Physoderma Bothriochloae
''Physoderma'' is a genus of chytrid fungi. Described by German botanist Karl Friedrich Wilhelm Wallroth in 1833, the genus contains some species that are parasitic on vascular plants, including '' P. alfalfae'' and '' P. maydis'', causative agents of crown wart of alfalfa and brown spot of corn, respectively. Of the chytrid genera, ''Physoderma'' is the oldest.Sparrow FK. 1960. Aquatic phycomycetes. 2nd ed. Ann Arbor, Michigan: University of Michigan Press. However, species were confused with the rust fungi, the genus '' Synchytrium'', and the genus '' Protomyces'' of Ascomycota.Karling, J.S. 1977. Chytridiomycetarum Iconographia. Monticello, New York: Lubrecht & Cramer. Members of ''Physoderma'' are obligate parasites of pteridophytes and angiosperms. There are approximately 80 species within this genus (depending on whether one includes those traditionally belonging to '' Urophlyctis'').

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomyce ...

Anemone
''Anemone'' () is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are commonly called windflowers. They are native to the temperate and subtropical regions of all continents except Australia, New Zealand and Antarctica. The genus is closely related to several other genera including ''Anemonoides'', ''Anemonastrum'', ''Hepatica'', and ''Pulsatilla''. Some botanists include these genera within ''Anemone''. Description ''Anemone'' are perennials that have basal leaves with long leaf-stems that can be upright or prostrate. Leaves are simple or compound with lobed, parted, or undivided leaf blades. The leaf margins are toothed or entire. Flowers with 4–27 sepals are produced singly, in cymes of 2–9 flowers, or in umbels, above a cluster of leaf- or sepal-like bracts. Sepals may be any color. The pistils have one ovule. The flowers have nectaries, but petals are missing in the majority of species. The fruits are ovoid to obovoid shaped ...

Nowakowskiella
''Nowakowskiella'' is the sole genus of fungi in the family ''Nowakowskiellaceae''. The genus was circumscribed by German mycologist Joseph Schröter in 1897, while the family was originally circumscribed by Frederick Kroeber Sparrow in 1942, and then published validly in 2009. The genus name of ''Nowakowskiella'' is in honour of Leon Nowakowski (1847-1918), who was an Polish naturalist and botanist (Algology and Mycology) from Warsau. The genus was published in Nat. Pflanzenfam. (Engler & Prantl) vol.1 (Issue1) on pages 77, 82 and 134 in 1897.

Joseph Schröter
Joseph Schröter (14 March 1837 – 12 December 1894) was a noted German mycologist, doctor and scientist. He wrote several books and texts, and discovered and described many species of flora and fungi. He also spent around fifteen years, from 1871 to 1886, as a military doctor, particularly in the Franco-Prussian War, in places such as Spandau, Rastatt and Breslau, and rising to the rank of colonel. Life In 1855 Schröter chose to study medicine in Breslau, Lower Silesia (Wrocław, Poland since 1945), but in 1856, he transferred to the Friedrich-Wilhelm Academy in Berlin, Prussia (Germany did not unite into a single nation state until 1871). In 1859 he earned his Doctor of Medicine degree. In the same year, he enlisted in the Prussian army, serving as a doctor in the Franco-Prussian war. He occupied this post to the end of the war, in 1871, before being stationed at Spandau, and later Rastatt. For his efforts as a doctor, as well as the various other contributions he made t ...

Chytridiales
Fungi of the order Chytridiales, like other members of its division, may either have a monocentric thallus or a polycentric rhizomycelium. When the ribosomal genes of members classified in this order were first examined using molecular techniques, it was discovered that the order contained some species that were not related. With the culture and characterization of '' Chytridium olla'', the type species of this order, the limits of the Chytridiales were established. The Chytridiales is now monophyletic and species such as '' Polychytrium aggregatum'', '' Chytriomyces angularis'' and '' Cladochytrium replicatum'' have been transferred to other orders.
