Derivation of name: Serpula means "a little snake." May 29, 2017 - Image result for vintage classification charts [4] Slime molds spend a period of their life cycle as a myxameoba or a swarm cells. [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]. George Barron: Recent submissions. 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. Rostaf. [4] In MacBride's book, Hemitrichia represents an intermediate between Arcyria and Trichia, and he notes that the presence of the net formation in the capillitium was similar to Arcyria, while the spiral bands are a distinct feature in the Trichia genera. 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. Mucor serpula Scop. A normal copyright tag is still required. [4] They are members of the superorder Lucisporidia, which are the brightly coloured Myxomycetes that lack a feature called the columella, which is an extension of the spore stalk through the structure that holds the spores. [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]. Wind has often been cited as the main means of dispersal, but other modes such as sticking to insect legs have been proposed. This tag does not indicate the copyright status of the attached work. These amoeboflagellates also contain a single nucleus, which at this stage in the life cycle is haploid. Lister. [11] These spores will then disperse and change into the haploid ameoboflagellate stage, starting the process over again. Eliasson, U. Hemitrichia serpula (Scop.)

The majority of Hemitrichia species can be found on rotten or dead logs[5] in lowland forest. Hemitrichia serpula (Scop.) Plasmodium will then begin to form fruiting bodies, which will hold the haploid spores. [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. [citation needed]. The other kind is the sporangium, which is a round case that holds a mass of spores. Family members also have tube-like capillitium that are hollow and can have “decorations” such as spirals or spines. requirement of the selected species i.e., Hemitrichia serpula.

These are immobile, tube-like veins of fruiting bodies that form a net. Tweet; Description: Orange, pretzel-shaped network of slime mold strands. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium. [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. [2] Rostafinksi describes the genus as having “[c]apillitium tubes fused into nets, free or with single tapered ends trapped between stalk contents”. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium. They are sent to a computer by website operators or third parties. Hemitrichia therefore refers to the condition of partially having hair.

Hemitrichia serpula. An individual sporangium is usually of characteristic size, shape, and color and represents the most common and basic fruiting body type. 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). Trichiida are endosporous Myxomycetes, meaning their spores are held within an acellular structural wall. Trichia was described as having numerous capillitium threads, which are free and tapered at the ends. Rostaf., Sluzowce Monografia: 266 (1875) [MB#182483] Hemitrichia serpula (Scop.) Key words: Myxomycetes, Physarales, new record, taxonomy. Home. Hemitrichia. [Descriptions of Fungi and Bacteria].

Dec 22, 2014 - This Pin was discovered by Elise Cope. These macroscopic forms of the slime mold are the most well-known and best-studied stage of the life cycle. Rostaf. Very little molecular research has been done to fully explore the phylogeny and evolution of the slime molds. Massee Common name(s): Pretzel slime. 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.

Hemitricha is a genus of slime molds, of the family Trichiidae, found within the order Trichiida. [9] This demonstrated the hardiness of the spores, as well as providing an explanation for their ability to survive widespread dispersal. The majority of the field has relied on morphological features, which often only emphasize the plasmodium life cycle of the organism. ;Arcyria serpula (Scop.) Fengyun Zhao, Yu Li, Tom Hsiang, Shuyan Liu. The plasmodium feeds on bacteria, other microorganisms and can even cannibalize other slime molds. [4] This plasmodium stage usually exists from late spring until early fall.[5]. The amoeba form is preferred for terrestrial environments, while the swimming ability of flagella is preferred in a wet environment. It was first described by Josef Rostafinksi in 1873 and remains a well-defined genus of the slime molds. Habitat: Habitat: Under the bark of a snag in a deciduous forest. The pretzel-like branches of the plasmodium twist and turn, forming a. Species serpula. Lycogala epidendrum - mature aethalia, brown  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. In this book, the genus Hemitrichia is described as having the “[c]apillitium a tangled net of more or less branching and [cross-connecting] fibres” as well as detail about the capillitium threads, which are “conspicuous spirally winding bands or ridges”. Apr 24, 2019 - Cartographer and artist Stephen Walter’s latest map traces the lesser known streams, sewers, springs and culverts of the capital in intense, hand-drawn detail 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. Hemitrichia serpula: Scientific name: Hemitrichia serpula (Scop.)Rostaf. [10] Hemitrichia species can have two kinds of fruiting bodies. Pers. The spores will develop within a walled structure, and when they are mature they will be released to disperse through multiple means. Rostaf., Versuch eines Systems der Mycetozoen: 14 ( ) [MB#]. [9] One kind is known as a plasmodiocarp. [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. [3], In 1922, Thomas MacBride published his second edition of The North American Slime Moulds, the monograph in which he first describes the Trichida order. 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. Cite this article. Josef Rostafinkski described Hemitrichia in the family Trichiaceae, along with another genera Trichia. 1797 Hemiarcyria serpula (Scop.) 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. Hemi comes directly from the Greek prefix hemi, meaning “half”. [4], The amoeboflagellated stage will undergo sexual reproduction, as two cells fuse to create a diploid cell. Rost. [7] In the genus Hemitrichia, these tube-like capillitium threads will form an “elastic net”. [6] Of the 26 recognized species, 13 have been found in the Neotropical Region.

Taxon category: Accepted. [2] Hemitrichia is described as having capillitium threads that can either be free or fused into a net. (ed.) 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. 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. Figure.1 Plasmodiocarpus fruiting body of Hemitrichia serpula on dried leaves of Cocus nucifera. [5], Members of the Hemitrichia follow the typical plasmodial slime mold life cycle, which exhibits two main stages as well as possible sexual reproduction. [1] Trichia is combination of the Greek trichios, which refers to hair or hair-like structure and –ia, referring to a condition,[1] leading to –trichia being the condition of having hair. Trenčín. Hemitrichia serpula. Eliasson, U. Nannenga-Bremekamp, N.E. 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. Hemitrichia serpula on the surface of a rotting log. Rostaf., Versuch eines Systems der Mycetozoen: 14 ( ) [MB#]. In this case, instead of forming separate sporangia, the whole plasmodium is transformed into a mass of spores in this beautiful, maze-like structure It was first described by Josef Rostafinkski in his 1873 book “Versuch eines systems der mycetozoan”. 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. 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. Plasmodiokarp (*"/,).
