Eugène Mayor
Eugène Mayor (7 June 1877, Neuchâtel – 14 September 1976, Neuchâtel) was a Swiss physician and mycologist known for his research on parasitic microfungi. After graduating in medicine from Geneva in 1906, he gained international recognition through his 1910 scientific expedition to Colombia with Otto Fuhrmann, which resulted in the discovery of 126 new fungal species. He served as a physician at the cantonal hospice of Perreux-sur-Boudry from 1913 to 1942, after which he continued his mycological research at the University of Neuchâtel, ultimately publishing nearly 120 scientific works. Early life and career Eugène Mayor was born in Neuchâtel, Switzerland. He studied medicine in Geneva, graduating in 1906, and initially developed an interest in natural sciences, particularly ornithology and later mycology. His introduction to microscopic fungi came through pastor Denis Cruchet. Throughout his life, he maintained an intense focus on parasitic microfungi, conducting de ...

Rust (fungus)
Rusts are fungal plant pathogens of the order Pucciniales (previously known as Uredinales) causing plant fungal diseases. An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus ''Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be microbial culture, grown easily in pure culture. Most species of rust fungi are able to Heteroecious, infect two different plant hosts in different stages of their life cycle, and may produce up to five Morphology (biology), morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinium, uredinia, Telium, telia, and basidia in successive stages of reproduction. Each spore type is very host-specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Languedoc
The Province of Languedoc (, , ; ) is a former province of France. Most of its territory is now contained in the modern-day region of Occitanie in Southern France. Its capital city was Toulouse. It had an area of approximately . History The Roman province of Gallia Narbonensis fell to the Visigothic Kingdom from the 5th to the 8th centuries. Occupied briefly by the Emirate of Córdoba between 719 and 759, it was conquered and incorporated into the Kingdom of the Franks by Pepin the Short in 759 following the Siege of Narbonne.

He visited the region in 1214 seeking the restoration of those lands. In the 13th century, the See of Rome challenged the area's spiritual beliefs, ...

Microfungi
Microfungi or micromycetes are fungi—eukaryotic organisms such as molds, mildews and rusts—which have microscopic spore-producing structures. They exhibit tube tip-growth and have cell walls composed of chitin, a polymer of ''N''-acetylglucosamine. Microfungi are a paraphyletic group, distinguished from macrofungi only by the absence of a large, multicellular fruiting body. They are ubiquitous in all terrestrial and freshwater and marine environments, and grow in plants, soil, water, insects, cattle rumens, hair, and skin. Most of the fungal body consists of microscopic threads, called hyphae, extending through the substrate in which it grows. The mycelia of microfungi produce spores that are carried by the air, spreading the fungus. Many microfungi species are benign, existing as soil saprotrophs, for example, largely unobserved by humans. Many thousands of microfungal species occur in lichens, forming symbiotic relationships with algae. Other microfungi, such as those of ...

Cryptogam
A cryptogam (scientific name ''Cryptogamae'') is a plant, in the broad sense of the word, or a plant-like organism that share similar characteristics, such as being multicellular, photosynthetic, and primarily immobile, that reproduces via spores rather than through flowers or seeds. This broader definition can include algae, fungi, and certain bacteria (like cyanobacteria), even though they may belong to different biological kingdoms. Taxonomy The name ''Cryptogamae'' () means "hidden reproduction", meaning non-seed bearing plants. Other names, such as "thallophytes", "lower plants", and "spore plants" have occasionally been used. As a group, Cryptogamae are paired with the Phanerogamae or Spermatophyta, the seed plants. At one time, the cryptogams were formally recognised as a group within the plant kingdom. In his system for classification of all known plants and animals, Carl Linnaeus (1707–1778) divided the plant kingdom into 24 classes, one of which was the ...
