Overview
Lempholemma myriococcum (Ach.) Th. Fr., also known as the Sky-blue Pixie-cup lichen, is a type of lichen which belongs to the family of fungi. It is a unique and fascinating species that has been found in many different locations all over the world.
Origin
The origin of Lempholemma myriococcum can be traced back to Europe and North America. It is most commonly found in humid forests, growing on tree trunks and branches. The species prefers a temperate climate and is sensitive to pollutants in the air, making it a great indicator of air quality in the environment.
Common Names
The common names of Lempholemma myriococcum include Sky-blue Pixie-cup lichen, many-spored pixie-cup, and blue-green fairy cups. These names are used to describe the plant's unique and striking appearance, which is characterized by its vibrant blue-green color and cup-shaped structures.
Uses
Lempholemma myriococcum has no known uses in commercial or medicinal fields as it is not considered edible or toxic. However, it plays an important role in the ecosystem as it serves as habitat and food for many organisms including beetles, spiders, and small mammals. It also contributes to the process of photosynthesis, which helps in the production of clean air.
General appearance
Lempholemma myriococcum is a small lichen that grows to about 6 mm wide and approximately 1 cm tall. It is usually pale grey-green in color, but can also sometimes be blueish-green. The thallus, or body of the lichen, is cup-shaped and consists of a single layer of cells. The cups are often found clustered together, creating a beautiful and unique appearance.
Light Condition
The plant Lempholemma myriococcum prefers to grow in a shaded or semi-shaded area. Too much direct sunlight will harm the plant, causing its leaves to wither or its growth rate to slow down. Maintaining a balance is crucial for keeping the plant healthy and productive. Therefore, placing the plant near a window that receives a few hours of morning or late afternoon sunlight is ideal.
Temperature
The plant grows well in temperature ranges from 15°C to 25°C. It is sensitive to cold temperatures and may wilt or die if exposed to frost. To prevent temperature fluctuations, the plant should be kept in a stable environment where the temperature is consistent. Also, the plant can thrive in a well-ventilated place where there is a steady breeze that helps maintain an adequate amount of humidity.
Soil Requirements
The plant Lempholemma myriococcum prefers soil that is well-drained, slightly acidic, and rich in nutrients. It can tolerate slightly sandy soil, but clayey soil may hinder its growth. Mixing compost or organic matter into the soil can improve its fertility. The pH level should be maintained between 5.5 and 6.5. Overwatering can damage the plant's roots, so it is essential to keep the soil moist but not drenched.
Cultivation of Lempholemma myriococcum
Lempholemma myriococcum is a hardy plant that can thrive in a wide range of conditions. It can be grown both indoors and outdoors, as long as it receives adequate light and water.
If you are growing Lempholemma myriococcum indoors, it is best to place it near a south-facing window that gets plenty of sunlight. If you are growing it outdoors, be sure to choose a spot that receives partial shade, especially during the hottest part of the day.
Lempholemma myriococcum grows well in most types of soil, but it prefers a slightly acidic soil with good drainage. To improve drainage, you can mix compost or perlite into the soil before planting.
Watering needs of Lempholemma myriococcum
Lempholemma myriococcum prefers to be kept moist but not soggy. Watering once or twice a week is usually sufficient, but you should adjust the watering schedule based on the conditions in your growing environment. If you are growing it in a very dry or hot environment, you may need to water it more frequently.
When watering Lempholemma myriococcum, be sure to water the soil rather than the leaves. Watering the leaves can cause disease and damage to the plant.
Fertilization of Lempholemma myriococcum
To keep your Lempholemma myriococcum healthy and thriving, it is important to fertilize it regularly. You can use a balanced, water-soluble fertilizer once a month during the growing season. Be sure to follow the instructions on the fertilizer package carefully, as over-fertilization can damage the plant.
If you prefer to use organic fertilizers, you can use compost or well-rotted manure. Apply a thin layer to the soil around the plant once or twice a season.
Pruning of Lempholemma myriococcum
Lempholemma myriococcum does not require much pruning, but occasional trimming can help to keep it healthy and looking its best. You can prune any dead or damaged leaves or stems as soon as you notice them. This can help to prevent disease from spreading and can also improve the appearance of the plant.
If you notice that your Lempholemma myriococcum is becoming too large or unruly, you can also prune it to shape. Be sure to use sharp, clean pruning shears and make clean cuts to avoid damaging the plant.
Propagation of Lempholemma myriococcum
There are several methods for propagating Lempholemma myriococcum, a lichenized fungi commonly known as "lichen." The most common technique for this species is vegetative propagation, but it can also be propagated using soredia or isidia.
Vegetative Propagation
Vegetative propagation involves breaking off a portion of the thallus and transplanting it to a new location. This method is best used during the lichen's growth period in the Spring. The transplant location needs to be conducive to the lichen's growth needs, which include adequate moisture and sunlight. The transplanted lichen will require a period of stabilisation in the new location.
Soredia Propagation
Soredia are small fragments of the thallus that detach and disperse via wind or water. These fragments contain both fungal and algal cells that allow for self-sufficient reproduction. Soredia can be collected and transplanted upon a suitable substrate. Once transplanted, the soredia will continue to grow and develop a new thallus, independent of the parent thallus.
Isidia Propagation
Isidia are small, finger-like growths that protrude from the thallus surface. The immature isidia contain both fungal and algal components needed for growth. These structures can break off and attach themselves onto a new substrate, where they continue to grow and develop into a new thallus. Isidia propagation is similar to soredia propagation and can be a highly effective method of reproduction for Lempholemma myriococcum.
Disease Management for Lempholemma myriococcum
Lempholemma myriococcum is generally a sturdy plant with no significant disease issues. However, if your plant is unhealthy, it may develop some common fungal diseases.
Anthracnose: This fungus causes black or brownish splotches on the leaves. It can be managed by removing infected leaves and stems and cleaning up any plant debris on the ground. Avoid overhead watering and improve air circulation by pruning the plant to increase sunlight penetration.
Leaf spot: It is caused by the fungus Cercospora. The symptoms include circular, brownish spots on the leaves. Remove affected leaves and apply a fungicide, following the instructions on the label.
Rust: Rust disease causes yellowish spots on the tops of leaves, while the undersides develop orange or brownish pustules. Remove and destroy affected leaves and stems, and prevent future outbreaks by using a fungicide that contains copper.
Pest Management for Lempholemma myriococcum
There are some pests that may pose a threat to the health of your Lempholemma myriococcum plant, including:
Spider mites: These tiny, eight-legged pests suck on plant sap, causing yellowing leaves and a decrease in plant vitality. Spider mites can be managed by washing the plant with a forceful stream of water. Use neem oil, insecticidal soap, or miticide to control severe infestations.
Aphids: Aphids are small, sap-sucking insects that can cause distorted leaves and stunted growth. Remove aphids by spraying the plant with water or by applying insecticidal soap. Use ladybugs or green lacewings to introduce natural predators.
Mealybugs: Mealybugs cause yellowing and wilting of leaves. They secrete a white, cottony substance that helps to protect them from predators. Remove them by scraping them off by hand, then wash the plant with insecticidal soap, or use neem oil or horticultural oil.
