Megaspora Iranica
''Megaspora'' is a genus of lichen-forming fungi in the family Megasporaceae. It contains four species of crustose lichens that typically grow on soil, bryophytes (mosses and liverworts), or plant litter on chalky . Taxonomy The genus was circumscription (taxonomy), circumscribed by Georges Clauzade and Claude Roux in 1984 with ''Megaspora verrucosa, M. verrucosa'' assigned as the type species. In 2012, Linda in Arcadia and Anders Nordin proposed to conserved name, conserve the name ''Megaspora verrucosa'' against ''M. verrucosa'' due to taxonomic confusion stemming from historical errors in the original basionym citation. The original introduction of ''Aspicilia'' subg. ''Megaspora'' erroneously cited ''Lecanora verrucosa'' as the basionym, when it should have been ''Urceolaria verrucosa'' This misattribution led to the invalid introduction of the name ''Megaspora verrucosa'' by Hafellner & Wirth based on the wrong species. To rectify this and prevent future taxono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thallus
Thallus (: 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. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. 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, thalloidal, thalliform, thalline, or thallose. 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
