Overview
Lecanora flowersiana H. Magn. is a lichenized fungus that usually grows on rocks in high-elevation areas with dry climates. The fungus was first described in 1995 by the Italian lichenologist Harrie J.M. Sipman, and was named in honor of the British lichenologist Brian John Coppins' mother, Dorothy Flowers.
Common Names
Lecanora flowersiana is commonly referred to as Flowers' rim lichen due to its unique look and its name's origins.
Appearance
Lecanora flowersiana forms a thick and convex thallus, reaching up to 5 cm in diameter. The rim of the thallus is often adorned with small lobes that give the plant its unique appearance. The surface color of the thallus can range from grayish-green to dark brown, and the underside is usually black. The apothecia (fruiting bodies) are usually present and can reach up to 2 mm in diameter, with a brown or blackish color.
Uses
Lecanora flowersiana has been used traditionally as a source of dye to color fabrics and yarn. The constituents responsible for the coloration are mainly unidentified, but it is known that the thallus contains different pigments such as yellow, orange, and brown hues. The plant has also been used for medicinal purposes, mainly to soothe sore throats as it contains anti-inflammatory compounds. However, these uses are not well documented and should not be attempted without proper medical guidance.

Cultivation Methods for Lecanora Flowersiana H. Magn.
Lecanora flowersiana H. Magn. is a lichenized fungus that is commonly found growing over rocks and soil surfaces. It needs a well-drained, slightly acidic to alkaline soil with a pH range of 5 to 8.5. It also needs substantial amounts of sunlight to grow and reproduce.
If you want to cultivate Lecanora flowersiana H. Magn., then you need to find a suitable location with loose soil and rock. You should not attempt to transplant the lichen to your garden as it is not a true plant and will not survive. Instead, you should try to create a natural growing environment that mimics its natural habitat.
Watering Needs for Lecanora Flowersiana H. Magn.
Watering Lecanora flowersiana H. Magn. is not necessary as it gets all its water and nutrients from the surrounding environment. However, if you are trying to propagate the lichen, then you need to ensure that the area is not completely dry.
You can mist the area occasionally to increase humidity, but overwatering can cause the lichen to rot. Also, avoid spraying any fertilizers or chemicals in the area as it can damage the lichen's delicate structure.
Fertilization for Lecanora Flowersiana H. Magn.
Lecanora flowersiana H. Magn. does not require fertilization as it gets all its nutrients from the surrounding environment. In fact, fertilizing it can harm the lichen and reduce its growth.
If you want to improve the surrounding environment, then you can try to increase the organic matter content of the soil by using compost or leaf litter. This will help provide additional nutrients for the lichen to grow and reproduce.
Pruning Lecanora Flowersiana H. Magn.
Pruning Lecanora flowersiana H. Magn. is not necessary as it does not have any leaves or stems that need to be trimmed. In fact, pruning can damage the lichen and reduce its growth.
If you want to maintain the appearance of the lichen, then you can remove any debris or fallen leaves from around the area. This will help prevent unwanted growth and provide a clean surface for the lichen to grow on.
Propagation Methods for Lecanora Flowersiana H. Magn.
Lecanora flowersiana H. Magn. is a lichen species that generally grows in rocky or gravelly habitats. While it is an attractive plant with its gray-green thallus, dazzling yellow apothecia, and prominent white rim, propagating it can be challenging. Here are some of the methods through which you can propagate the plant:
Fragmentation
The most straightforward way to propagate L. flowersiana is through fragmentation. You can obtain fragments of the plant by breaking off small pieces from the parent plant. For best outcomes, collect the fragments from the margin of the thallus as this area is more likely to grow comparatively quickly. Then erect the fragments onto a suitable substrate like a thin layer of soil or bark. You can also moisten the substrate with distilled water using a sprayer. Once placed, keep the fragments in an area with adequate humidity and air circulation. Over time, the fragments will grow further and develop their own thallus, producing another individual of L. flowersiana.
Soredia and Isidia Propagation
Soredia and Isidia are small outgrowths that you can use to propagate L. flowersiana. Soredia are powdery outgrowths containing algal cells and fungal hyphae. On the other hand, Isidia appears like branches filled with fungal hyphae and algal cells. They both occur on the surface of the thallus and easily break away once mature. You can gather soredia and isidia from the parent plant surface by lightly rubbing over the thallus with a brush or spatula. Then disperse the soredia or isidia onto a substrate, pressing them delicately down so they adhere to the substrate. Repeat this every few days to make sure they remain moist. When the new individual grows, it will form a thallus-like of the parent plant.
Ascospores Propagation
Propagation through ascospores is complicated and challenging to achieve with L. flowersiana. The spores are tiny, and cultivating them in a lab is complex. If you intend to propagate the plant from spores, collect the spores from the apothecia—the cup-like structure that covers the spores extracted from the fruiting body of the thallus. Then disperse them onto a suitable substrate and moisten it sufficiently. Over time, the spores will germinate and develop into new individuals of L. flowersiana. However, note that this method is tricky to succeed.
With the above propagation methods, you can easily propagate Lecanora flowersiana H. Magn. even though it may take time to grow a new individual.
Disease and Pest Management for Lecanora flowersiana H. Magn.
Lecanora flowersiana H. Magn., commonly known as rock sunburst lichen, is a type of lichen that is often found in the rocky areas of North America. Like most plants, it is susceptible to various diseases and pests, which may cause damage to its growth and development. Proper management of these issues is essential to ensure its survival.
Diseases
Lichen diseases are caused by several environmental factors, such as climate changes, pollution, and substrate alteration. Some common lichen diseases that can affect Lecanora flowersiana H. Magn. are:
- Lichenicolous fungi: These are fungi that grow on or within the tissues of other lichens, such as L. flowersiana. The infection may cause discoloration of the thallus, reduced growth, and even death. Removal of the infected parts or the entire plant is recommended.
- Lichen spot diseases: These are fungal infections that cause discolored spots on the thallus of the lichen. The infected portion can be removed using a sterile blade or by spraying with fungicides.
- Cyanobacterial infections: Cyanobacteria are a group of bacteria that can grow within the thallus of L. flowersiana. The infection can result in the production of toxins that harm the plant. The removal of the infected parts and reducing the exposure to high-intensity light can help manage the issue.
Pests
Like other plants, Lecanora flowersiana H. Magn. is susceptible to pests that can damage the thallus or reduce its growth. Some common lichen pests are:
- Snails and Slugs: These pests can cause mechanical damage to the thallus, leading to reduced growth and reproduction. Handpicking, using barriers, or applying molluscicides can manage the situation.
- Herbivores: Deer and other small mammals may feed on the lichen, causing extensive damage. Preventing access to the area or using repellents can help reduce herbivore activities.
- Insects: Some insects, such as scales and aphids, can feed on the lichen, reducing the plant's photosynthetic ability and growth. Insecticides, biological control, and removal of infected parts can help manage pest populations.
Overall, proper management of diseases and pests can help Lecanora flowersiana H. Magn. thrive in its natural habitat.
