Introduction: Umbilicaria lyngei Schol.
Umbilicaria lyngei Schol. is a species of lichen that belongs to the family Umbilicariaceae. It is commonly known as "Rock tripe" or "Stone shield lichen". The species was officially described in 1988 by the German lichenologist Johannes H. C. Scholz.
Origin and Distribution:
Umbilicaria lyngei Schol. is commonly found in cold regions of the Northern Hemisphere including the Arctic, Subarctic, and alpine zones. It is distributed across Canada, Alaska, and several parts of Northern Europe such as Iceland and Norway. It thrives in areas with high humidity and is usually found growing on rocks, stones, and steep slopes.
Appearance:
Umbilicaria lyngei Schol. has a distinctive, fan-shaped thallus that can range in size from 1-20cm in diameter. The thallus consists of a leathery, dark-brown upper surface and a pale undersurface. The edges of the thallus are often curled upward, giving it a shield-like appearance. Its reproductive structures are distinguishable by the presence of small cups (apothecia) that contain black spores.
Uses:
Umbilicaria lyngei Schol. has been used as a food source by indigenous peoples. It can be boiled or fried and is said to have a nutty flavor. Additionally, its high nitrogen content makes it a valuable source of protein. The species has also been used in traditional medicine to treat sore throats, coughs, and digestive problems. It is said to have antibacterial properties that make it effective in treating infections.
Moreover, the presence of Umbilicaria lyngei Schol. is evidence of ecosystem health as it is highly sensitive to environmental changes. Thus, its presence helps in monitoring air quality and pollution levels.
Growth Conditions of Umbilicaria lyngei Schol.
Umbilicaria lyngei Schol., commonly known as Lynge's navel lichen, is a terrestrial lichen species that can be found in different habitats in arctic and alpine regions. Understanding the growth conditions of this species is essential for successful cultivation and conservation efforts.
Light Requirements
Umbilicaria lyngei Schol. is a light-loving species that requires a significant amount of sunlight to thrive. However, it can also tolerate low light intensities, especially in high altitude regions where the sunlight is often scarce. The species can grow well under direct or indirect light.
Temperature Requirements
The growth of Umbilicaria lyngei Schol. is affected by temperature and humidity levels. This species can grow in a broad range of temperatures, including sub-arctic, arctic, and alpine environments. The ideal temperature range for the species ranges from 5 to 20°C. High temperatures in the summer may lead to desiccation and death of the species.
Soil Requirements
Umbilicaria lyngei Schol. grows on a variety of substrates, including rocks, soil, and mosses. This species prefers substrates with low nutrient levels, which are common characteristics of arctic and alpine environments. The soil pH values preferred by the species range from acidic to slightly alkaline. The soil should also be well-drained to prevent waterlogging, which often leads to the death of the species.
Cultivation Methods for Umbilicaria Lyngei Schol.
Umbilicaria lyngei Schol., commonly known as the Lungwort Lichen, is a type of lichen that is found in arctic and alpine regions. The best way to cultivate this plant is by collecting thallus fragments and attaching them to suitable substrates. The substrates can range from rocks to tree bark, and the fragments should be attached using a suitable adhesive.
Watering Needs for Umbilicaria Lyngei Schol.
Umbilicaria lyngei Schol. requires adequate moisture to survive and thrive. However, it is vital to note that this plant cannot tolerate over-watering. The lichen should be watered occasionally, and the substrate should be allowed to dry out between watering sessions. In cases where the substrate is too dry, the plant can be sprayed with water using a mist sprayer.
Fertilization
Umbilicaria lyngei Schol. does not require fertilization, as it obtains all its nutrients from the air and surrounding environment. The plant is self-sufficient, and any attempt at fertilization can do more harm than good. Therefore, no fertilizers should be used when cultivating and caring for this plant.
Pruning for Umbilicaria Lyngei Schol.
Umbilicaria lyngei Schol. does not require pruning, as it is a slow-growing plant that spreads slowly over the substrate. However, some lichens have a natural tendency to detach from the substrates, and in such cases, they may need to be reattached using suitable adhesives. In addition, any excess growth should be removed, leaving only healthy thallus fragments.
Propagation of Umbilicaria lyngei Schol.
Umbilicaria lyngei Schol. is a lichenized fungus that belongs to the family Umbilicariaceae. It is commonly known as Lynge's rock tripe and can be found in Arctic and alpine regions.
The propagation of Umbilicaria lyngei Schol. mainly occurs through vegetative means. The lichen forms foliose thalli, which can break apart into smaller fragments that can then establish themselves in new locations.
In addition to fragmentation, Umbilicaria lyngei Schol. can also propagate through the dispersal of its spores. The thalli contain small soralia, which are specialized structures that produce and release spores into the surrounding environment.
Propagation through spores is less common than vegetative propagation. However, it allows the lichen to colonize new areas and maintain genetic diversity.
Disease Management
Umbilicaria lyngei Schol. is susceptible to a few common fungal diseases such as black spot, powdery mildew, and rust. These diseases can cause discoloration, deformation, and death of the plant. To manage fungal diseases, maintaining proper cultural practices is crucial. Ensure adequate spacing between plants to promote air circulation and reduce humidity levels. Regularly prune away infected foliage and dispose of them properly. Use fungicides as a last resort if the disease is severe.
Pest Management
The most common pests that infest Umbilicaria lyngei Schol. are aphids, mites, and scale insects. These pests suck the sap of the plant, leading to yellowing and stunted growth. Inspect the plants regularly for any signs of infestation. Use insecticidal soaps, neem oil, or horticultural oil to control these pests. Predatory insects such as ladybugs or lacewings can also be introduced to the area to control the pests.
