Physoderma
''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'').

Blastocladiomycetes
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.

Physodermataceae
Physodermatacae is a family of chytrid fungi in the order Physodermatales. Species in the family have a parasitic relationship with the host's physoderma. This family is distinctive in that it contains a thick wall around the sporangia to resist against unfavorable conditions. Sporangia releases from a host plant when rotting, dispersal is carried through the air. This family is not to be confused or related to basidiomycetes rusts and smut fungi. This parasite is distributed all across the world in aquatic, semi aquatic wetlands and in some ferns. Physodermatacae breaks into two distinguished clades: Physoderma and Urophlyctis ''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'', cau ..., which are grouped together because of the similar algal parasite called Paraphysoderma.

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] |
Angiosperms
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils are in the ...

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 ...
