Rostaf., Versuch eines Systems der Mycetozoen: 14 ( ) [MB#]. In its vegetative state, H. serpula is a light-yellow or golden-yellow-colored plasmodium. The pretzel-like branches of the plasmodium twist and turn, forming a.

When mature and conditions are suitable warm and wet conditionsthe organism produces fruit bodies that give rise to spores, which can germinate into two different types of haploid cells: Pairwise sequence alignments Polyphasic identifications.

With plasmodiocarps, the plasmodium structure is concentrated in the main branches, and a two-layer peridium forms around the outside of the plasmodiocarp structure 0.

Lily Eurwilaichitr and Dr. A Dictionary of Entomology. Up close, the capillitium is spinulose and resembles hemp-rope.
It is replaced each time there is a query done. Trichiida are endosporous Myxomycetes, meaning their spores are held within an acellular structural wall4.
Currently, Hemitrichia remains a well-studied slime mold genus, with over 40 described species found on multiple continents. Views View Edit History. Bernard Jabas 1 and Dr.
They are members of the superorder Lucisporidia, which are the brightly coloured Myxomycetes that lack a feature called the columella, which hemihrichia an extension of the spore stalk through the structure that holds the spores.

Hemitrichia – Wikipedia
The disrupted wall of a strand of plasmodiocarp at the hemtirichia left reveals the cottony, mustard yellow spore mass within. It was first described by Josef Rostafinksi in and remains a well-defined genus of the slime molds. 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. Species of Hemitrichia have been found on four major landmasses: The capillitium is made of lime, or calcium carbonate, and serves as a time-release mechanisim for the spores by trapping the spores in the matrix, letting them go when the time is right.
The best example of this is Hemitrichia serpulawhich forms distinctive gold-yellow networks of tubes that will burst to reveal spores when they are mature.
