Ferns ( Pteridopsida )
Order Dryopteridales
Family Lomariopsidaceae
Genus Lomariopsis.
Lomariopsis lineata — “Round Pellia moss”, “Loma fern”.
Distributed in China, Malaysia, Australia. The photosynthesizing gametophyte form of a terrestrial fern. At first glance, it looks very much like the liverwort Monosolenium, but 
much more beautiful and interesting. It differs by a less elongated, rounded shape of the prothallia and the absence of a central vein (strand) on them. It is also much thinner and almost transparent green. Sometimes referred to as large-leaf pellia.
Externally, it looks very impressive if tied to a substrate, volcanic lava, stone, driftwood, or decorations; this way it will look neatest and the growth rate will be higher. It has rhizoids and therefore gradually attaches to the substrate. The plant does not float, so you can simply place it either on the substrate or tie it with nylon thread to a stone or driftwood.
Since the moss grows very slowly, it will take several weeks for the prothallia to grow through the mesh. When it spreads, very beautiful green mounds are formed. It attaches well to lava or driftwood. The transparent lobes always grow in a cap-like shape, evenly covering the stone or branch. Lomariopsis can grow in one place for a long time without replanting and, most importantly, without any rot or bottom decay, even though light does not reach the lower layer of the fern. The lower part of the layer practically does not deteriorate, even if a thick layer builds up.
If the bush becomes too large, simply divide it into several parts that can start growing in any other place. It grows well in an aquarium, but not very quickly. It is ideal as a grazing ground for shrimp and as a shelter for small fish.
A very attractive plant that is undemanding to keeping conditions. Very easy to grow, even in low light conditions. It grows best under lighting of 0.3-0.4 W/L. Under stronger lighting, the growth intensity decreases, it becomes smaller and dark green. The growth rate is average, but under good conditions, it can grow quite quickly. Not demanding on fertilizers. Prefers soft water with pH 6.0-8.0; in hard water, it grows slower. Keeping temperature 18-30°C.
The development of the fern is very interesting and diverse — from a single fern spore, under sufficient humidity, a green sprout appears. After a few weeks, a heart-shaped formation appears from it — the prothallium. This is not yet a new fern, but a new generation from which the fern grows. Due to continuous cell division, this fern constantly grows underwater.
