Physoderma Aeschynomenes
''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''). Taxonomic history The genus was erected in 1833 on the basis of resting spore de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteridophyte
A pteridophyte is a vascular plant (with xylem and phloem) that reproduces by means of spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as " cryptogams", meaning that their means of reproduction is hidden. They are also the ancestors of the plants we see today. Ferns, horsetails (often treated as ferns), and lycophytes ( clubmosses, spikemosses, and quillworts) are all pteridophytes. However, they do not form a monophyletic group because ferns (and horsetails) are more closely related to seed plants than to lycophytes. "Pteridophyta" is thus no longer a widely accepted taxon, but the term ''pteridophyte'' remains in common parlance, as do ''pteridology'' and ''pteridologist'' as a science and its practitioner, for example by the International Association of Pteridologists and the Pteridophyte Phylogeny Group. Etymology The name ''Pteridophyte'' is a Neo-Latin compound word created by English speakers around 1880. It is for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 regions 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 sh ...

Blastocladiomycota
Blastocladiomycota is one of the currently recognized phyla within the kingdom Fungi.Hibbett DS et al. 2007. A higher-level phylogenetic classification of the fungi. Mycological Research 111:509–47. Blastocladiomycota was originally the order Blastocladiales within the phylum Chytridiomycota until molecular and zoospore ultrastructural characters were used to demonstrate it was not monophyletic with Chytridiomycota. The order was first erected by Petersen for a single genus, ''Blastocladia'', which was originally considered a member of the oomycetes.Sparrow FK. 1960. Aquatic phycomycetes. 2nd ed. Ann Arbor, Michigan: University of Michigan Press. Accordingly, members of Blastocladiomycota are often referred to colloquially as "chytrids." However, some feel "chytrid" should refer only to members of Chytridiomycota.Alexopoulos CJ, Mims CW, Blackwell M. 1996. Introductory Mycology. 4th edition. John Wiley & Sons, Inc.

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 a 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 German mycologist and medical doctor. 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 to the militar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
