A cyanolichen from the Lower Devonian Rhynie chert.
The 400 million-year-old Rhynie chert has provided a wealth of information about various types of fungal interactions that existed in this Early Devonian paleoecosystem. In this paper we report the first unequivocal evidence of a lichen symbiosis from the Rhynie chert. Specimens of a new genus, Winfrenatia, consist of a thallus of superimposed layers of aseptate hyphae and, on the upper surface...
متن کاملMicrobial life in the late Paleozoic: new discoveries from the Early Devonian and Carboniferous
Fungal spores from the Lower Devonian Rhynie Chert are known to harbor a wide variety of parasitic and saprotrophic microfungi. However, only a few of these intrusive organisms have been documented in detail. This paper describes a previously unknown microfungus contained in fungal spores from the Rhynie chert; it consists of tenuous branched filaments and terminal, globose, usually apophysate ...
متن کاملDeciphering interfungal relationships in the 410-million-yr-old Rhynie chert: Morphology and development of vesicle-colonizing microfungi
The intraradical portion of arbuscular mycorrhizal (AM) fungi comprises mycelium, vesicles, and special physiological interfaces termed arbuscules; sometimes mycorrhizal fungi also produce spores within their hosts. Arbuscules are ephemeral structures that collapse after a few days, while the hyphae and vesicles appear to remain intact for some time after arbuscule senescence (post-arbuscule st...
متن کاملThe Rhynie Chert, Scotland, and the search for life on Mars.
Knowledge of ancient terrestrial hydrothermal systems-how they preserve biological information and how this information can be detected-is important in unraveling the history of life on Earth and, perhaps, that of extinct life on Mars. The Rhynie Chert in Scotland was originally deposited as siliceous sinter from Early Devonian hot springs and contains exceptionally well-preserved fossils of so...
متن کاملPalaeoecology and palaeophytogeography of the Rhynie chert plants: further evidence from integrated analysis of in situ and dispersed spores
The remarkably preserved Rhynie chert plants remain pivotal to our understanding of early land plants. The extraordinary anatomical detail they preserve is a consequence of exceptional preservation, by silicification, in the hot-springs environment they inhabited. However, this has prompted questions as to just how typical of early land plants the Rhynie chert plants really are. Some have sugge...
