Menegazzia Williamsii
''Menegazzia williamsii'' is a species of foliose lichen in the family Parmeliaceae. Found in New South Wales, Australia, it was described as a new species in 2019 by lichenologist Gintaras Kantvilas. Taxonomy The type specimen was collected from Point Lookout (New England), at an altitude of . Here it was found growing in scrub on twigs of ''Banksia integrifolia'' subsp. ''compar''. The lichen is only known to occur in this area, where it grows as an epiphyte on twigs, branches, and trunks in wet scrub and forest dominated by sclerophyll. It also occurs in rainforest dominated by Antarctic beech (''Nothofagus moorei''). The specific epithet honours Australian botanist John Beaumont Williams, "who co-collected some of the material on which the description is based and had an intimate knowledge of the botany of the New England region of northern New South Wales". Description The main characteristics of ''Menegazzia williamsii'' are an inflated and fragile thallus lacking sore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Lemnoideae, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Menegazzia Pertransita
''Menegazzia pertransita'' is a species of foliose lichen in the large lichen family Parmeliaceae. It is found in New Zealand, Australia, and South America. The lichen was first formally described by Scottish physician and bryologist James Stirton in 1877 as ''Parmelia pertransita''. Swedish lichenologist Rolf Santesson transferred it to the genus ''Menegazzia ''Menegazzia'' is a genus of lichenized fungi containing roughly 70 accepted species.Galloway, D.J. (2007).

Menegazzia
''Menegazzia'' is a genus of lichenized fungi containing roughly 70 accepted species.Galloway, D.J. (2007). Flora of New Zealand - ''Menegazzia'' http://floraseries.landcareresearch.co.nz/pages/index.aspx The group is sometimes referred to as the tree flutes, honeycombed lichens, or hole-punch lichens. The most obvious morphological feature of the genus is the distinctive perforations spread across the upper side of the thallus. This makes the group easy to recognise, even for those not particularly familiar with lichen identification. The genus has a sub-cosmopolitan distribution (excluding Antarctica), but is concentrated in Australasia, Melanesia, and southern South America. Most species grow exclusively on trees, but some grow on rocks, moss, and/or soil. Etymology ''Menegazzia'' was described by the Veronese lichenologist Abramo Massalongo in 1854.James, P.W. and Galloway, D.J. (1992).

Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia (basidiomycetes) or paraphyses (ascomycetes). Cystidia are often important for microscopic identification. The subhymenium consists of the supportive hyphae from which the cells of the hymenium grow, beneath which is the hymenophoral trama, the hyphae that make up the mass of the hymenophore. The position of the hymenium is traditionally the first characteristic used in the classification and identification of mushrooms. Below are some examples of the diverse types which exist among the macroscopic Basidiomycota and Ascomycota. * In agarics, the hymenium is on the vertical faces of the gills. * In boletes and polypores, it is in a spongy mass of downward-pointing tubes. * In puffballs, ...

Ascospore
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 ...
