Spores of the species Hemitrichia clavata spores were found to be viable and able to germinate after 75 years in storage. Hemitrichia serpula is probably one of the most well-known and recognizable slime molds due to its distinct golden yellow net-shaped appearance, which acts as the main morphological feature used to identify the species. This tag does not indicate the copyright status of the attached work. Rostaf., Sluzowce Monografia: 266 (1875) [MB#182483] Tweet; Description: Orange, pretzel-shaped network of slime mold strands. References. [3] “The Myxomycetes” by G.W Martin and C. Alexpoulous, a monograph considered to be one of the most important and influential works on the plasmodial slime molds,[4] describes the genus as having a capillitium with tube-like threads that are connected into a net, with either free or connected free ends, and decorated with several spiral bands.[5]. Vědecká synonyma. search Search Type Web Directory your own Pins on Pinterest [11] These spores will then disperse and change into the haploid ameoboflagellate stage, starting the process over again. May 29, 2017 - Image result for vintage classification charts The presence of a net-like capillitium is likely the most defining and recognizable feature of the genus Hemitrichia, as it has been mentioned by almost every author in his or her description of the genus. They are sent to a computer by website operators or third parties. These slime molds are It is a saphoritic fungus: Plasmodiokarpien kriechend, + wurm- förmig, meist netzartig verbunden und oft mehrere Quadrat- zentimeter bedeckend, goldgelb bis bräunlichgelb. (ed.) [4], The amoeboflagellated stage will undergo sexual reproduction, as two cells fuse to create a diploid cell. Rostaf. [2] Hemitrichia is described as having capillitium threads that can either be free or fused into a net. Currently, Hemitrichia remains a well-studied slime mold genus, with over 40 described species found on multiple continents. This cell will then undergo many rounds of nuclear division without any cellular division, resulting in a rapidly growing, membrane-bound cell with multiple nuclei known as the plasmodium. [4] These cells are able to exist as either amoeba or flagellates depending on the conditions the cell experiences, and are hence known as amoeboflagellates. Fengyun Zhao, Yu Li, Tom Hsiang, Shuyan Liu. Derivation of name: Serpula means "a little snake." [5] These nets will take on the colour of the spores within them, which ranges from yellow to red as is expected in superorder Lucisporidia, or the brightly coloured slime molds. Habitat: Habitat: Under the bark of a snag in a deciduous forest. [4] Slime molds spend a period of their life cycle as a myxameoba or a swarm cells. It was first described by Josef Rostafinkski in his 1873 book “Versuch eines systems der mycetozoan”. Figure.1 Plasmodiocarpus fruiting body of Hemitrichia serpula on dried leaves of Cocus nucifera. Now showing items 41-60 of 2117. Eliasson, U. Nannenga-Bremekamp, N.E. Josef Rostafinkski described Hemitrichia in the family Trichiaceae, along with another genera Trichia. CABI Bioscience, CBS and Landcare Research, available online at www.indexfungorum.org. Hemitrichia serpula (Scop.) [6] Further molecular research into slime mold taxonomy could reveal more information on the family tree and evolution of Hemitrichia. Hemi comes directly from the Greek prefix hemi, meaning “half”. See more ideas about polar bear dogs, unlikely animal friends, pomsky dog. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium. František ŠARŽÍK [Determination history and verification] - Easily determinable species Origin of image. The National Biodiversity Data Centre mapping system (Biodiversity Maps) integrates the mapping of terrestrial as well as marine data and is intended to serve as a portal for the geographic presentation of observational data on Ireland's biological data. Plasmodiokarp (*"/,). For Students, Faculty, and Staff. [7] In the genus Hemitrichia, these tube-like capillitium threads will form an “elastic net”. The best example of this is Hemitrichia serpula, which forms distinctive gold-yellow networks of tubes that will burst to reveal spores when they are mature. Hemitrichia serpula (Scop.) Martin and Alexpoulous’ monograph also mentions that the genus includes some species that would also fit well under two other Trichia genera: the Arcyria and Trichia. Hemitrichia species exhibit either plasmodiocarp or sporangium fruiting bodies, both of which are well-known and recognizable slime molds seen on multiple continents. Hemitrichia therefore refers to the condition of partially having hair. The spores will develop within a walled structure, and when they are mature they will be released to disperse through multiple means. The structural parts of a sporangium, going from exterior to interior, are the peridium, hypothallus, stalk, … Hemitrichia serpula. The genus Hemitrichia currently has 28 accepted species:[12], "An online nomenclature information system of Eumycetozoa", https://en.wikipedia.org/w/index.php?title=Hemitrichia&oldid=995259377, Articles with unsourced statements from July 2018, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 December 2020, at 01:40. X�Ű< Z�7��r.z��Mj�S(ٔ)h� Trichia was described as having numerous capillitium threads, which are free and tapered at the ends. [Descriptions of Fungi and Bacteria]. The other kind is the sporangium, which is a round case that holds a mass of spores. Next Page. Hemitrichia serpula (Scop.) Figure.2 Photomicrographs of H. serpula A- Capillitium and Spores.

HEMITRICHIA Serpula My Birthday: October 25, 1993 Fungi's bithday is Oct. 2007 Food Source Digesting things such as bacteria, yeasts, microalgae, protozoa, particles of organic detritus, and sometimes others of their own species. Pers. Plasmodium will then begin to form fruiting bodies, which will hold the haploid spores. [2], As in all members of the Trichiida order, the structure of the capillitium plays a major role in identifying and defining the different families and genera. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium. The majority of Hemitrichia species can be found on rotten or dead logs[5] in lowland forest. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium.

Rostaf., Versuch eines Systems der Mycetozoen: 14 () [MB#]. Skip to main content. [4] This plasmodium stage usually exists from late spring until early fall.[5]. This study suggests that vegetation type has an important influence on the species composition and diversity of myxomycetes. Rostaf., Versuch eines Systems der Mycetozoen: 14 ( ) [MB#]. Very little molecular research has been done to fully explore the phylogeny and evolution of the slime molds. [Descriptions of Fungi and Bacteria]. Notes: Slime molds do not form penetrating or absorptive masses of hyphae on the wood substrate. Under adverse conditions, such as a poor environment, overcrowding or the presence of toxins, these cells can encyst into small, walled cysts that can return to the amoeboflagellate form if conditions improve. Rostaf. Taxon category: Accepted. Uma nova variedade de Hemitrichia serpula (Scop.) [8] Members of the family Trichiaceae are described as having sessile or stalked fruiting bodies, and either hold spores in a plasmodiocarpic or a sporocarpic vessel[9] (see Life cycle). piauiensis (Trichiaceae, Myxomycetes) - uma nova variedade do Brasil).
