Magn. is also used as a natural dye by some communities.
Growth Conditions for Lecidea oblongula H. Magn.
Lecidea oblongula H. Magn. is a lichenized fungus that is widely distributed across different regions of the world. It can be found growing on different substrates, including rocks, bark, and soil. The species has specific growth requirements that dictate its growth and survival in various habitats.
Light
Like most lichens, L. oblongula requires adequate light for photosynthesis. It grows well in areas where it can receive a maximum of 50% sunlight. Therefore, it is common to find this species growing on surfaces or habitats that offer enough light, like rocks and tree bark. In situations where the lichen receives inadequate light, it may become dormant or die due to limited energy supply.
Temperature
The growth and survival of L. oblongula are influenced by temperature fluctuations. The species thrives in a range of temperature conditions, with optimal growth occurring between 5-25?. At temperatures below 5?, the lichen becomes dormant, and its metabolic activities are significantly reduced. Conversely, temperatures above 25? may cause the lichen to become dehydrated, leading to death.
Soil Requirements
Besides light and temperature, L. oblongula has specific soil requirements for growth. The species is commonly found growing on different types of soils, such as sandy loam, silty clay, or loamy sand. A suitable substrate for L. oblongula should have good drainage and moderate nutrient content because an oversupply of nutrients may lead to the invasion of other algae species. Additionally, moisture content is vital, and soils with higher moisture content support the growth and survival of L. oblongula.
Cultivation Methods
Lecidea oblongula H. Magn. is a lichen plant that grows on rocks and bark in a wide range of climatic conditions. Cultivating this plant is challenging, and it requires specific methods for its growth. The best option for cultivation is to replicate its natural growing environment. Propagating through spores and fragments is the most common method to cultivate Lecidea oblongula H. Magn.
Watering Needs
The watering needs of Lecidea oblongula H. Magn. are minimal, and it can survive drought, but it needs to retain some moisture. The plant is adapted to grow in areas with scarce moisture, and it can extract water from the air. As a result, it is recommended to spray the plant whenever it starts to dry out to maintain its moisture content. Over-watering should be avoided as it may lead to rotting of the plant.
Fertilization
Lecidea oblongula H. Magn. is not a plant that needs fertilizers as it obtains nutrients from the surrounding environment. The plant is adapted to obtain its nutrients from the air and substrate on which it grows. Application of fertilizers may lead to the accumulation of chemicals in the plant and damage it. Therefore, there is no need for fertilizing Lecidea oblongula H. Magn.
Pruning
Pruning is not applicable to Lecidea oblongula H. Magn. as it does not possess leaves, stems, or roots. It grows flat on the surface of rocks or barks without any projections above the surface. However, removing any debris or unwanted material around the plant may help it grow healthily and avoid any competition for nutrients.
Propagation of Lecidea oblongula H. Magn.
Lecidea oblongula H. Magn. is a lichenized fungus species that grows on rocks and soil in tundra and alpine habitats. Propagation of this plant primarily involves vegetative means.
Vegatative Propagation
L. oblongula can be propagated vegetatively through thallus fragmentation, a process where small portions of the thallus or vegetative part of the plant break away and grow into new individuals.
Thallus fragments can be collected from the parent plant and then placed onto a suitable substrate, such as a rock or a soil surface. The substrate should provide enough moisture and nutrients to support the growth of the new plant.
Once the thallus fragments are placed on the substrate, it may take several weeks or months for the new individual to grow. The parent plant can produce several thallus fragments, which means that it can propagate several individuals at once.
Overall, vegetative propagation through thallus fragmentation is a reliable method for propagating L. oblongula and is especially useful for wild populations that are hard to collect from.
Disease Management
Lecidea oblongula H. Magn. is generally a hardy plant, with no major reported disease. However, it can be vulnerable to fungal infections that cause spotting on leaves, and sometimes entire leaves may wilt and die.
To manage these fungal infections, it is recommended to promptly remove any infected leaves and destroy them entirely rather than composting them, as this will help prevent the spread of the fungus to other areas of the plant. In severe cases, it may be necessary to apply a fungicide treatment to control the spread of the infection.
Pest Management
Like most plants, Lecidea oblongula H. Magn. can be affected by a range of pests. Commonly, aphids, spider mites, scales, and mealybugs may attack this plant.
One way to manage the pest infestation on this plant is by introducing natural predators such as ladybugs, lacewings, and wasps, which feed on these pests and help to control their population. Another effective method for managing pest infestations on Lecidea oblongula H. Magn. is to wash the plant leaves with a strong jet of water and remove any visible pests manually.
In severe cases, it may be necessary to apply insecticidal soap or other organic insecticides to control the pest infestation. Care should be taken to follow the manufacturer's instructions carefully when applying these treatments, as overuse may lead to harming the plant.
