Origin
Lecanora polychroma, also known as Anzi's Lecanora, is a lichen species that belongs to the family Lecanoraceae. It is commonly found in Europe, particularly in the alpine regions of the Swiss, Austrian and Italian Alps.
Common Names
The plant is commonly known by its scientific name, Lecanora polychroma, or its English name, Anzi's Lecanora.
Uses
While there are no known significant uses for Lecanora polychroma in modern medicine, it has been historically used in traditional medicine as a remedy for skin ailments, such as skin irritation and wounds. The lichen extract's chemical constituents have shown antifungal, antibacterial, and anti-inflammatory properties, making it a potential ingredient in some cosmetic products.
General Appearance
Lecanora polychroma is crustose, meaning it forms a crust-like structure on its substrate, which is often mineral soil or rocks. The thallus (body of the lichen) is usually pale grey or beige, but can sometimes be orange or bright yellow. It has small, flat, and circular discs that range from orange-brown to bright yellow, measuring up to 1cm in diameter. The discs are filled with small pits, known as ostioles, through which the lichen releases its spores. Lecanora polychroma is known for its vibrant colors and can be easily spotted in the rocky terrain of alpine regions.
Light Requirements
Lecanora polychroma thrives in areas with moderate light intensity. It requires sunlight to perform photosynthesis and grow. However, too much direct sunlight can be harmful to the plant.
Temperature Requirements
The plant requires favorable temperatures to grow properly. Lecanora polychroma can survive in a wide range of temperatures, but optimal growth occurs at a temperature range of 15-25°C.
Soil Requirements
Lecanora polychroma does not require specific soil types for growth. However, it prefers nutrient-rich soils with good drainage. The soil should also be slightly acidic to neutral for optimal growth.
Environmental requirements
The plant is resistant to drought and can survive in areas with low humidity. It is typically found in rocky and dry environments, such as cliffs, sand dunes, and other exposed areas.
Water requirements
Lecanora polychroma is a drought-resistant plant and can survive extended periods without water. It requires occasional watering to maintain its growth, but too much watering can be harmful. The plant thrives in areas with well-draining soil that prevents water stagnation.
Cultivation Methods for Lecanora Polychroma (Anzi) Nyl.
Lecanora polychroma (Anzi) Nyl. is a lichen and grows naturally on rocks, bark, and soil. As such, it can be challenging to cultivate this plant indoors. However, it is still possible with a little bit of effort.
The first step in cultivating Lecanora polychroma (Anzi) Nyl. is to find a suitable growing medium. It can be grown on rocks or bark, but it must be free from pollutants and chemicals that could harm the plant. Once you have found a suitable growing medium, you can then transfer the plant to it. During the transfer process, ensure that the plant is not damaged.
After you have transferred the plant to the growing medium, ensure you place it in an airy and well-lit location. Ideally, the plant should receive at least six hours of sunlight during the day.
Watering Needs for Lecanora Polychroma (Anzi) Nyl.
Lecanora polychroma (Anzi) Nyl. is a type of lichen that is incredibly hardy and can survive even in extreme weather conditions. As such, it does not require much watering.
You can water the plant every two weeks or when the growing medium starts to feel dry. When watering, use a misting bottle to spray the water on the plant gently. Avoid over-watering as it can cause damage to the plant.
Fertilization for Lecanora Polychroma (Anzi) Nyl.
Lecanora polychroma (Anzi) Nyl. obtains its nutrients from the air and does not require any fertilization. Fertilizers can harm the plant and should be avoided.
Pruning for Lecanora Polychroma (Anzi) Nyl.
Lecanora polychroma (Anzi) Nyl. does not require pruning since it is a lichen that grows naturally. However, ensure that any dead or damaged parts of the plant are removed to encourage new growth. Since the plant grows slowly, it is best to take your time when pruning to avoid damaging the plant's integrity.
Propagation of Lecanora polychroma (Anzi) Nyl.
Lecanora polychroma (Anzi) Nyl. is a lichen that belongs to the Lecanoraceae family. It grows on rocks, old walls, and sometimes on soil. Propagation of Lecanora polychroma involves both asexual and sexual reproduction. Below are the propagation methods for this plant.
Asexual propagation
Lecanora polychroma reproduces asexually through fragmentation. It can break off into pieces due to environmental factors like harsh weather conditions and animal disturbance. These fragments can develop into new thalli (thallus singular).
The fragments usually contain both fungal and algal components. It can grow on new substrates and establish a new colony. This propagation method is relatively faster than sexual reproduction.
Sexual propagation
Lecanora polychroma reproduces sexually through the formation of apothecia. Apothecia are cup-like structures that contain asci, which are sac-like structures that produce spores. The spores develop into new thalli and grow into a new colony.
The asci in apothecia are usually contained within a layer of fungal tissue called the hymenium. The hymenium also contains sterile tissues that help in spore discharge.
After the spores are released, they land on suitable substrates and germinate into new thalli. The process of sexual reproduction may take longer compared to asexual reproduction.
Disease Management
Lecanora polychroma is susceptible to different diseases, some of which may cause severe damage to the plant. The most common diseases that affect this lichen include:
- Anthracnose: This is a fungal disease characterized by the appearance of small, dark spots on the surface of the lichen. To manage this disease, it is crucial to remove infected material and improve air circulation around the plant.
- Leaf spot: Leaf spot is caused by fungi that attack the leaves of the lichen. The symptoms include the appearance of small, circular spots on the surface of the lichen. To control this disease, it is essential to ensure that the plant is not overwatered, and the leaves are kept dry.
- Root rot: Root rot is a fungal disease that causes the roots of the lichen to decay. To manage this disease, it is crucial to avoid overwatering and ensure that the soil has adequate drainage. The use of fungicides may also be necessary in severe cases.
Pest Management
Lecanora polychroma is also susceptible to pest infestations. Some of the most common pests that affect this lichen include:
- Aphids: These insects suck sap from the plant's leaves and stems, causing stunted growth and yellowing of the leaves. To manage aphids, it is recommended to use natural predators such as ladybugs or to spray the plant with insecticidal soap.
- Spider mites: Spider mites are tiny pests that feed on the sap of the lichen, causing the leaves to turn yellow and fall off. To manage spider mites, it is essential to ensure that the plant is kept well-watered and that the leaves are kept moist. The use of insecticidal soap may also be effective.
- Scale insects: Scale insects are small, oval-shaped pests that attach themselves to the stems and leaves of the lichen. They suck sap from the plant, causing yellowing and stunted growth. To manage scale insects, it is essential to prune and remove affected parts of the plant and use insecticidal soap or neem oil.
