Pyrenula Nitida
''Pyrenula nitida'' is a species of crustose lichen belonging to the family Pyrenulaceae. It has a cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The ext ....

Christian Ehrenfried Weigel
Christian Ehrenfried von Weigel (24 May 1748 – 8 August 1831) was a Swedish-born German scientist and, beginning in 1774, a professor of chemistry, pharmacy, botany, and mineralogy at the University of Greifswald. Biography Born in Stralsund, in 1771 he received his medical doctorate from the University of Göttingen, having studied under Johann Christian Erxleben. In 1806, Weigel was ennobled and carried from then on a '' von'' in his name. He became the personal physician of the Swedish royal house two years later. Among other things, Weigel developed a cooling heat exchanger (German ) (1771), which was later improved upon by Justus von Liebig and then became known as the Liebig condenser (). Furthermore, the honeysuckle genus ''Weigela ''Weigela'' is a genus of between six and 38 speciesAll of the species listed in the 'Selected species' section are accepted by The Plant List, but most are still under review, and therefore subject to changes in status. of decid ...

Crustose Lichen
Crustose lichens are lichens that form a crust which strongly adheres to the Substrate (biology), substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichens consists of a cortex (botany), cortex layer, an algal layer, and a medulla. The upper cortex layer is differentiated and is usually pigmented. The algal layer lies beneath the cortex. The medulla fastens the lichen to the substrate and is made up of Fungus, fungal hyphae. The surface of crustose lichens is characterized by branching cracks that periodically close in response to climatic variations such as alternate wetting and drying regimes. Subtypes * Powdery – considered as the simplest subtype due to the absence of an organized thallus. :The thallus appears powdery. :E.g. Genera ''Lepraria'', ''Vezdaea'' * Endolithic – grows inside the rock, usually in interstitial spaces between mineral grains. The :upper cortex is usually d ...

Pyrenulaceae
The Pyrenulaceae are a family of fungi in the order Pyrenulales. The family was first named by German botanist Gottlob Ludwig Rabenhorst in 1870. Species in the family have a widespread distribution, but are especially prevalent in the tropics, where they grow lichenized with green algae The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as ... on bark.

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

List Of Pyrenula Species
The genus '' Pyrenula'' consists of crustose lichens that usually grow on smooth, shaded bark. About 750 taxa have been named in the genus, although the majority of these names have been excluded from the genus as they have been transferred to other genera, or are considered synonyms. In his world key to the ''Pyrenula'' species, published in 2012, André Aptroot accepted 169 species, including 7 not yet formally described. , Species Fungorum accepts 168 species of ''Pyrenula''.
