The majority of Hemitrichia species can be found on rotten or dead logs[5] in lowland forest. requirement of the selected species i.e., Hemitrichia serpula. RESUMO – (Hemitrichia serpula var. 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. For Students, Faculty, and Staff. Rostaf., Versuch eines Systems der Mycetozoen: 14 ( ) [MB#]. Hemitrichia serpula Myxomycetes. [6] DNA analysis of H. serpula was able to show that Myxomycetes, like most species, are subject to environmental barriers in gene flow, allowing for the development of new species or clades.[6]. Hemitrichia serpula (Scop.) Hemitrichia serpula was the most dominant species in Pinus koraiensis forest. [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. Author: Mgr. Key words: Myxomycetes, Physarales, new record, taxonomy. The other kind is the sporangium, which is a round case that holds a mass of spores. Hemitrichia serpula (Scop.) [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. The structural parts of a sporangium, going from exterior to interior, are the peridium, hypothallus, stalk, … 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. The spores will develop within a walled structure, and when they are mature they will be released to disperse through multiple means. The amoeba form is preferred for terrestrial environments, while the swimming ability of flagella is preferred in a wet environment. Pers. Plasmodium will then begin to form fruiting bodies, which will hold the haploid spores. CABI Bioscience, CBS and Landcare Research, available online at www.indexfungorum.org. May 27, 2012 - Explore Gianluca Finazzi's board "Mostre e Musei", followed by 210 people on Pinterest. — Nach Lister. The other kind is the sporangium, which is a round case that holds a mass of 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. [4] This plasmodium stage usually exists from late spring until early fall.[5]. Fengyun Zhao, Yu Li, Tom Hsiang, Shuyan Liu. Hemi comes directly from the Greek prefix hemi, meaning “half”. [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). Dec 11, 2020 - Explore Erik van der Zee's board "model" on Pinterest. Lister. They are sent to a computer by website operators or third parties. Species of Hemitrichia have been found on four major landmasses: Asia, Europe, North America and South America. The plasmodium feeds on bacteria, other microorganisms and can even cannibalize other slime molds. Hemitrichia serpula (Scop.) Trenčín. These are immobile, tube-like veins of fruiting bodies that form a net. 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. Hemitrichia serpula. Hemitrichia serpula forms such a fruiting body. Author: John Carl Jacobs (JCJacobs) Licensing. Hemitrichia serpula (Scop.) [Descriptions of Fungi and Bacteria]. Two species of Hemitrichia offer important insights into the evolution of the myxomycetes. 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. A description is provided for Hemitrichia serpula, a myxomycete which occurs on dead fallen leaves, petioles, spathes, bark, branches, logs, stumps, trunks, twigs, and decaying wood (including artefacts) of a wide range of plants. Synonyms: Mucor serpula Scop. [5] An example of this is Hemitrichia clavata, which forms small sporangia held on a stalk that open to reveal brightly red to yellow coloured mature spores. [6] Of the 26 recognized species, 13 have been found in the Neotropical Region. Hemitrichia serpula (Scop.) Figure.2 Photomicrographs of H. serpula A- Capillitium and Spores. This study suggests that vegetation type has an important influence on the species composition and diversity of myxomycetes. George Barron: Recent submissions. Previous Page. Taxon category: Accepted. A normal copyright tag is still required. Mycology Proceedings C 86(2): 143-153. 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. [7], Hemitrichia is one of six current genera within the family Trichiaceae within the order Trichiida. References. H. serpula can be found in lowland forests of most of the major continents, including Asia, Europe, North America and South America, demonstrating their ability to disperse spores upwards of thousands of miles. This tag does not indicate the copyright status of the attached work. [9] This demonstrated the hardiness of the spores, as well as providing an explanation for their ability to survive widespread dispersal. The pretzel-like branches of the plasmodium twist and turn, forming a. Rostaf. Plasmodiokarpien kriechend, + wurm- förmig, meist netzartig verbunden und oft mehrere Quadrat- zentimeter bedeckend, goldgelb bis bräunlichgelb. (2010) Index Fungorum. Hemitrichia serpula. Cite this article. piauiensis Cavalcanti & Mobin é descrita e ilustrada. Kirk, P. 1772 Trichia serpula (Scop.) Hemitrichia species exhibit either plasmodiocarp or sporangium fruiting bodies, both of which are well-known and recognizable slime molds seen on multiple continents. Hemitricha is a genus of slime molds, of the family Trichiidae, found within the order Trichiida. Notes: Slime molds do not form penetrating or absorptive masses of hyphae on the wood substrate. Eliasson, U. Nannenga-Bremekamp, N.E. Rather, slime molds form structures called plasmodia, which do not have cell walls. 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. Hemitrichia serpula (Scop.) These slime molds are It is a saphoritic fungus: [11] These spores will then disperse and change into the haploid ameoboflagellate stage, starting the process over again. Mucor serpula Scop. [2] The genus has also previously been referred to as “Hemiarcyria” by Fries in 1829 and as “Hyporhamma” by Corda in 1854. May 29, 2017 - Image result for vintage classification charts The majority of the field has relied on morphological features, which often only emphasize the plasmodium life cycle of the organism. [6] The species' distinct morphology and its extremely wide spread habitat allowed Hemitrichia serpula to be used to study the process of speciation and gene flow in the Myxomycetes. Species serpula. It was first described by Josef Rostafinkski in his 1873 book “Versuch eines systems der mycetozoan”. [4] The massive cytoplasm contains multiple nuclei, contractile vacuoles, mitochondria and food vacuoles found on the peripheral edge of the plasmodium. Trichiida are endosporous Myxomycetes, meaning their spores are held within an acellular structural wall. Plasmodiokarp (*"/,). Hemitrichia serpula. Hemitrichia serpula (Scop.)

The pretzel-like branches of the plasmodium twist and turn, forming a. The genus includes Hemtrichia serpula, known as the pretzel slime mold, an iconic and widespread species that has been used to examine speciation in slime molds.
