Nesolechia (fungus)
''Nesolechia'' is a genus of parasitic fungi in the family Parmeliaceae. All three species in the genus lichenicolous fungi, grow on lichens. ''Nesolechia'' probably evolved from a lichen ancestor, as it is closely related to many lichenized species of fungi. ''Nesolechia'' fungi typically develop gall-like structures on their host (biology), hosts that may be roughly spherical to lobe-like or leafy. Taxonomy The genus was circumscription (taxonomy), circumscribed in 1856 by Italian lichenologist Abramo Bartolommeo Massalongo, with ''Nesolechia oxyspora'' assigned as the type species. It contained species formerly placed in ''Abrothallus'' that produced ascospores without a septum. He also included ''N. inquinans'', ''N. thallicola'', ''N. heeri'', and ''N. punctum'' in the genus; these are now placed in the genera ''Micarea'', ''Phacopsis'', ''Scutula'', and ''Bachmanniomyces'', respectively. In his 1930 work on parasitic fungi, Karl von Keissler included 10 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punctelia Rudecta
''Punctelia rudecta'', commonly known as the rough speckled shield or the speckleback lichen, is a North American species of foliose lichen in the family Parmeliaceae. This species can be readily identified by the light color of the thallus underside, the relatively large lobes at the edges of the thallus, and the tiny white pores present on the top of the thallus that are characteristic of the genus ''Punctelia''. The lichen is quite abundant and widespread in the eastern and southeastern United States, although it also occurs in Canada and northern Mexico, but is less common in these regions. The lichen usually grows on bark, and less commonly on shaded rocks. There are several lookalike ''Punctelia'' species; these can often be distinguished from ''P. rudecta'' by differences in distribution or in the nature of the reproductive structures present on the thallus. Although ''Punctelia rudecta'' was previously thought to have a much more expansive global distribution, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
