Hafellner
Josef Hafellner (1951– ) is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus ''Karschia''. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work ''Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae'' has been described as "probably the single most influential publication in lichen systematics in ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichenicolous Fungus
A lichenicolous fungus is a parasitic fungus that only lives on lichen as the host. A lichenicolous fungus is not the same as the fungus that is the component of the lichen, which is known as a lichenized fungus. They are most commonly specific to a given fungus as the host, but they also include a wide range of pathogens, saprotrophs, and commensals. It is estimated there are 3000 species of lichenicolous fungi. More than 1800 species are already described among the Ascomycota and Basidiomycota.Lichenicolous Fungi: Interactions, Evolution, and Biodiversity, Lawrey, James D.; Diederich, Paul. The Bryologist 106(1), pp. 80 120, 2003/ref> More than 95% of lichenicolous fungi described as of 2003 are ascomycetes, in 7 classes and 19 orders Order, ORDER or Orders may refer to: * Categorization, the process in which ideas and objects are recognized, differentiated, and understood * Heterarchy, a system of organization wherein the elements have the potential to be ranked a number o ...

Verrucariaceae
The Verrucariaceae are a family of mostly lichenised fungi in the order Verrucariales. The lichen-forming species, which comprise the vast majority of the family, have a wide variety of thallus forms, and include crustose (crust-like), foliose (bushy), and squamulose (scaly) representatives. Several characteristics of the spore-bearing structures, the ascomata, define the family, including their perithecioid form–more or less spherical or flask-shaped, with a single opening and otherwise completely enclosed by a wall. Squamulose members of the Verrucariaceae with simple ascospores (lacking partitions called septa), and without algae in the spore-bearing region are known as lichens; there are more than 80 of these species. The family has several dozen lichenicolous (lichen-dwelling) examples, including a few genera that contain solely lichenicolous members. An unusually diverse variety of photobiont partners have been recorded, mostly green algae, but also brown algae and yel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Host (biology)
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasitic, a mutualistic, or a commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cells harbouring pathogenic (disease-causing) viruses, a bean plant hosting mutualistic (helpful) nitrogen-fixing bacteria. More specifically in botany, a host plant supplies food resources to micropredators, which have an evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an association is much larger than the other, it is generally known as the host. In parasitism, the parasite benefits ...

Thallus
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or " twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts ( leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoid ...

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.

Verrucariales
Verrucariales is an order (biology), order of Ascomycota, ascomycetous fungi within the subclass Chaetothyriomycetidae of the class Eurotiomycetes. Although most of the Verrucariales are lichenised, the family Sarcopyreniaceae consists of 11 species of lichenicolous fungi, lichenicolous (lichen-dwelling) fungi. Phylogenomics, Phylogenomic analysis suggests that the divergent evolution, divergence between the lichenized Verrucariales and nonlichenized Chaetothyriales occurred about 131 million years ago. Genera of uncertain placement There are some genera in the Verrucariales that have not been placed incertae sedis, with certainty into any family. These are: *''Botryolepraria'' – 2 spp. *''Gemmaspora'' – 1 sp. *''Kalbiana'' – 1 sp. *''Merismatium'' – 10 spp. References Verrucariales, Ascomycota orders Lichen orders Taxa named by David Leslie Hawksworth {{Eurotiomycetes-stub ...

Fungi Described In 1855
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'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Of India
India is home to a large variety of wildlife. It is a biodiversity hotspot with its various ecosystems ranging from the Himalayas in the north to the evergreen rain forests in the south, the sands of the west to the marshy mangroves of the east. India lies within the Indomalayan realm and is the home to about 7.6% of mammal, 14.7% of amphibian, 6% of bird, 6.2% of reptilian, and 6.2% of flowering plant species.Indira Gandhi Conservation Monitoring Centre (IGCMC), New Delhi and thUnited Nations Environmental Programme (UNEP), World Conservation Monitoring Centre Cambridge, UK. 2001/ref> India's forest lands nurture about 500 species of mammals and more than 2000 bird species.
