Distribution and Habitat
- Dirinaria is mainly a pantropical and subtropical genus with a widespread distribution, especially in tropical regions.
- Specific locations mentioned include:
- Thailand (Dirinaria picta)
- South Korea (Dirinaria applanata and Dirinaria picta)
- Taiwan (Dirinaria aegialita)
- Galapagos Islands (Dirinaria picta)
- Singapore (Dirinaria picta)
- Texas, USA (Dirinaria aspera)
- Often found growing on tree trunks.
Ecological Role
- Used as bioindicators of heavy metal pollution in studies.
Morphological Characteristics and Growth Habits
- Dirinaria is a genus of lichenized fungi.
- It is described as encrusting and arboreal.
- Some species have a scarlet red upper part.
- General description of a gelatinous lichen: Narrow lobed, tightly attached, with underside black and lacking.
Genetic Information
- A non-reducing polyketide synthase gene (DnPKS, 8162 bp) has been characterized from Dirinaria applanata. This gene is down-regulated by sucrose and up-regulated by other factors.
Interactions with Other Organisms
- Dirinaria is a symbiotic organism consisting of a fungus and algae.
- Often found growing alongside Trentepohlia algae.
Quirky Facts
- A study focused on enhancing dyeing efficiency and fastness properties of natural dyes from Dirinaria picta using ultrasound method.
- A monograph dedicated to the lichen genus Dirinaria was published with a physical spine on the cover!
