Hello, my name is Hemitrichia serpula. I would like to tell you all about myself. I am an elongated, mummy-shaped diatom, which means I grow a silica shell around myself. This silica shell is an absolute requirement for me for metabolism.

I'm an acellular "true" slime mold and form conspicuous, yellow, reticulate plasmodiocarps on humus. I prefer marine environments and am currently in an endosymbiotic relationship with a duckweed plant in a pond, which is going pretty good for me.

My plasmodiocarps are derived from phaneroplasmodium veins and can be up to several centimeters across. My major vegetative state is multinucleate and I have migratory plasmodium, which have rapid flow. To tell you a little about my plasmodium-it's thick, has granular protoplasm, and sporangia form on it. I like to feed often by moving my plasmodium over and digesting things such as bacteria, yeasts, microalgae, protozoa, particles of organic detritus, and sometimes others of my own species, lots of nutrition.

I am also multi-spored and very brightly colored. I can also form macroscopic fruiting bodies, which develop from my plasmodium. As for reproduction, it is oogamous sexual reproduction with alternate haploid and diploid phases.

The male gametes have a single flagellum. When I find a cell that is compatible with me, I fuse with it and a zygote develops in the vegetative stage called phaneroplasmodium. Well, enough about myself. I hope you thought I was a very interesting microorganism. References: 1. Laskin and H. Sainsbury, Diana and Singleton, Paul.

Hemitrichia serpula

Hemitricha is a genus of slime molds, of the family Trichiidae, found within the order Trichiida. It was first described by Josef Rostafinksi in and remains a well-defined genus of the slime molds. Hemitrichia species exhibit either plasmodiocarp or sporangium fruiting bodies, both of which are well-known and recognizable slime molds seen on multiple continents. 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. Hemitrichia therefore refers to the condition of partially having hair. Josef Rostafinkski described Hemitrichia in the family Trichiaceae, along with another genera Trichia. Trichia was described as having numerous capillitium threads, which are free and tapered at the ends.
