Its propagation mode is mainly that idioblast divides the filaments into several small segments, which are called algal segments. The algal segments are easy to separate from idioblast, and each algal segment grows into filaments through cell division. This reproduction mode of algae is also a nutritional reproduction mode. It can fix nitrogen and be eaten. Auricularia auricula is a combination of fungi and algae, which generally grows in dark and humid places. It is dark and dark, a bit like soft auricularia auricula. It is more common on wet soil surface and still water surface, and wetlands after rain in summer are the most common and distributed everywhere. A lyric poem named "Step on Vegetables" written by Wang Pan in Qing Dynasty is included, saying: Step on vegetables in the field, it rains, and sunny days shine on the countryside. When I arrived at the village, my grandmother called Aoweng and hurried with her children. After a while, I picked a cage full of green flowers. I went home to eat and forgot my ferocity. "This ballad describes the growth of ears, hunger and famine relief. It can be seen that tremella has been an important natural wild vegetable in famine years since ancient times. I wonder how many working people have been saved. It is a gift from nature and has made an indelible contribution to the people.

Alias: Nostoc commune, Nostoc commune, Nostoc commune, Nostoc commune, lichen, Nostoc commune.

Scientific name: Nostoc commune: it is a combination of thallus, fungi and algae of Nostoc commune. Description: Also known as Nostoc commune. It is a common nitrogen-fixing cyanobacteria. Cyanophyta, Nostoc commune The colloid of algae was spherical at first, and then flattened and expanded into a flaky colloid with wavy surface, sometimes irregularly curled and often perforated. Blue-green, olive or brown. Microscopically, we can see that there are countless curved filaments embedded in the colloid, and there are no branches. Each filament has obvious colloid sheath, and some are not very obvious. The cells of algae filaments are short cylindrical or nearly spherical, and each algae filament is like a rosary. There are 1 to several idioblast in the algal filament cell line, which is nearly spherical, with uniform cytoplasm and yellowish or transparent color, and contains nitrogenase, so it is a place for nitrogen fixation.
