Gintarasia is a genus of lichen-forming fungi in the family Graphidaceae. It has seven species, all of which are found in Australia. Gintarasia species are corticolous (bark-dwelling), crustose lichens with a form.
Gintarasia was formally proposed as a new genus in 2013 by Ekaphan Kraichak, Robert Lücking, and Helge Thorsten Lumbsch. Within the family Graphidaceae, it is classified in the subfamily Graphidoidae, and tribe Thelotremateae. The genus is named in honour of Gintaras Kantvilas, a Tasmanian lichenologist who has made significant contributions to the study of lichenology in Australia, particularly in Tasmania, including the taxonomy of Tasmanian Graphidaceae.
The genus is characterized by a greyish-green to olive-green thallus covered by a or ; large ascomata with exposed and thick s; a fused, hyaline to yellowish with lateral ; a non- hymenium; hyaline, non-amyloid or amyloid ; and the presence of depsidones of the protocetraric or stictic acid .
All species of Gintarasia occur in Australia.
The taxon invalidly published as Gintarasia elixii is now known as Topeliopsis elixii.
