Lecania Juniperi
''Lecania juniperi'' is a rare species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae. Discovered on ''Juniperus phoenicea'' shrubs in the coastal region of Portugal, it was formally described as a new species in 2012. Despite its resemblance to ''Lecania cyrtella'', ''L. juniperi'' stands out due to its warted and sorediate thallus, larger , and distinct s. Taxonomy ''Lecania juniperi'' was first described by Dutch lichenologist Pieter van den Boom as a new species in 2012. The type specimen was discovered in the Algarve region of Portugal, near Odeceixe, on a ''Juniperus phoenicea'' shrub. The species name ''juniperi'' is derived from the host genus of the lichen. Description The thallus of ''Lecania juniperi'' is corticolous, measuring approximately 1 cm wide and up to 0.5 mm thick. The range in colour from pale grey to greyish brown, and the upper surface can be smooth or prominently warted. The can reach up to 0.8&n ...

Corticolous Lichen
A corticolous lichen is a lichen that grows on bark.Alan Silverside's Lichen Glossary (a-f), Alan Silverside/ref> This is contrasted with lignicolous lichen, which grows on wood that has had the bark stripped from it,Alan Silverside's Lichen Glossary (g-o), Alan Silverside/ref> and saxicolous lichen, which grows on rock.Alan Silverside's Lichen Glossary (p-z), Alan Silverside/ref> Examples of corticolous lichens include the crustose lichen ''Graphis plumierae'', foliose lichen ''Melanohalea subolivacea'' and the fruticose ''Bryoria fuscescens ''Bryoria fuscescens'' is a species of lichen of the family Parmeliaceae.

Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue. *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscular sep ...

Lecanora
''Lecanora'' is a genus of lichen commonly called rim lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichens in the genus ''Squamarina'' are also called rim lichens. Members of the genus have roughly circular fruiting discs (apothecia) with rims that have photosynthetic tissue similar to that of the nonfruiting part of the lichen body (thallus). Other lichens with apothecia having margins made of thallus-like tissue are called lecanorine. ''Lecanora'' has a crustose thallus, trebouxoid photobiont, colourless ascospores and crystals in the amphitecium. It is in the family Lecanoraceae in the suborder Lecanorineae.

Diploicia Canescens
''Diploicia canescens'' is a widespread species of lichenized fungus. It is found throughout much of the world, occurring on every continent except Antarctica. Taxonomy ''Diploicia canescens'' was first described by James Dickson in 1785 as ''Lichen canescens''. It was later assigned to a host of genera before being moved to its current genus, ''Diploicia'', by Abramo Bartolommeo Massalongo in 1852. It is the type species for the genus. Some mycologists assign this species (and all other members of the genus ''Diploicia'') to the genus ''Diplotomma'', but genetic analysis suggests that this would make ''Diplotomma'' a polyphyletic group, and that the ''Diploicia'' species are more appropriately assigned to a separate genus. There are two subspecies, ''D. c. canescens'' and ''D. c. australasica'', which differ in the chemistry of their thallus. ''D. c. canescens'' contains canesolide and buellolide, while ''D. c. australasica'' does not. The genus name ''Diploicia'' derives from ...

Caloplaca Chrysophthalma
''Caloplaca'' is a lichen genus comprising a number of distinct species. Members of the genus are commonly called firedot lichen, jewel lichen.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, gold lichens, "orange lichens", but they are not always orange, as in the case of '' C. albovariegata''. The distribution of this lichen genus is worldwide, extending from Antarctica to the high Arctic. It includes a portion of northern North America and the Russian High Arctic. There are about thirty species of ''Caloplaca'' in the flora of the British Isles. An example species in this genus is '' Caloplaca saxicola'', a lichen with worldwide distribution including the Antarctic continent, Europe and northern North America including the northern reaches of the Canadian boreal forests. A new species of ''Caloplaca'', '' C. obamae'', the first species to be named in honor of Barack Obama, was discovered in 2007 on Santa Rosa Island in California a ...

Lecania Leprosa
''Lecania leprosa'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Ramalinaceae. It occurs in Eastern Europe. Taxonomy The lichen was formally described as a new species in 2008 by Rikke Reese Næsborg and Jan Vondrák. The type specimen was collected from Devín (Carpathian Mountains, Slovakia), where it was found growing on the mortar of a northwest-exposed wall. The species epithet ''leprosa'' means "scurfy" or "scaley", and refers to the form of the lichen thallus. Description ''Lecania leprosa'' has an irregularly areolate, relatively thick crust-like thallus with a colour ranging from pale grey, grey, lead-grey, blue-grey, brown-grey, to dark grey (sometimes with a greenish tint). The species is usually encountered in the sterile form (i.e., without any apothecia), but in the few instances that apothecia have been recorded, they are typically 0.31–0.47 mm in diameter with a brown to dark brown disc and a margin that is the same ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
