Importance and role

Importance of genus to ecosystem

Species of Austrostigmidium are commensalistic. Austrostigmidium interacts with its host Mastodia tessellate but do not cause any deformations or galls in the host thallus (Hawksworth 1982). Infection by A. mastodiae is not harmful to the host.

 

Industrial relevance and applications

There are currently no industrial applications of Austrostigmidium.

 

Quarantine significance

No biocontrol agent has been reported from Austrostigmidium.

 

Biochemical importance of the genus, chemical diversity or applications

The chemical diversity of Austrostigmidium is unknown.  Further studies are needed.

 

Diversity of the genus

Austrostigmidium comprises only one species known on Mastodia tessellate (Verrucariaceae) in Antarctica. Many more species of Austrostigmidium can be discovered from comprehensive studies.
