Candelariella Ahtii
''Candelariella'' is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with '' Candelariella vitellina'' assigned as the type species. Characteristics The key feature of ''Candelariella'' species are the distinct yellow apothecia. Although all species are very small, even the smallest can be identified by the lemon-yellow to orange-yellow discs. Most species have a yellow thallus, although '' Candelariella antennaria'' is one example with a grey thallus. Some species are pycnidiate. This genus will generally have all spot tests emerge as negative, although K tests may have an orange or reddish colour on some species' apothecia. Spore count between species varies from 8 to 32 simply or thinly septate spores. Spores often hold one to two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Septate
In biology, a septum (Latin for ''something that encloses''; 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 * Penile septum, a fibrous wall between the two corpora cavernosa penis * Septum glandis, ...

Zwackhiomyces Lecanorae
''Zwackhiomyces'' is a genus of lichenicolous (lichen-dwelling) fungi in the family Xanthopyreniaceae. Taxonomy The genus was circumscribed by Martin Grube and Josef Hafellner in 1990, with '' Zwackhiomyces coepulonus'' assigned as the type species. The name ''Zwackhiomyces'' honours the German mycologist Philipp Franz Wilhelm von Zwackh-Holzhausen (1826–1903). ''Zwackhiomyces'' was established to accommodate several lichenicolous fungi previously classified within the collective genus ''Didymella''. The establishment of this new genus was based on several distinguishing morphological characteristics, particularly the structure of the , asci, and , which set it apart from ''Didymella'' and related genera. The genus was placed in the family Arthopyreniaceae within the Dothideales. When first described, the genus included nine species, all of which are parasitic or parasymbiotic on lichens containing green algae as . Three species were described as new: '' Z. euplocinus'' ...

Lichenochora Arctica
''Lichenochora'' is a genus of fungi in the family Phyllachoraceae. It has 44 species. All species in the genus are lichenicolous, meaning they grow parasitically on lichens. The genus was circumscribed by Josef Hafellner in 1989, with '' Lichenochora thallina'' assigned as the type species. Description ''Lichenochora'' fungi form tiny, flask-shaped reproductive structures called perithecia that are typically 0.15-0.3 mm in diameter. The perithecia are embedded within small swellings or galls that they cause to form in their host lichen's body (thallus). Only the dark-coloured openings of these structures are visible on the surface. The walls of the perithecia are brown in colour and made up of several layers of flattened cells. Inside each perithecium are microscopic sac-like structures called asci, which contain the fungal spores. A distinctive feature of ''Lichenochora'' is that each ascus contains either four or eight spores, depending on the species. The spores them ...

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.

Arthonia Almquistii
''Arthonia'' is a genus of lichens in the family Arthoniaceae. It was circumscribed by Swedish botanist Erik Acharius in 1806. It is a genus of thin crustose lichen of widely varying forms, commonly called comma lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Description ''Arthonia'' species are typically crustose lichens, forming thin, often inconspicuous patches that can be either flush with the surface () or sitting on top (superficial). The thallus—the main body of the lichen—may spread without clear boundaries or sometimes be neatly outlined by thin brown lines. In some species, the thallus may be absent altogether. Under chemical tests, the fungal filaments (hyphae) in the thallus can show distinctive reactions, turning red or pale blue when stained with iodine (I+) and then blue with a potassium iodine (K/I) solution. The photosynthetic partner () is most commonly a green alga belonging to the genus '' Trentepohlia''. In so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcogyne Sphaeospora
''Sarcogyne'' is a genus of crustose lichens in the family Acarosporaceae. It was circumscribed by German botanist Julius von Flotow in 1850. A proposal has been put forth in 2021 to assign '' Sarcogyne clavus'' as the type species of the genus, "as it represents the original concept of Sarcogyne as having melanized lecideine apothecia without algae in the margin". Description Genus ''Sarcogyne'' includes lichens with a crust-like (crustose) thallus that can be cracked into small, island-like sections called , which are either broadly attached or have a thick fungal base. Sometimes, the thallus is , meaning it has small, scale-like structures with a stalk less than half the width of the scale. The upper surface, or , of these lichens can vary from absent to quite thick and often gives the lichen a shiny appearance, especially in species found in dry or hot habitats. This shiny layer is particularly common in xerothermic or arid environments. The cortex, which forms the outer la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
