Eschatogonia
''Eschatogonia'' is a genus of lichen-forming fungi in the family Ramalinaceae. It has seven species. The genus was circumscribed by the Italian lichenologist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1853. Description The genus ''Eschatogonia'' includes lichens with a thallus, meaning the body of the lichen is composed of small, scale-like lobes known as . These squamules have a single layer of cortical (outer) tissue on both their upper and lower surfaces. The lichen's , or photosynthetic partner, is a green alga. The apothecia (fruiting bodies) are (directly attached to the surface without a stalk) and lack a , meaning they do not have a rim of thallus-derived tissue around them. The apothecia range in colour from flesh-toned (carneous) to reddish brown. Each ascus An ascus (; : asci) 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eschatogonia Angustiloba
''Eschatogonia angustiloba'' is a species of corticolous (bark-dwelling) squamulose lichen in the family Ramalinaceae. Formally described as a new species in 2008, it is distinguished by its very narrow, thread-like that are typically only 0.1–0.3 mm wide, much narrower than those of the related '' E. prolifera''. It forms loose patches of overlapping scales on tree bark and shows considerable chemical variation, with different populations containing distinct suites of secondary metabolites. The lichen is known from lowland and sub-montane tropical rainforests in Brazil, the Peruvian Amazon and Suriname, where it grows on the lower bark of standing tree trunks in undisturbed forest environments. Taxonomy ''Eschatogonia angustiloba'' is a squamulose (scale-forming) member of the family Ramalinaceae that was formally described as new to science by the Norwegian lichenologist Einar Timdal in 2008. Within the genus, it is most easily distinguished from the widesprea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
