Friedrich Wilhelm Zopf
Friedrich (or Friederich) Wilhelm Zopf (12 December 1846 – 24 June 1909) was a well-known German botanist and mycologist. He dedicated to his whole life with fungal biology, particularly in classification of fungi and dye production in fungi and lichens. Besides, his textbook on fungi called “Die pilze in morphologischer, physiologischer, biologischer und systematischer beziehung (Translation: The mushrooms in morphological, physiological, biological and systematic relationship)” in 1890 was also an outstanding work on the subject for many decades. The unicellular achlorophic microalgae ''Prototheca zopfii'' is named after him because of his profound suggestions and contributions to Krüger's pioneering work in ''Prototheca''. Thus, his numerous contributions gave him a special status in mycological history. Early life Wilhelm Zopf was born in Roßleben in Thuringia in 1846. Before going into biological science area, he has been an elementary school teacher in Thondorf at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichenicolous Fungus
A lichenicolous fungus is a member of a specialised group of fungi that live exclusively on lichens as their host organisms. These fungi, comprising over 2,000 known species across 280 genera, exhibit a wide range of ecological strategies, including parasitism, commensalism, and mutualism. They can be found in diverse environments worldwide, from tropical to polar regions, and play important roles in lichen ecology and biodiversity. Lichenicolous fungi are classified into several taxonomic groups, with the majority belonging to the Ascomycota and a smaller portion to the Basidiomycota. Their interactions with host lichens range from mild parasitism to severe pathogenicity, sometimes causing significant damage to lichen communities. While the study of lichenicolous fungi dates back to the mid-18th century, recent decades have seen significant advancements through modern research methods, including molecular techniques, metagenomics, and sophisticated imaging. These fungi show vary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthoniales
The Arthoniales is the second largest order of mainly crustose lichens, but fruticose lichens are present as well. The order contains around 1500 species, while the largest order with lichenized fungi, the Lecanorales, contains more than 14000 species. Classification The Arthoniales is one of two orders of the class Arthoniomycetes within the phylum Ascomycota. The order includes seven families ( Andreiomycetaceae, Arthoniaceae, Chrysotrichaceae, Lecanographaceae, Opegraphaceae, Roccellaceae and Roccellographaceae). Lecanographaceae, Roccellographaceae, Opegraphaceae and Roccellaceae are well-supported families within Arthoniales, and they were circumscribed in 2011. Andreiomycetaceae was described as a new family by Hodkinson and Lendemer in 2013. The Arthoniales is the sister group to Dothideomycetes. Figure 1.

Arthonia
''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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bryostigma
''Bryostigma'' is a genus of fungi of uncertain familial placement in the order Arthoniales. The genus is characterised by its thin, patchy growth that either partially embeds into its growing surface or forms an irregular, granular surface, with distinctive red or blue iodine staining of its hyphae and very small fruiting bodies. Most ''Bryostigma'' species are parasitic ( lichenicolous), growing on other lichens, though a few species like ''B. lapidicola'' grow independently on stone or moss. While the genus was initially established with a single species growing on moss, it was significantly expanded in 2020 when several species were transferred from the related genus ''Arthonia'' based on DNA analysis, though this taxonomic reclassification has been subject to some scientific dispute. As of 2024, the genus includes seventeen species – thirteen parasitic and four independent lichen species. Taxonomy The genus was circumscribed in 1979 by Josef Poelt and Peter Döbbeler, wi ...

Physcia Caesia
''Physcia caesia'', known colloquially as blue-gray rosette lichen and powder-back lichen, is a species of foliose lichenized fungus. First described by Georg Franz Hoffmann in 1784, it is common across much of Europe, North America and New Zealand, and more patchily distributed in South America, Asia, Australia and Antarctica. There are 2 subspecies: ''P. c. caesia'' and ''P. c. ventosa'', as well as a number of distinct forms and varieties. Molecular studies suggest that the species as currently defined may be polyphyletic. It is typically pale gray shading to darker gray in the center (though some forms are considerably darker), and grows in a small rosette, usually some across at maturity. It only rarely has apothecia, instead reproducing most often vegetatively via soredia, which are piled in round blue-gray mounds across the thallus's upper surface. It grows most often on rock—principally calcareous, but also basaltic and siliceous—and also occurs on bone, bark and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physcia
''Physcia'' is a genus of lichen-forming fungi in the family Physciaceae. The widely distributed genus contains about 80 species. The genus is cosmopolitan distribution, cosmopolitan, and has been extensively studied in various regions in the past several decades, with significant biodiversity in South America identified as a central diversity hotspot. ''Physcia'' species are foliose lichen, foliose, lichens that grow with a loose to close appressed habit. Their upper surface is typically whitish, pale greenish, green-grey, or dark grey in colour. The thallus colour remains relatively unchanged when moistened. ''Physcia'' lichens typically grow corticolous lichen, on bark, corticolous lichen, on wood, or saxicolous lichen, rock, although they have occasionally been recorded dwelling on man-made structures. They thrive in nutrient-rich environments and are expanding rapidly in urban areas of the United Kingdom previously affected by sulfur dioxide, SO2 pollution. The main charac ...

Arthoniomycetes
Arthoniomycetes are a class of ascomycete fungi. It includes two orders: Arthoniales and Lichenostigmatales. Most of the taxa in these orders are tropical and subtropical lichens.

Fungi Of Iceland
A fungus (: fungi , , , or ; 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 one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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'' or ''Eumycete ...
