Importance and role

Importance of genus to ecosystem

Species of Didymellopsis are lichenicolous. As saprotrophs, they play a role in nutrient recycling in the ecosystem. They also live on lichens as host-specific parasites and in mutual relationship with cyanobacterial photobionts (Hawksworth et al. 2011).


Industrial relevance and applications

There are currently no industrial applications of Didymellopsis.


Quarantine significance

No biocontrol agent has been reported from Didymellopsis. Further studies are needed.


Biochemical importance of the genus, chemical diversity or applications

The chemical diversity of Didymellopsis has not been investigated


Diversity of the genus

Didymellopsis comprises six species. All species in Didymellopsis have been reported on lichens with cyanobacterial photobionts. D. perigena has been found on Catapyrenium squamulosum (Verrucariaceae) which is associated with cyanobacteria surrounding the host thallus. D. nephromatis has been reported from Nephroma cellulosum (Nephromataceae). Didymellopsis has been reported in countries such as Ecuador and Rio. Comprehensive studies are likely to discover more species of Didymellopsis.
