Mycoblastus
''Mycoblastus'' is a genus of crustose lichens in the family Tephromelataceae. Members of the genus are commonly called blood lichens. Taxonomy The genus was circumscribed in 1852 by Johannes Musaeus Norman, who selected the widespread '' Mycoblastus sanguinarius'' as the type species. This species was one of many introduced by Carl Linnaeus in his influential 1753 work ''Species Plantarum'', as ''Lichen sanguinarius''. In North America this species is colloquially known as the "bloody-heart lichen". In 1984 Josef Hafellner created the family Mycoblastaceae to contain this genus, but this family has since been placed in synonymy with the Tephromelataceae. Description ''Mycoblastus'' species produce a grayish-white or greenish-gray crustose thallus that contains a green algal photobiont from the genus ''Trebouxia''. The apothecia are typically large, hemmispherical, shiny black or dark pigmented, and lack a margin. There are highly branched and anastomosing paraphyses that form ...

Tephromelataceae
The Tephromelataceae are a family of lichenized fungi in the order Lecanorales. The family was circumscribed by Austrian lichenologist Josef Hafellner in 1984. Tephromelataceae comprises the genera '' Tephromela'', '' Calvitimela'', '' Mycoblastus'' and '' Violella'', which together constitute a well-supported monophyletic group. The family Mycoblastaceae, proposed by Hafellner to contain the genus ''Mycoblastus'', was also published in the same 1984 publication; it was later placed into synonymy with Tephromelataceae. The latter name takes precedence because of its first adopted use. Genera Tephromelataceae contains 4 genera and about 53 species. This is a list of the genera contained within the Tephromelataceae; following the genus name is the taxonomic authority In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics.

List Of Common Names Of Lichen Genera
This is a list of common names of lichen genera. When a common name for a lichen genus is the same as the scientific name for that genus, it is not included in the following list. This list only includes genera common names that are widely used, as indicated by the common name either appearing in a peer reviewed scientific publication or in a scientifically reliable reference source. A common name for a lichen genus will often uniquely refer to that genus, but not always. Sometimes the same common name may refer to several different genera, which may not be related by sharing common ancestry. An example is that " wart lichen" refers to at least five different genera in four different families. Sometimes the same genus may have more than one widely used common name. For example, members of the genus ''Staurothele'' are commonly called " wart lichens", and also "rock pimples". Lichen genus common names my come from the shape, color, or other feature of some members of a genus. Other m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascus
An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. ''Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. ''Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some ''Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bourrelet ...

Apothecia
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraphyses
Paraphyses are erect sterile filament-like support structures occurring among the reproductive apparatuses of fungi, ferns, bryophytes and some thallophytes. The singular form of the word is paraphysis. In certain fungi, they are part of the fertile spore-bearing layer. More specifically, paraphyses are sterile filamentous hyphal end cells composing part of the hymenium of Ascomycota and Basidiomycota interspersed among either the asci or basidia respectively, and not sufficiently differentiated to be called cystidia A cystidium (plural cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that ar ..., which are specialized, swollen, often protruding cells. The tips of paraphyses may contain the pigments which colour the hymenium. In ferns and mosses, they are filament-like structures that are found on sporangia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
