Overview of Parmelia goebelii Zenker
Parmelia goebelii Zenker is a lichen species that belongs to the family Parmeliaceae. Commonly known as Goebel's trumpet lichen, this plant species is native to New Zealand and is commonly found growing on tree trunks and branches in forests and coastal areas.
Description of Parmelia goebelii Zenker
The plant's thallus is foliose and is small, growing up to 5 cm in diameter. The upper surface of the thallus is pale green to yellow-green, while the lower surface is black or dark brown with rhizines. It has short lobes with rounded tips that are marginal with sorediate. The soredia are small, arcticulate, and convex. The upper side of the lobes is smooth and glossy, while the lower side has dense sorediate bumps.
Uses of Parmelia goebelii Zenker
The plant is not widely used for commercial purposes. However, some indigenous communities in New Zealand traditionally use this plant for various purposes. The M?ori community used this lichen species to treat a wide range of diseases, including gastrointestinal issues, respiratory tract infections, and wounds. The lichen was boiled and consumed as a tea or chewed to extract its medicinal properties.
Apart from its medicinal properties, Parmelia goebelii Zenker is also used as a biomonitor for air pollution. Due to its sensitivity to air pollution, it can be used to indicate the levels of air pollution in different environments. Researchers have also shown that Parmelia goebelii Zenker could be used for cosmetic purposes, such as in the production of natural dyes for textiles, but more research needs to be conducted to determine its viability.
General Appearance of Parmelia goebelii Zenker
Parmelia goebelii Zenker has a unique appearance that is characterized by its small size and rounded thallus with lobes that have rounded tips. The upper surface of the thallus is smooth with a pale green to yellow-green hue, while the lower surface is black or dark brown with rhizines. The plant is relatively easy to identify in the field due to its sorediate bumps that appear on the lower surface of the lobes.
Overall, Parmelia goebelii Zenker is an interesting plant species that has attracted the attention of scientists due to its unique appearance and various medicinal and non-medicinal uses. It is an important plant species that plays an essential role in the ecosystem, and its preservation is critical for the continued well-being of the environment and the communities that rely on it.
Light Requirements
Parmelia goebelii Zenker grows well in moderate to low light conditions. It prefers partial shade or filtered sunlight, but direct sunlight should be avoided as it may cause the plant to dry out and become scorched.
Temperature Requirements
The ideal temperature range for Parmelia goebelii Zenker is between 16°C to 24°C. It can tolerate temperatures as low as 10°C and as high as 30°C. However, exposure to extreme temperatures should be avoided as it may hamper the growth of the plant.
Soil Requirements
Parmelia goebelii Zenker prefers well-draining soils that are rich in organic matter. It can grow in a wide range of soil types, including loamy, sandy, or rocky soils. However, the soil should be slightly acidic with a pH ranging from 5.5 to 6.5. The plant can also grow on other surfaces, including rocks or tree bark.
Cultivation Methods
Parmelia goebelii Zenker is a type of lichen that grows on tree bark in forests. It can also be cultivated in the garden on rocks, logs, or tree stumps. To cultivate, simply collect a small piece of lichen from a forest and attach it to the chosen surface using glue, string, or wire. The ideal time to transplant the lichen is in the early spring or fall.
Watering Needs
Parmelia goebelii Zenker requires little watering, as it is adapted to survive in the natural environment. However, during periods of drought, it can be misted with water. It is essential to avoid over-watering, as it can cause the lichen to become waterlogged and eventually die.
Fertilization
Fertilization is not required for Parmelia goebelii Zenker, as it obtains all its necessary nutrients from the surrounding air and environment. However, if the lichen is showing signs of nutrient deficiency, it can be fertilized with a nitrogen-rich fertilizer or by spraying it with a solution of diluted fish emulsion.
Pruning
Pruning is not required for Parmelia goebelii Zenker, as it does not have leaves or stems. However, it is essential to keep an eye out for any dead or brown parts and remove them using scissors or a knife. The dead parts can be taken out from the surface to which it is attached or left in its place, depending on personal preference.

Propagation of Parmelia goebelii Zenker can be done through two methods - vegetative propagation and sexual propagation.
Vegetative Propagation
In vegetative propagation, the lichen is multiplied through fragmentation or division of the thallus. In this method, small fragments of the thallus are taken and transplanted onto a suitable substrate to grow into a new thallus.
The best time to carry out vegetative propagation for Parmelia goebelii Zenker is during the rainy season. During this time, the lichen is moist and pliable, making it easier to handle and plant.
Sexual Propagation
Sexual propagation is done through the formation of spores. In this method, the thallus produces reproductive structures called apothecia that contain asci, which release spores. These spores then germinate on a substrate to form a new thallus.
The best time to collect spores is during the winter months when the lichen dries up and the apothecia release the spores. The spores are then scattered by the wind and settle on a suitable substrate.
Propagation of Parmelia goebelii Zenker is important for the conservation of this lichen species. Proper care should be taken when transplanting and collecting spores to ensure the survival of this lichen species.
Disease and Pest Management for Parmelia goebelii Zenker
Parmelia goebelii Zenker is a type of lichen that usually grows on rocks, bark, and soil. While it is relatively resilient to pests and diseases, there are still some issues that can arise. Here are some common diseases and pests that might affect the plant and suggestions for managing them:
Common Diseases
One of the most common diseases that can affect Parmelia goebelii Zenker is the so-called "lichen decline." This condition is characterized by a general degradation of the lichen's thallus, followed by a decline in its reproductive ability. Lichen decline can be caused by a variety of factors, including air pollution, habitat loss, and climate change. Unfortunately, there is not much that can be done to treat lichen decline. However, efforts to reduce the factors that cause it, such as reducing air pollution and preserving habitats, can help to slow its progression.
Common Pests
While Parmelia goebelii Zenker is less susceptible to pests than many other plants, it can still be affected by insect infestations. One common pest is the scale insect, which attaches itself to the lichen's thallus and feeds on its nutrients. If left untreated, a scale infestation can cause the lichen to die. To manage a scale infestation, the affected lichen can be gently brushed with a soft-bristled brush to remove as many of the insects as possible. A mixture of water and mild dish soap can also be used to kill the remaining insects. Additionally, introducing natural predators like ladybugs or lacewings can help to control the scale population.
Another pest that can affect Parmelia goebelii Zenker is the spider mite. These tiny pests can appear as white or red dots on the lichen's thallus, and can cause discoloration and distortion of the plant. To manage spider mites, the lichen can be washed with a spray of water to remove the mites. Additionally, introducing natural predators, like predatory mites or ladybugs, can help to control the spider mite population.
