Common Names
This species of lichen is commonly referred to as the sand-dune cladonia.
Uses
Cladonia submitis A. Evans does not have any known medicinal use. However, it is used as a bioindicator of environmental pollution and changes in climate. The lichen is able to absorb and retain pollutants from the environment, making it a useful tool for researchers to monitor air quality.
General Appearance
Cladonia submitis A. Evans is a small lichen, typically growing to a height of 1 – 3 cm. Its thallus is divided into branches that are tapered, cylindrical, and don't have any prominent cups. It has a light greenish-yellowish coloration that is sometimes covered in sand.
Growth conditions for Cladonia submitis A. Evans
Cladonia submitis A. Evans, commonly known as the Fringed Tube Lichen, is a species of lichen that belongs to the Cladonia family. It is notable for its unique fringed structure, which gives it a distinct appearance from other Cladonia species. The Fringed Tube Lichen can be found in a variety of habitats ranging from forests to grasslands, but it has specific growth conditions that must be met to thrive.
Light Requirements
Cladonia submitis A. Evans requires moderate to high levels of light for optimal growth. This species is often found in open areas with access to direct sunlight, such as grasslands or rocky outcrops. In shaded areas, the Fringed Tube Lichen may grow more slowly and have a less robust structure.
Temperature Requirements
The Fringed Tube Lichen has a wide temperature range and can tolerate both hot and cold environments. However, it grows best in cooler temperatures ranging from 5°C to 20°C. In hotter temperatures, the lichen may dry out and become dormant until conditions become favorable again.
Soil Requirements
Cladonia submitis A. Evans typically grows on well-drained soils with low to moderate nutrient content. It prefers acidic soils with a pH of 5 to 6.5. The lichen can also grow on rocky outcrops and other substrates such as bark or moss. In areas with a high nutrient content, the Fringed Tube Lichen may be outcompeted by other plant species and struggle to thrive.
Cultivation methods for Cladonia submitis A. Evans
Cladonia submitis A. Evans is a type of lichen that grows in the northern parts of America, Europe, and Asia. This lichen requires moist and cool conditions to grow properly. It can thrive in both natural and artificial environments.
If you plan to cultivate Cladonia submitis A. Evans, you must provide it with a suitable growth substrate like rocks, trees, or soil. This lichen can grow on different types of substrates, but the type of substrate you choose may affect its growth rate and development.
Watering needs for Cladonia submitis A. Evans
Cladonia submitis A. Evans requires constant moisture to grow and remain healthy. This lichen can withstand occasional dry periods, but prolonged droughts can harm it and dry it out. You can provide water to Cladonia submitis A. Evans by spraying it with water or misting it. Avoid using tap water as it may contain chemicals that can harm the lichen.
Fertilization of Cladonia submitis A. Evans
Since Cladonia submitis A. Evans is a lichen, it does not require any fertilizers to grow. This lichen can extract the necessary nutrients from the air and its substrate. Fertilizers can be harmful to Cladonia submitis A. Evans and may affect its growth and development, so it is better to avoid fertilizing it.
Pruning Cladonia submitis A. Evans
Cladonia submitis A. Evans does not require any pruning or trimming. This lichen grows slowly and does not become excessively large. It does not produce any leaves, branches, or flowers that require trimming. If you notice any dead or discolored portions of the lichen, you can gently remove them using a soft brush or a pair of tweezers.
Propagation of Cladonia submitis A. Evans
Cladonia submitis A. Evans is a fruticose lichen, meaning it consists of a fungal partner and an algal partner living in symbiosis. Lichens reproduce through both vegetative and sexual means. In nature, they primarily propagate through fragmentation or vegetative reproduction.
Fragmentation: Cladonia submitis A. Evans can propagate through fragmentation, which occurs when the lichen thallus breaks apart due to environmental factors, such as wind, rain, or animal activity. The separated fragments can then grow into new individuals if they land in a suitable habitat.
Vegetative propagation: Cladonia submitis A. Evans can also propagate vegetatively through soredia, which are small asexual structures composed of algal cells wrapped in fungal hyphae. Soredia can be dispersed by wind or other environmental factors and can settle in a suitable habitat to form a new individual. Another way for vegetative propagation to occur is through isidia, which are small, upright branches that grow on the lichen thallus. These can fall off and grow into new individuals.
Sexual reproduction: In addition to vegetative reproduction, Cladonia submitis A. Evans can also produce sexual reproductive structures known as apothecia, which contain the ascospores, the sexual reproductive cells. These spores are dispersed by wind or other environmental factors and can settle in a suitable habitat to form a new individual.
Overall, Cladonia submitis A. Evans is capable of propagating through a variety of methods that allow it to successfully colonize new habitats and expand its range.
Disease Management
Cladonia submitis A. Evans is a hardy plant that is relatively resistant to diseases. However, certain fungal infections might affect the health and productivity of this plant.
One of the most common diseases that can affect Cladonia submitis A. Evans is the leaf spot disease caused by the fungal pathogen Cercospora cladoniicola. This disease manifests in the form of small, circular spots on the plant's leaves. If left unchecked, the spots might enlarge and merge, resulting in extensive damage to the plant.
To manage leaf spot disease, it is essential to adopt preventive measures, such as ensuring proper air circulation, pruning infected leaves, and avoiding excessive watering. Fungicides containing mancozeb, copper sulfate, or tebuconazole might also help control the disease.
Pest Management
Cladonia submitis A. Evans is not very susceptible to pest infestations. However, certain insects and mites might pose a threat to the plant's health.
One of the most common pests that might affect Cladonia submitis A. Evans is spider mites. These tiny arachnids feed on the plant's sap, causing the leaves to turn yellow and appear stippled. If left untreated, spider mites can weaken the plant and make it susceptible to other infections.
To manage spider mites, it is essential to regularly inspect the plant for signs of infestation, such as webbing and stippling on leaves. Pruning the affected leaves, washing the plant with water, and applying insecticidal soap or neem oil might help control the pest.
Overall, with proper care and maintenance, Cladonia submitis A. Evans can remain healthy and productive, even in the face of diseases and pests.
