Origin
Mycomicrothelia capitosa, also known as Krempelh's Mycomicrothelia, is a species of lichenized fungi in the family Mycomicrotheliaceae. It is widely distributed in tropical and subtropical regions worldwide, such as Africa, Asia, Australia, and America.
Common Names
The common names of Mycomicrothelia capitosa include Krempelh's Mycomicrothelia, Anthracothecium capitosa, and Red-fruit Jasonia.
Uses
There are no known specific uses for Mycomicrothelia capitosa. However, lichens in general have been used in traditional medicine, food, and dyes. Some lichens also have potential uses in pharmacology, environmental monitoring, and bioprospecting.
General Appearance
Mycomicrothelia capitosa is a lichenized fungi that forms small, cup-shaped fruiting bodies called apothecia. The apothecia are orange-red to dark red, and measure 0.2-1 mm in diameter. The thallus, which is the body of the lichen that encloses the fungal and algal partners, is inconspicuous and crustose, meaning it is firmly attached to the substrate. The thallus color is usually white, cream, or pale yellowish-brown.
Light Requirements
Mycomicrothelia capitosa requires a moderate amount of light to grow. Direct sunlight should be avoided as it can cause damage to the plant. A shady area that receives a few hours of indirect sunlight per day is ideal for the growth of this plant. If grown indoors, the plant should be placed near a window that receives indirect sunlight.
Temperature Requirements
The optimal temperature range for the growth of Mycomicrothelia capitosa is between 10°C to 26°C. The plant can survive in temperatures as low as 5°C and as high as 30°C but it may not grow as well in extreme temperatures. Temperatures below 5°C and above 30°C should be avoided as they can harm the plant. The plant can thrive in both humid and dry environments but a moderately humid environment is ideal.
Soil Requirements
Mycomicrothelia capitosa is an epiphytic fungus and does not require soil to grow. It grows on the bark or wood of living or dead trees, and rocks. However, if growing the plant in a container, a well-draining potting mix that is rich in organic matter is recommended. The pH level of the soil should be between 5.5 to 7.5. The plant also requires good air circulation to thrive, so the soil should not be overly compacted or too moist.
Cultivation Methods for Mycomicrothelia capitosa
Mycomicrothelia capitosa is a tiny, epiphytic lichen that grows on the bark of trees. It is vital to ensure that the tree has healthy and well-established bark surface to support the growth of the lichen. You can collect the specimen of the lichen from trees within your botanical garden or forest. The easiest way to cultivate Mycomicrothelia capitosa is through vegetative propagation. You cut a small portion of the lichen thallus into pieces and attach it to the bark of a tree. Ensure that the bark surface is moist, and if possible, cover the lichen with a plastic wrap and a rubber band to keep it away from direct sunlight.
Watering Needs for Mycomicrothelia capitosa
Mycomicrothelia capitosa thrives in humid to moist environments, making it necessary to monitor the moisture levels of the tree bark hosting the lichen carefully. The lichen does not have roots to absorb water, and thus depends entirely on water absorbed through the host bark surface. In case the area experiences drought, you can mist the surrounding environment to maintain humidity. Make sure not to wet the lichen to avoid damaging it.
Fertilization for Mycomicrothelia capitosa
Lichens like the Mycomicrothelia capitosa absorb nutrients and minerals from the surrounding environment. Avoid using fertilizers on this lichen as they contain chemicals that can harm the lichen. Instead, cultivate it in areas with minimal to no air pollution to ensure the lichen gets clean air, water, and nutrients from the surrounding environment.
Pruning for Mycomicrothelia capitosa
Mycomicrothelia capitosa is a slow-growing lichen, and it is unnecessary to prune it. You can remove debris and branches from the host tree surface around the lichen to keep it access to sunlight and air. Avoid using harsh chemicals or removing the lichen, as it plays a role in balancing the ecosystem of the surrounding area.
Propagation of Mycomicrothelia capitosa
Mycomicrothelia capitosa can be propagated through vegetative and sexual methods. The following are the propagation methods:
Vegatative propagation
The vegetative propagation of Mycomicrothelia capitosa is done through fragmentation. In this method, the thallus is broken into smaller pieces, which are then placed in a suitable growing medium. The growing medium provides a favorable environment for the broken thallus to form new thalli, which grow into new plants. Vegetative propagation is mostly done in a laboratory environment, using appropriate sterile equipment and procedures.
Sexual propagation
Mycomicrothelia capitosa produces perithecia, which contain asci with eight ascospores each. The sexual reproduction of Mycomicrothelia capitosa occurs when two compatible hyphae come into contact, forming a perithecium. The perithecium contains ascospores that are released into the environment when mature, and these can then germinate into new thalli. Sexual propagation, however, is not frequently used since it typically involves factors beyond human control and cultivation.
Propagation of Mycomicrothelia capitosa is a technical process that requires specific skills and knowledge. It is essential to have the right equipment, such as climate-controlled spaces, and suitable growing media

Disease and Pest Management of Mycomicrothelia capitosa
Mycomicrothelia capitosa is a species of lichen that is generally hardy and robust, with few susceptibility issues. Nevertheless, some diseases and pests can affect its growth and quality. Here's what you need to know about disease and pest management for Mycomicrothelia capitosa.
Common Diseases
The most common disease that affects Mycomicrothelia capitosa is bacterial blotch. The disease is characterized by the formation of small black spots on the lichen thallus. Bacterial blotch can spread quickly, and infected lichen should be removed as soon as possible. To prevent this disease, ensure proper drainage and avoid overwatering.
Another common disease is the fungal infection, which appears as black or brown patches on the thallus. Fungi thrive in humid conditions, so ensure proper ventilation and do not overcrowd plants. Infected lichens should be removed immediately, and the soil should be treated with fungicides.
Pests
The most common pest that affects Mycomicrothelia capitosa is the spider mite. These tiny arachnids infest the leaves of the lichen, causing yellowing and browning of the leaves. Spider mites propagate rapidly, and a small infestation can quickly grow into a major problem. Control spider mites with insecticidal soap or neem oil.
Another pest that affects the lichen is the scale insect. The insect sucks the sap of the lichen, causing leaf wilting, yellowing, and browning. The scale tentacles may serve as a protective barrier that makes control with insecticides challenging. Mechanical control, such as removing infected leaves or washing the plant with a garden hose, is effective against scale insects.
Conclusion
While Mycomicrothelia capitosa is a hardy plant, it is still susceptible to diseases and pests. Proper plant care, including good ventilation, drainage, and avoiding overcrowding can help prevent these issues. Early detection and treatment are key to successfully managing diseases and pests that do manifest, so make sure to monitor your lichen regularly.
