Rusavskia Indochinensis
''Rusavskia indochinensis'' is a species of saxicolous (rock-dwelling) lichen in the family Teloschistaceae. It occurs in India and China. Taxonomy ''Rusavskia indochinensis'' was described as a new species in 2020 by lichenologists Sergey Kondratyuk, Gaurav Kumar Mishra, Sanjeeva Nayaka, and Dalip Kumar Upreti. The species epithet ''indochinensis'' refers to the southern part of the Asian continent, which is where this species has been identified. The type specimen was collected in India, specifically in Uttarakhand's Chamoli district, before Malari on the way to Niti at an altitude of . While ''Rusavskia indochinensis'' is categorically part of the ''Rusavskia'' branch based on its Internal transcribed spacer nrDNA phylogeny, its resemblance to species of the genus ''Zeroviella'' suggests the need for more molecular data for precise classification. Chinese specimens, in particular, require further molecular examination to determine their exact status. Description The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanjeeva Nayaka
Sanjeeva Nayaka (Hindi: संजीव नायक; Kannada: ಸಂಜೀವ ನಾಯಕ) is an Indian lichenologist. He is Senior Principal Scientist at CSIR-National Botanical Research Institute (CSIR-NBRI), Lucknow. He is in charge of the lichenology laboratory. He serves as managing editor of the journal ''Cryptogam Biodiversity and Assessment'', and editor of ''ILS eLetters,'' both published by the Indian Lichenological Society. Career Nayaka was introduced to research during his graduate studies. He was a volunteer in the 'Western Ghats Biodiversity Inventory Programme'. He was awarded with a Summer Research Fellowship of Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore to study the lichens of Bangalore under Madhav Gadgil. After his post-graduation Nayaka moved to Lucknow to work with Dr. D.K. Upreti at CSIR-NBRI. Initially he worked as a project assistant on the All-India Coordinated Project on Taxonomy. During this period, he explored lichens ... [...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] |

Teloschistales
The Teloschistales are an order of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. According to one 2008 estimate, the order contains 5 families, 66 genera, and 1954 species. The predominant photobiont partners for the Teloschistales are green algae from the genera ''Trebouxia'' and '' Asterochloris''. Families *Brigantiaeaceae *Letrouitiaceae *Megalosporaceae *Teloschistaceae The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota.

Siliceous Rock
Siliceous rocks are sedimentary rocks that have silica (SiO2) as the principal constituent. The most common siliceous rock is chert; other types include diatomite. They commonly form from silica-secreting organisms such as radiolarians, diatoms, or some types of sponges Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through .... References Sedimentary rocks {{Petrology-stub ...

Zeroviella Papillifera
''Zeroviella'' is a genus of lichen-forming fungi in the subfamily Xanthorioideae of the family Teloschistaceae. It has eight saxicolous (rock-dwelling) species. ''Zeroviella'' was segregated from '' Rusavskia'', a closely related genus, in 2015. Taxonomy The genus was circumscribed by lichenologists Sergey Kondratyuk and Jae-Seoun Hur in 2015, to contain the species complex centred around ''Rusavskia papillifera''. Accordingly, '' Zeroviella papillifera'' was assigned as the type species of the genus. According to their phylogenetic analysis, these species formed a monophyletic branch, warranting distinction as a new genus. Members of the genus ''Zeroviella'' exhibit distinct differences from those of the genus '' Rusavskia''. Notably, ''Zeroviella'' has cortical layers throughout the thallus, in contrast to ''Rusavskia'', which primarily features tissue with only a slight paraplectenchymatous layer. Additionally, the s of ''Zeroviella'' are noticeably thinner, attributed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
