''Stylonema alsidii'' is a species of marine red algae. The type locality is Trieste in Italy, but it has a worldwide distribution. The species was first described by Giovanni Zanardini in 1840 as ''Bangia alsidii''. Distribution It is one of the algae of the Houtman Abrolhos, found off the coast of Western Australia.

Giovanni Zanardini
Giovanni Antonio Maria Zanardini (12 June 1804, Venice – 24 April 1878) was an Italian physician and botanist who specialized in the field of phycology. In 1831 he obtained his medical doctorate from the University of Padua, followed by a degree in surgery and obstetrics from the University of Pavia three years later. During his career, he worked as a physician in Padua and Venice. For a period of time, he served as secretary of the ''Istituto Veneto Scienze e Lettere''. The algae genus ''Zanardinia'' (in class Phaeophyceae), is named after him, as are species with the epithet of ''zanardinii''.

Pythium Porphyrae
''Pythium porphyrae'', is a parasitism, parasitic species of oomycete in the family Pythiaceae. It is the cause of red rot disease or red wasting disease, also called ' () in Japanese language, Japanese. The Botanical name, specific epithet ''porphyrae'' () stems from the genus of one of its common hosts, ''Porphyra'', and the purple-red color of the lesions on the thallus of the host. However, many of its hosts have been moved from the genus ''Porphyra'' to ''Pyropia''. Economic impact ''Pythium porphyrae'' can destroy an entire crop of nori within 3 weeks.ARASAKI, S. (1962).

Oomycete
Oomycota forms a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms, called oomycetes (). They are filamentous and heterotrophic, and can reproduce both sexually and asexually. Sexual reproduction of an oospore is the result of contact between hyphae of male antheridia and female oogonia; these spores can overwinter and are known as resting spores. Asexual reproduction involves the formation of chlamydospores and sporangia, producing motile zoospores. Oomycetes occupy both saprophytic and pathogenic lifestyles, and include some of the most notorious pathogens of plants, causing devastating diseases such as late blight of potato and sudden oak death. One oomycete, the mycoparasite '' Pythium oligandrum'', is used for biocontrol, attacking plant pathogenic fungi. The oomycetes are also often referred to as water molds (or water moulds), although the water-preferring nature which led to that name is not true of most species, which are terrestrial pathogens. ...

Parasitism
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

Kathleen Mary Drew-Baker
Kathleen Mary Drew-Baker (6 November 1901 – 14 September 1957) was a British phycologist, known for her research on the edible seaweed '' Porphyra laciniata'' (nori), which led to a breakthrough for commercial cultivation.

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...
