Retrieved from ” https: This Add-on is available at http: 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. These amoeboflagellates also contain a single nucleus, which at this stage in the life cycle is haploid. 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. Two species of Hemitrichia offer important insights into the evolution of the myxomycetes. Trenčín. [4] The massive cytoplasm contains multiple nuclei, contractile vacuoles, mitochondria and food vacuoles found on the peripheral edge of the plasmodium. The structural parts of a sporangium, going from exterior to interior, are the peridium, hypothallus, stalk, … Rost. Hemitrichia therefore refers to the condition of partially having hair. 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.

[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. [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. In this case, instead of forming separate sporangia, the whole plasmodium is transformed into a mass of spores in this beautiful, maze-like structure Notes: Hemitrichia serpula Common name: Pretzel Slime: Date: 20 September 2009: Source: This image is Image Number 57955 at Mushroom Observer, a source for mycological images.

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. A normal copyright tag is still required. — Nach Lister. [4], The amoeboflagellated stage will undergo sexual reproduction, as two cells fuse to create a diploid cell. It was first described by Josef Rostafinkski in his 1873 book “Versuch eines systems der mycetozoan”. An individual sporangium is usually of characteristic size, shape, and color and represents the most common and basic fruiting body type. Hemitrichia serpula (Scop.) 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. Wind has often been cited as the main means of dispersal, but other modes such as sticking to insect legs have been proposed. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium. Hemi comes directly from the Greek prefix hemi, meaning “half”. Lister.

[5], Members of the Hemitrichia follow the typical plasmodial slime mold life cycle, which exhibits two main stages as well as possible sexual reproduction. [11] These spores will then disperse and change into the haploid ameoboflagellate stage, starting the process over again. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium. Fengyun Zhao, Yu Li, Tom Hsiang, Shuyan Liu. Plasmodiokarp (*"/,). [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. [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]. These macroscopic forms of the slime mold are the most well-known and best-studied stage of the life cycle. Hemitrichia Serpula (Scop.) Mycology Proceedings C 86(2): 143-153. [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. 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.

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”. [4] Fusion with more diploid stage cells, and even with other plasmodium of the same species,[4] will continue to increase the size of the plasmodium. Eliasson, U. Trichia was described as having numerous capillitium threads, which are free and tapered at the ends. Rostaf., Sluzowce Monografia: 266 (1875) [MB#182483] [6] Of the 26 recognized species, 13 have been found in the Neotropical Region.

Plasmodium gelb. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium. Tweet; Description: Orange, pretzel-shaped network of slime mold strands. [7] In the genus Hemitrichia, these tube-like capillitium threads will form an “elastic net”. [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. [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.
