If it outgrows its substrate, the best practice is to transfer it to a more significant substrate, such as a log, to prevent damaging the lichen's structure. It is crucial to avoid exposing the lichen to any physical damage as it can halt its growth and harm its overall health.
Propagation of Thamnolia subvermicularis Asah.
Thamnolia subvermicularis Asah. is a crustose lichen that usually grows on soil or rocks. The propagation of this plant can be achieved through two methods: vegetative propagation and spore propagation.
Vegetative Propagation
Vegetative propagation of Thamnolia subvermicularis Asah. can be easily achieved because it grows slowly and forms small patches. It can be propagated by separating small pieces of the lichen thallus and planting them in suitable conditions.
The separated thallus should be placed on a damp rock or soil in a shaded area with low light intensity. The thallus should be lightly pressed into the growing medium to maintain contact. After a few weeks, new growth will start emerging from the separated thallus.
Spore Propagation
Propagation through spores is challenging as Thamnolia subvermicularis Asah. produces spores in limited quantities and irregularly. However, spore propagation is essential for the preservation of rare and threatened lichens.
The spores can be collected from mature fruiting bodies of Thamnolia subvermicularis Asah. using a sterile brush and placed on a growing medium such as agar. The growing medium should provide suitable conditions for germination.
The agar should be kept in low light intensity and high humidity to ensure growth. Once the spores have grown large enough to form thalli, they can be transferred to their growing medium. After a few weeks, the spores will start to form small thalli.
Propagation of Thamnolia subvermicularis Asah. can be achieved through both vegetative and spore propagation. Vegetative propagation is straightforward and can be achieved by separating small thallus patches and planting them in suitable conditions. Whereas spore propagation is challenging but essential for preserving rare and threatened lichens.
