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. This type of plasmodium has a lot of rapid cytoplasmic streaming, veins aka branchesand granular protoplasm. The amoeba form is preferred for terrestrial environments, while the swimming ability of flagella is preferred serpyla a wet environment.
Stephenson and Carlos Rojas. Trichiida are endosporous Myxomycetes, meaning serpulaa spores are held within an acellular structural wall4. The North American Slime Moulds 2nd ed. Hemitrichia species exhibit either plasmodiocarp or sporangium fruiting bodies, both hdmitrichia which are well-known and recognizable slime molds seen on multiple continents.

Whitish to yellowish plasmodium and mustard-yellow plasmodiocarp appears on dead wood, leaves, and plant litter; June through August.

Spores of the species Hemitrichia clavata spores were found to be viable and able to germinate after 75 years in storage. Versuch eines systes der mycetozoen. These amoeboflagellates also contain a single nucleus, which at this stage in the life cycle is haploid. Other fungal links Bibliography links General links Molecular links Specimens and strains links.
Trichia was described as having numerous capillitium threads, which are free and tapered at the ends. 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.
