Hypocenomyce
''Hypocenomyce'' is a genus of lichen-forming fungi in the family Ophioparmaceae. Species in the genus grow on bark and on wood, especially on burned tree stumps and trunks in coniferous forest. ''Hypocenomyce'' lichens are widely distributed in the northern hemisphere. Taxonomy The genus was circumscribed in 1951 by French lichenologist Maurice Choisy to contain the single species '' Hypocenomyce scalaris'', a lichen that was first formally described by Erik Acharius in 1795. Choisy's original concept of the genus featured a squamulose thallus, adnate apothecia of the lecideine type (i.e., lacking algae and an amphithecium, with a black carbonized margin as in the genus ''Lecidea'') and pycnoconidia that are short, straight, and cylindrical. Norwegian lichenologist Einer Timdal revised the genus in 1984, describing two new species to bring the total ''Hypocenomyce '' species up to ten. Since then, two new species have been described, and several have been transferred to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hypocenomyce Tinderryensis
''Hypocenomyce tinderryensis'' is a species of crustose lichen in the family Ophioparmaceae. It was described as a new species in 2007 by Australian lichenologist John Alan Elix. The type was collected in Tinderry Range in New South Wales, for which it is named. There it was found growing on a dead '' Eucalyptus'' trunk at an elevation of . It somewhat resembles the type species of ''Hypocenomyce ''Hypocenomyce'' is a genus of lichen-forming fungi in the family Ophioparmaceae.

Carbonicola (lichen)
''Carbonicola'' is a small genus of lichen-forming fungi. It is the sole genus in the monogeneric family Carbonicolaceae. The genus, which collectively has an almost cosmopolitan distribution, contains three squamulose lichens that prefer to grow on burned wood in temperate areas of the world. Taxonomy Both the genus and the family were circumscribed in 2013 by Mika Bendiksby and Ernst Timdal. In a reassessment of the genus ''Hypocenomyce'', they found that the genus–as then circumscribed–was polyphyletic, dividable into seven clades belonging to different genera, families, orders and even subclasses. ''Carbonicola'' includes the three species formerly included in the ''Hypocenomyce anthracophila'' group. Using molecular phylogenetic analysis, genus ''Carbonicola'' was shown outside to lie outside the Lecanoraceae, in a sister group position to a clade containing the Cladoniaceae and Stereocaulaceae. The generic name ''Carbonicola'' combines the Latin roots ''carbo'' ("ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 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 organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Species Group
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] |
