Origin and Common Names:
Thelopsis inordinata Nyl. is a species of lichen found in different parts of the world. It is commonly known as "Brown Fruited Curtain Lichen" or "Bare Bark Lichen" due to its preference for growing on bare tree trunks and branches. This lichen species belongs to the genus Thelopsis, which is a small group with only around ten known species worldwide.
General Appearance:
Thelopsis inordinata Nyl. typically grows in tufts or patches, forming curtains of brown fruiting bodies that are somewhat raised above the thallus surface. The thallus, which is the main body of the lichen, is olive-grey in color, with a slightly wrinkled surface and a lumpy texture. The fruiting bodies are formed on the margins of the thallus and have a brown disc-like appearance, measuring around 0.5 mm in diameter.
Uses:
Although not commonly used for medicinal purposes, Thelopsis inordinata Nyl. has been found to contain several secondary metabolites such as atranorin, gyrophoric acid, and physodic acid, which have shown potential anticancer, antimicrobial, and antiviral activities. Additionally, because of its ability to bioaccumulate trace elements, Thelopsis inordinata Nyl. can be used as a bioindicator of air pollution and heavy metal contamination in urban areas.
Light Requirements
Thelopsis inordinata Nyl. typically grows in a shaded environment, such as under the canopy of trees or on the bark of shaded rocks. It requires low to moderate light intensity and cannot withstand prolonged exposure to direct sunlight. In a laboratory setting, fluorescent or LED lights with a relatively low intensity can be used to simulate the plant's natural habitat.
Temperature Preferences
The ideal temperature for Thelopsis inordinata Nyl. is between 10-20°C. However, it can withstand temperatures as low as -10°C and as high as 30°C. The plant is adapted to temperate climates and cannot tolerate extreme heat or cold for extended periods. Therefore, it is crucial to maintain the temperature within the ideal range for optimal growth and development.
Soil Requirements
Thelopsis inordinata Nyl. can grow on a variety of substrates, including rock, wood, and soil. It prefers acidic to slightly alkaline environments, with a pH range of 5.0-8.0. The plant does not require nutrient-rich soil, and it often grows on depleted substrates. The substrate should be well-drained to prevent waterlogging and maintain an adequate moisture level. The substrate's moisture content can be maintained by periodic misting or by adding sphagnum moss to the substrate.
Cultivation of Thelopsis inordinata Nyl.
Thelopsis inordinata Nyl. is a lichen species that grows on rocks and bark of old trees. To cultivate it, you'll need to replicate its natural habitat by creating a rock garden or by mounting it on a piece of bark. If you live in an area with temperature and humidity conditions that are favorable to lichen, you might find it growing in the wild, and you can transplant it, but be sure to abide by environmental regulations before collecting any wild plant.
Watering Needs of Thelopsis inordinata Nyl.
Thelopsis inordinata Nyl. is a lichen species that is highly adapted to survive in harsh environments, including low moisture areas. When cultivating it, you should avoid saturating its habitat with water; in fact, it is best to allow it to dry out completely between watering, and make sure it does not stay moist for prolonged periods, as that may lead to rotting.
Fertilization for Thelopsis inordinata Nyl.
Thelopsis inordinata Nyl. is a lichen species that derives all of its nutrients from its environment and does not require added fertilizers to thrive. Any supplement you provide could lead to over-fertilization, and cause damage by interfering with the plant's natural balance.
Pruning for Thelopsis inordinata Nyl.
Pruning is not necessary for Thelopsis inordinata Nyl. as this species grows at a slow pace and does not interfere with surrounding plants. Instead of pruning, you may want to remove any debris or branches that may fall on the plant to avoid any damage. Similarly, avoid direct contact with the lichen when handling it, as any physical contact might damage its sensitive thallus.
Propagation of Thelopsis inordinata Nyl.
Thelopsis inordinata Nyl. is a rare species of lichen that is often found under the shade of trees in temperate to humid climates. It can be propagated using two methods: vegetative propagation and spore propagation.
Vegetative Propagation
Vegetative propagation involves taking a part of the plant and using it to produce a new one. The simplest method is to use a sharp pair of scissors or a scalpel to cut a small section of the lichen, making sure to include both the fungal and algal components. Place the cut section on a suitable substrate such as a piece of bark, a rock, or a soil surface that will provide the necessary nutrients and moisture. The cut section will gradually grow into a new plant.
Spore Propagation
Propagation by spores is a more complicated process but is necessary for genetic diversity. Thelopsis inordinata Nyl. produces spores in the apothecia, which are small, cup-shaped structures on top of its body. To propagate using spores, collect a mature apothecia and crush it in a Petri dish. Add a few drops of water to the dish to aid release of spores. Cover the dish to prevent contamination from other fungi and let it sit for a few days until spores start to germinate. Once spores have germinated, transfer them to a suitable substrate and wait for them to grow into new plants.
Disease and Pest Management for Thelopsis inordinata Nyl.
Thelopsis inordinata Nyl. is a resilient plant with no significant susceptibility to severe pests or diseases; however, taking precautionary measures are still important to avoid future problems. Here are some common diseases and pests that might affect Thelopsis inordinata Nyl. and ways to manage them:
Diseases
Fungal infections: Thelopsis inordinata Nyl. is known to be susceptible to different fungal infections, especially if the plant is placed in a shady environment. To manage this, it is essential to avoid overwatering, manage humidity, and regularly prune any damaged or infected plant parts, which further promotes air circulation. Moreover, use some fungicides with active ingredients such as copper or sulphur to control the fungal infection.
Pests
Spider mites: Spider mites are common pests that can damage Thelopsis inordinata Nyl. by sucking the sap from the leaves, creating yellowish or brown spots. To manage this pest, you can increase the humidity around the plant, which makes the environment unfavourable for the spider mites; alternatively, use insecticidal soap or neem oil to manage their growth.
Mealybugs: Mealybugs can also affect Thelopsis inordinata Nyl. by sucking the sap from the plant, causing it to wilt; they also excrete a sticky substance, which further attracts ants and promotes fungal growth. To manage this pest, use a cotton swab to dab some alcohol on the bugs or use neem oil or insecticidal soap regularly.
Therefore, regular screening and maintenance can help detect any unwanted pest or disease in a plant early enough.
