level of complexity', measured in terms of how differentiated their organ systems are into distinct regions or sub-organs—with a distinct ''type'' of construction, whic ...

Lecanoromycetes
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota.
