Pilocarpaceae
The Pilocarpaceae are a family of crustose lichens in the order Lecanorales. The species of this family have a cosmopolitan distribution and have been found in a variety of climatic regions. Pilocarpaceae was circumscribed by Alexander Zahlbruckner in Adolf Engler's influential 1905 work '' Die Natürlichen Pflanzenfamilien''. In 2004, the family Micareaceae included the genera; '' Helocarpon'', '' Micarea'', ''Psilolechia'', '' Roccellinastrum'', and ''Scutula''. Then in 2005, molecular phylogeny based on mitochondrial rDNA sequences showed that the genus ''Helocarpon'' was not related to the ''Micareaceae'' family and the rest of the genus were related to the Pilocarpaceae family and other genera. Description Pilocarpaceae species are crustose and have ascomata in the form of an brightly-coloured apothecium with a poorly-developed margin comprising loosely-intertwined hyphae. The ascospores are hyaline and often elongated with one or more septa. Genera Pilocarpaceae contains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micarea
''Micarea'' is a genus of lichen-forming fungi in the family Pilocarpaceae. The widely distributed genus contains 142 species and new species are described actively. Species in the genus are crustose lichens and their photobiont (the non-fungal organism) is a single-celled Green algae, green alga. Taxonomy ''Micarea'' was circumscription (taxonomy), circumscribed by Elias Magnus Fries in his 1825 work ''Systema Orbis Vegetabilis''. There have been some taxonomy (biology), taxonomic disputes about the genus. Nowadays, the genus is accepted, although it is Paraphyly, paraphyletic and in need of further research. ''Micarea prasina'' is the type species of the genus. Reproduction Lichenized fungi have developed diverse reproduction strategies. The microlichen genus ''Micarea'' is an excellent model for studying the effects of reproductive traits and environmental factors on speciation because it shows intricate variation in substrate requirements and reproduction modes.
